The development of green and renewable energy is becoming increasingly more important in reducing environmental pollution and controlling CO2 discharge. Photocatalysis can be utilized to directly convert solar energy into chemical energy to achieve both the conversion and storage of solar energy. On this basis, photocatalysis is considered to be a prospective technology to resolve the current issues of energy supply and environmental pollution. Recently, several significant achievements in semiconductor-based photocatalytic renewable energy production have been reported. This review presents the recent advances in photocatalytic renewable energy production over the last three years by summarizing the typical and significant semiconductorbased and semiconductor-like photocatalysts for H2 production, CO2 conversion and H2O2 production. These reactions demonstrate how the basic principles of photocatalysis can be exploited for renewable energy production. Finally, we conclude our review of photocatalytic renewable energy production and provide an outlook for future related research. Page 2 of Chen et al.

Although Ni-rich layered materials with the general formula LiNi1-x-yCoxMnyO2 (0 < x, y < 1, NCM) hold great promise as high-energy-density cathodes in commercial lithium-ion batteries, their practical application is greatly hampered by poor cyclability and safety. Herein, a LiNi0.6Co0.2Mn0.2O2 (NCM622) cathode modified with a surface self-assembling LiLaO2 coating and subsurface La pillars demonstrates stabilized cycling at 4.6 V. The LiLaO2-coated NCM622 benefits from the suppression of interfacial side reactions, which relieves the layer-to-rock salt phase transformation and therefore improves the capacity retention under high voltages. Moreover, the La dopant, as a pillar in the NCM622 lattice, plays a dual role in expanding the c lattice parameter to enhance the Li-ion diffusion capability, as well as suppressing Ni antisite defect formation upon cycling. Consequently, the dual-modified NCM622 cathode exhibits an initial Coulombic efficiency of over 85% and a high capacity of over 200 mAh g-1 at 0.1 C. A specific capacity of 188 mAh g-1 with a capacity retention of 76% is achieved at 1 C after 200 cycles within a voltage range of 3.0-4.6 V. These findings lay a solid foundation for the materials design and performance optimization of high-energy-density cathodes for Li-ion batteries.
虽然通式为LiNi1-x-yCoxMnyO2 (0 < x, y < 1, NCM)的富镍层状材料在商用锂离子电池中作为高能量密度阴极具有很大的前景,但其可循环性和安全性差极大地阻碍了其实际应用。用表面自组装的LiLaO2涂层和亚表面La柱修饰的LiNi0.6Co0.2Mn0.2O2 (NCM622)阴极在4.6 V下表现出稳定的循环。liao2包覆的NCM622有利于抑制界面副反应,从而缓解了层向岩盐的相变,从而提高了高压下的容量保持率。此外,La掺杂剂作为NCM622晶格中的支柱,在扩展c晶格参数以增强li离子扩散能力和抑制循环后Ni反位缺陷形成方面具有双重作用。因此,双改性NCM622阴极在0.1℃下具有超过85%的初始库仑效率和超过200 mAh g-1的高容量,在3.0-4.6 V电压范围内,在1℃下经过200次循环后达到188 mAh g-1的比容量,容量保持率为76%。这些发现为锂离子电池高能量密度阴极的材料设计和性能优化奠定了坚实的基础。

Energy storage devices, e.g., supercapacitors (SCs) and zinc-ion batteries (ZIBs), based on aqueous electrolytes, have the advantages of rapid ion diffusion, environmental benignness, high safety and low cost. Generally, SCs provide excellent power density with the capability of fast charge/discharge, while ZIBs offer high energy density by storing more charge per unit weight/volume. Although the charge storage mechanisms are considered different, manganese dioxide (MnO2) has proven to be an appropriate electrode material for both SCs and ZIBs because of its unique characteristics, including polymorphic forms, tunable structures and designable morphologies. Herein, the design of MnO2-based materials for SCs and ZIBs is comprehensively reviewed. In particular, we compare the similarities and differences in utilizing MnO2-based materials as active materials for SCs and ZIBs by highlighting their corresponding charge storage mechanisms. We then introduce a few commonly adopted strategies for tuning the physicochemical properties of MnO2 and their specific merits. Finally, we discuss the future perspectives of MnO2 for SC and ZIB applications regarding the investigation of charge storage mechanisms, materials design and the enhancement of electrochemical performance.

Despite the low cost, safety and high theoretical capacity of metallic zinc, zinc anodes face chronic problems, including zinc dendrites, corrosion and side reactions in aqueous zinc-ion batteries (ZIBs). Herein, a nitrogen-doped carbon nanoparticle coating layer derived from discarded cigarette filters is constructed to suppress parasitic side reactions and zinc dendrite growth. The dense coating layer isolates water from the zinc anode, effectively inhibiting side reactions. Furthermore, the special micro-mesoporous structure and sufficient zincophilic groups guarantee uniform Zn stripping/plating. Consequently, durable cycle stability (2400 cycles at a current density of 1 mA cm-2) with a stable polarization potential is achieved for symmetrical cells. The coating layer derived in this study therefore has the potential to improve the electrochemical performance of ZIBs.

Blue energy harvesting based on the ion flow obtained from seas and rivers provides a clean, stable and continuous electric output that is highly dependent on ion-selective membranes (ISMs) that conduct single ions. In recent years, ISMs constructed based on two-dimensional (2D) nanofluidics have demonstrated promising application prospects in blue energy harvesting due to their facile fabrication, excellent ion selectivity and high ion flux. In this review, the principles of 2D nanofluidics in regulating ionic transport are firstly proposed and discussed, including ion selectivity and ultrafast ion transmission, which are considered as two critical factors for achieving highly efficient blue energy harvesting. The advantages of 2D nanofluidics towards blue energy harvesting are analyzed to reveal the necessity of this review. The construction of 2D nanofluidic membranes based on several typical materials and their recent research advances in salinity gradient- and pressure-driven blue energy harvesting are also summarized in detail. Finally, the existing challenges of 2D nanofluidic membranes regarding blue energy harvesting applications are discussed to provide new insights for the development of high-performance blue energy harvesting systems based on 2D nanofluidics.

Rechargeable aqueous Zn-ion batteries (AZIBs) are considered alternative stationary storage systems for large-scale applications due to their high safety, low cost, and high power density. However, Zn anode issues including dendrite formation and side reactions greatly hinder the practical application of AZIBs. To solve the Zn anode issues, various strategies based on material designs have been developed. It is necessary to analyze and classify these strategies according to different materials, because different properties of materials determine the underlying mechanisms. In this review, we briefly introduce the fundamental issues in Zn anodes. Furthermore, this review highlights the material designs for the protection of Zn anodes in mild AZIBs. Finally, we also offer insight into potential directions in the material designs to promote the development of AZIBs in the future.

It is of vital importance to boost the intrinsic activity and augment the active sites of expensive and scarce platinum-based catalysts for advancing a variety of electrochemical energy applications. We herein report a mild electrochemical bottom-up approach to deposit ultrafine, but stable, Pt8Ag4 alloy clusters on carbon nanotubes (CNTs) by elaborately designing bimetallic organic cluster precursors with four silver and eight platinum atoms coordinated with µ,σ-bridged ethynylpyridine ligands, i.e., [Ag4(C24H16N4Pt)8(BF4)4]. The Pt8Ag4 cluster/CNT hybrids present impressively high platinum mass activity that is threefold that of commercial Pt/C toward the hydrogen evolution reaction, as a result of the cooperative contributions from the Ag atoms that enhance the intrinsic activity and the CNT supports that increase the activity sites. The present work affords an attractive avenue for engineering and stabilizing Pt-based nanoclusters at the atomic level and represents a promising strategy for the development of high-efficiency and durable electrocatalysts.

Alloying materials (e.g., Si, Ge, Sn, Sb, and so on) are promising anode materials for next-generation lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to their high capacity, suitable working voltage, earth abundance, environmental friendliness, and non-toxicity. Although some important breakthroughs have been reported recently for these materials, their dramatic volume change during alloying/dealloying causes severe pulverization, leading to poor cycling stability and safety risks. Although the nanoengineering of alloys can mitigate the volumetric expansion to some extent, there remain other drawbacks, such as low initial Columbic efficiency and volumetric energy density. Porous microscale alloys comprised of nanoparticles and nanopores inherit micro- and nanoproperties, so that volume expansion during lithiation/sodiation can be better accommodated by the porous structure to consequently release stress and improve the cycling stability. Herein, the recent progress of porous microscale alloying-type anode materials for LIBs and SIBs is reviewed by summarizing the Li and Na storage mechanisms, the challenges associated with different materials, common fabrication methods, and the relationship between the structure and electrochemical properties in LIBs and SIBs. Finally, the prospects of porous microscale alloys are discussed to provide guidance for future research and the commercial development of anode materials for LIBs and SIBs.

Lithium oxides are the most promising cathode candidates for high-performance lithium-ion batteries (LIBs), owing to their high theoretical capacity and average working voltage, which are conducive to achieving the ultimate goal of upgrading energy density. By raising the upper limit of the cutoff voltage, we may be able to further improve both the practical capacity and average voltage of lithium oxide cathodes. Unfortunately, the high-voltage operation of these cathodes results in significant challenges, namely, reduced surface structural stability and interfacial stability with electrolytes, thus degrading the electrochemical performance. Accordingly, surface/interface modification strategies, including surface coating, electrolyte regulation, binder design, and special surface treatments, are systematically summarized and comprehensively analyzed for high-voltage lithium oxide cathode materials in this review. Furthermore, the corresponding modification mechanisms are discussed in detail to better grasp the internal mechanisms for the enhanced electrochemical performance. Based on recent progress, we further propose predictable development directions for high-performance LIBs in future practical applications. This review provides new insights into various high-voltage lithium oxide cathodes and their universal surface/interface modification strategies towards advanced next-generation LIBs with high energy and power density and long cycle life.

Lithium-ion batteries (LIBs) and ceramic fuel cells (CFCs) are important for energy storage and conversion technologies and their materials are central to developing advanced applications. Although there are many crosslinking research activities, e.g., through materials and some common scientific fundamentals employed for both LIB and CFCs, crosslinking scientific aspects to achieve a comprehensive understanding are missing. There is a lack of such a review to promote and guide further research and development in the crosslinking of LIBs and CFCs. Herein, we review the existing application of LIB materials in CFCs to discover the scientific advances of lithium-ion and proton transport cooperation and identify the new directions of Li-CFCs in the future. This review is the first to propose CFC advances, especially at low temperatures (300-600 °C) by applying LIB materials to practical devices and highlight the material properties and new device functions with enhanced performance, as well as the scientific mechanisms and principles. Furthermore, we seek to deepen the scientific understanding of materials science, ion transport mechanisms and semiconductor electrochemistry to benefit both the battery and fuel cell fields.

Although there are many crosslinking research activities, e.g., through materials and some common scientific fundamentals employed for both LIB and CFCs, crosslinking scientific aspects to achieve a comprehensive understanding are missing. There is a lack of such a review to promote and guide further research and development in the crosslinking of LIBs and CFCs. Herein, we review the existing application of LIB materials in CFCs to discover the scientific advances of lithium-ion and proton transport cooperation and identify the new directions of Li-CFCs in the future.
