Sustainable and clean hydrogen development has been considered a mainstream trend in contemporary energy research. Heterogenous photo(electro)catalysis is a promising approach to producing hydrogen in an environmentally friendly manner. Perovskites have emerged as an inexpensive, earth-abundant, and easily fabricated semiconductor material for photo(electro)catalysis. However, some of their shortcomings have limited the wide range of applications. In this mini-review, we present the fundamentals and applications of various perovskites for photo(electro)catalytic water splitting. In addition, we summarize advanced strategies for photo(electro)catalytic water splitting based on perovskites, focusing on the following approaches: intrinsic modulation of perovskites, functionalization of perovskites, and design of perovskite tandem systems. In summary, we point out the challenges and potential applications for perovskite solar water splitting and systematically describe various strategies to improve the photo(electro)catalysis performance of perovskites, illustrating the potential of using perovskites as key materials for solar water splitting.

Developing high efficient and stable red-emitting phosphors is very important in the areas of white lighting-emitting diode (white-LED) and plant growth. Herein, series of Eu3+-activated MF2 (M2+ = Ca2+, Sr2+, Ba2+) red-emitting nanoparticles (NPs) were synthesized at room temperature. Excited at 394 nm, these resulting NPs can emit dazzling red emissions and their fluorescence intensities are sensitive to both dopant content and host compound. Moreover, it is found that the studied samples have admirable thermal stability, high quantum efficiencies and color purities, which can be regulated via changing host material. To assess the possible application of final products, three different white-LEDs were packaged by using Eu3+-activated MF2 (M2+ = Ca2+, Sr2+, Ba2+) red-emitting NPs. Clearly, these manufactured white-LEDs can produce glaring warm white with satisfied electroluminescence behaviors, i.e. low correlated color temperature (<5000 K) and high color rendering index (>80). Furthermore, via using the designed NPs, three red-emitting LEDs were also fabricated so as to identify their applications in plant growth. Our findings imply that Eu3+-activated MF2 (M2+ = Ca2+, Sr2+, Ba2+) NPs are well-suited for dual-functional lighting as red-emitting converters in the realms of white-LED and artificial plant growth LED.

The utilization of color patterns has been widely employed in encryption and displays. Printing-based nanostructures are gaining traction in color displays, showcasing remarkable resolution but facing limitations in reconfigurability. Here, we demonstrate a flexible scanning process using optical tweezers to trap silicon nanoparticles (SiNPs) for converting their trajectories into vibrant dynamic color patterns. In this process, the optical potential well stably captures a single SiNP while moving in three-dimensional space at a speed of about 1000 μm/s, leading to the display of dynamic color patterns due to persistence of vision (POV). Leveraging the tunable ability provided by Mie resonances within the visible band, the scattering color can be altered simply by adjusting the number of trapped SiNPs, thereby enabling the creation of tunable high-saturation color patterns. This strategy is further explored for flexible design of composite images with potential applications in anti-counterfeiting and dynamic display.

Copper metal is widely electroplated for microelectronic interconnections such as redistribution layers (RDL), pillar bumps, through silicon vias, etc. With advances of multilayered RDL, via-on-via structures have been developed for ultrahigh-density any-layer interconnection, which expects superconformal filling of interlayer low aspect-ratio vias jointly with coplanar lines and pads. However, it poses a great challenge to electrodeposition, because current via fill mechanisms are stemming from middle to high aspect-ratio (>0.8) vias and lacking applicability in low aspect-ratio (<0.3) RDL-vias, where via geometry related electric-flow fields coupling must be reconsidered. In the present work, a four-additive strategy has been developed for RDL-vias fill and thoroughly investigated from additive electrochemistry, in situ Raman spectroelectrochemistry, and quantum chemistry perspectives. A novel adsorbate configuration controlled (ACC) electrodeposition mechanism is established that at weak-convection bilateral edges and lower corners, the adsorbate displays a weakly-adsorbing configuration to assist accelerator-governed deposition, whereas at strong-convection center, the adsorbate exhibits a mildly-adsorbing configuration to promote leveler-determined inhibition. Deposit profiles can be tailored from dished, flat to domed, depending on predominance of leveler over accelerator. This study should lay theoretical and practical foundations in design and application of copper electroplating additives of multiple adsorbate configurations to cope with complicated interconnect scenarios.

The construction of a well-defined and efficient Z-scheme heterostructure with enhanced photogenerated charge carriers and their rapid transfer is vital for realizing efficient photocatalytic hydrogen production, to achieve carbon neutrality. Herein, we study the H2 evolution reaction by rationally constructing a hybrid Au-anchored UiO-66-NH2 with localized surface plasmon resonance (LSPR) properties, embedded with ZnIn2S4/MoS2 nanosheets. Interestingly, the synergistic effect of excellent heterojunction, tunes additional catalytic active sites, provides effective separation of photogenerated charges at the junction interface and establishes a dedicated microenvironment for the boosted electron transfer. Notably, the optimized hybrid photocatalyst (Au6@U6N)15/ZIS/MS5 exhibits highly efficient H2 generation of 58.2 mmol g−1 h−1, which is almost 16 and 1.5 folds of the pristine ZIS and MS/U6N/ZIS, correspondingly. It has an apparent quantum efficiency of 19.6% at a wavelength of 420 nm, surpassing several reported MOF-based ZnIn2S4 photocatalytic H2 evolution activities. Significantly, this research provides insights into the design of interface-engineered plasmonic MOF with layered encapsulated heterostructures that elucidate the role of plasmonic LSPR effect and efficiently regulate the charge transfer with enhanced microchannels, hence boosting the visible-light-driven photocatalytic activity for realizing efficient green energy conversion.

Electronic skin has showcased superior sensing capabilities inspired from human skin. However, most preceding studies focused on the dermis of the skin rather than the epidermis. In particular, the pseudo-porous structural domain of the epidermis increases the skin's tolerance while ensuring its susceptibility to touch. Yet, most endeavors on the porous structures failed to replicate the superior sensing performance of skin-like counterparts in terms of sensitivity and/or detection range. Stimulated by the strategy that the epidermis of the skin absorbs energy while producing ionic conduction to the nerves, this work initiatively introduced an easy-to-produce, and low-cost pressure sensor based on ionic-gel foam, and achieved a high sensitivity (2893 kPa−1) within a wide pressure range (up to ∼1 MPa), which ranked among the best cases thus far. Moreover, the factors affecting the sensor performance were explored while the sensing principles were enriched. Inspiringly, the plantar pressure measurement by harnessing the as-prepared sensor unveiled an ultra-broad detection range (100 Pa-1 MPa), thus delivering a huge application potential in the field of robot and health monitoring.

Thick and highly conductive poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate films with ideal porous structure are fulfilling as electrodes for supercapacitors. However, the homogeneous micro-structure without the aid of templates or composite presents a significant obstacle, due to the intrinsic softness of the dominant PSS component. In this study, we have successfully developed a porous configuration by employing a solvothermal approach with ethylene glycol (EG) as the solvent. The synergistic action of elevated pressure and temperature was crucial in prompting EG to tailor the microstructure of the PEDOT:PSS films by removing non-conductive PSS chains and improving PEDOT crystallinity, and the formation of a porous network. The resulting porous PEDOT:PSS films exhibited a high conductivity of 1644 S cm−1 and achieved a volumetric capacitance record of 270 F cm−3, markedly exceeding previous records. The flexible all-solid-state supercapacitor assembled by the films had an outstanding volumetric capacitance of 97.8 F cm−3 and an energy density of 8.7 mWh cm−3, which is best one for pure PEDOT:PSS-based supercapacitors. Grazing-incidence wide-angle X-ray scattering, X-ray photo-electron spectroscopy, and other characterizations were carried out to characterize the structure evolution. This work offers an effective novel method for conducting polymer morphology control and promotes PEDOT:PSS applications in energy storage field.

Nowadays, high-stable and ultrasensitive heavy metal detection is of utmost importance in water quality monitoring. Nanoparticle-enhanced laser-induced breakdown spectroscopy (NELIBS) shows high potential in hazardous metal detection, however, encounters unstable and weak signals due to nonuniform distribution of analytes. Herein, we developed an interface self-assembly (ISA) method to create a uniformly distributed gold nanolayer at a liquid-liquid interface for positive heavy metal ions capture and NELIBS analysis. The electrostatically self-assembled Au nanoparticles (NPs)-analytes membrane was prepared at the oil-water interface by injecting ethanol into the mixture of cyclohexane and Au NPs-analytes water solution. Then, the interface self-assembled Au NPs-analytes membrane was transformed onto a laser-processed superhydrophilic Si slide for detection. Three heavy metals (cadmium (Cd), barium (Ba), and chromium (Cr)) were analyzed to evaluate the stability and sensitivity of the ISA method for NELIBS. The results (Cd: RSD = 3.6 %, LoD = 0.654 mg/L; Ba: RSD = 3.4 %, LoD = 0.236 mg/L; Cr: RSD = 7.7 %, LoD = 1.367 mg/L) demonstrated signal enhancement and high-stable and ultrasensitive detection. The actual sample detection (Cd: RE = 7.71 %, Ba: RE = 6.78 %) illustrated great reliability. The ISA method, creating a uniform distribution of NP-analytes at the interface, has promising prospects in NELIBS.

Intelligent polymers have garnered significant attention for enhancing component safety, but there are still obstacles to achieving rapid self-healing at room temperature. Here, inspired by the microscopic layered structure of mother-of-pearl, we have developed a biomimetic composite with high strength and self-repairing capabilities, achieved by the ordered arrangement of pearl-like structures within a flexible polyurethane matrix and GO nanosheets functionalized by in situ polymerization of carbon dots (CDs), this biomimetic interface design approach results in a material strength of 8 MPa and toughness (162 MJ m−3), exceptional ductile properties (2697 % elongation at break), and a world-record the fast and high-efficient self-healing ability at room temperature (96 % at 25 °C for 60 min). Thereby these composites overcome the limitations of dynamic composite networks of graphene that struggle to balance repair capability and robustness, and the CDs in situ loaded in the interfacial layer inhibit corrosion and prevent damage to the metal substrate during the repair process. (The Ƶf=0.01Hz was 1.81 × 109 Ω cm2 after 2 h of healing). Besides, the material can be intelligently actuated and shape memory repaired, which provides reliable protection for developments in smart and flexible devices such as robots and electronic skins.

Owing to their multi-elemental compositions and unique high-entropy mixing states, high-entropy alloy (HEA) nanoparticles (NPs) displaying tunable activities and enhanced stabilities thus have become a rapidly growing area of research in recent years. However, the integration of multiple elements into HEA NPs at the nanoscale remains a formidable challenge, especially when it comes to the precise control of particle size, elemental composition and content. Herein, a simple and universal high-energy laser assisted reduction approach is presented, which achieves the preparation of HEA NPs with a wide range of multi-component, controllable particle sizes and constitution on different substrates within seconds. Laser on carbon nanofibers induced momentary high-temperature annealing (>2000 K and ramping/cooling rates > 105 K s−1) to successfully decorate HEA NPs up to twenty elements with excellent compatibility for large-scale synthesis (20.0 × 20.0 cm2 of carbon cloth). The IrPdPtRhRu exhibit robust electrocatalytic hydrogen evolution reaction (HER) activities and low overpotentials of 16, 28, and 12 mV at a current density of 10 mA cm−2 in alkaline (1.0 M KOH), alkaline simulated seawater (1.0 M KOH + 0.5 M NaCl), and acidic (0.5 M H2SO4) electrolytes, respectively, and excellent stability (7 days and >2000 cycles) at the alkaline HER.
高熵合金（HEA）纳米粒子由于其多元素组成和独特的高熵混合态，具有可调的活性和增强的稳定性，近年来成为一个快速发展的研究领域。然而，在纳米尺度上将多种元素整合到HEA NPs中仍然是一个艰巨的挑战，特别是当涉及到粒度、元素组成和含量的精确控制时。本文提出了一种简单、通用的高能激光辅助还原方法，该方法可以在数秒内在不同的衬底上制备出广泛、多组分、粒径和组成可控的HEA NPs。激光诱导碳纳米纤维瞬时高温退火（>2000 K）和升温/冷却速率>105 K s−1)，成功修饰HEA NPs多达20个元素，具有良好的相容性，适合大规模合成（20.0 × 20.0 cm2的碳布）。在碱性（1.0 M KOH）、碱性模拟海水（1.0 M KOH + 0.5 M NaCl）和酸性（0.5 M H2SO4）电解质中，IrPdPtRhRu在电流密度为10 mA cm−2的电催化析氢反应（HER）中表现出强大的电催化析氢活性和低过电位，分别为16、28和12 mV，并且在碱性HER中具有优异的稳定性（7天和2000次循环）。
