TiO2 semiconductor has the disadvantages of energy bandwidth, low photo-quantum efficiency, and electron-hole pair easy recombination, which makes TiO2 semiconductor photocatalytic materials cannot be widely used efficiently. Here, a simple and low-cost method is used to prepare TiO2/C/Cu hybrid by in-situ carbon reduction by chemical vapor deposition. During high-temperature calcination, an amorphous carbon is formed on the surface of anatase TiO2, and CuO is reduced by in-situ carbon to obtain Cu. Partial Cu-doping into TiO2 introduces defects, and in-situ Cu and C loads act as electron traps to reduce photogenerated electron/hole recombination. Compared with the original TiO2, the TiO2/C/Cu hybrids have a narrow band gap (2.77 eV) and abundant defect active sites and have excellent photocatalytic activity to improve the degradation of formaldehyde (HCHO) and methyl orange (MO) under visible light. In addition, after 4 cycles, the degradation of HCHO and MO still maintained excellent stability. This innovation has many potential applications in the future, including air purification and industry.

Photovoltaic thermal (PVT) systems represent an advanced evolution of traditional photovoltaic (PV) modules designed to generate electrical and thermal energy simultaneously. However, achieving optimal and commercially viable performance from these systems remains challenging. To overcome this issue, in this research, multiwalled carbon nanotube (MWCNT) enhanced phase change materials (PCMs) integrated with PVT system to enhance electrical and thermal performance has been studied. An experimental investigation with three different configurations, PVT, PCM integrated PVT (PVTPCM), and MWCNT enhanced PCM integrated PVT (PVTNePCM) systems, was carried out under varying solar radiations and a water flow rate of 0.013–0.016 kg/s compared to conventional PV system. A two-step technique was employed to formulate the nanocomposites, and the energy performance of both PV and PVT systems assessed experimentally. The performance of PVTPCM and PVTNePCM systems was evaluated using the TRNSYS simulation technique. The formulated nanocomposite exhibited a 71.43% enhancement in thermal conductivity, a significant reduction in transmittance up to 92% and remained chemically and thermally stable. Integration of NePCM in the PVT system resulted in a notable decrease in panel temperature and a 25.03% increase in electrical efficiency compared to the conventional PV system. The highest performance ratio and overall efficiency for PVTNePCM were 0.55 and 81.62%, respectively, at a flow rate of 0.013 kg/s. The energy payback periods of PVTNePCM, PVTPCM, and PVT setup were 4.7, 4.8 and 5.6 years, respectively. Additionally, a significant improvement in thermal efficiency were observed for PVTPCM and PVTNePCM systems compared to water-based PVT systems, due to the energy stored in the thermal energy storage material.

Perovskite solar cells (PSCs) have made significant strides in power conversion efficiency (PCE), but their commercialization remains limited by stability issues. Additionally, the high cost of electrodes like gold necessitates the exploration of more affordable alternatives such as carbon (graphene). In this study, we present an approach that combines material dimensionality control and interfacial passivation using post-device treatment with phenethylammonium iodide (PEAI), an organic halide salt, to enhance the efficiency of carbon-based PSCs. Effective defect passivation is key to further improving the PCE and open-circuit voltage (VOC) of PSCs. Our results show that PEAI successfully passivates defects on the perovskite surface, significantly reducing non-radiative recombination. As a result, we achieved carbon-based PSCs with an impressive efficiency of 19.3%, demonstrating excellent stability under maximum power point tracking (MPPT) for over 900 h.

Employing a Step-scheme (S-scheme) configuration combined with a cocatalyst offers an effective approach to boost the photocatalytic efficiency of nano-heterostructures. In this study, Ag/AgO nanoparticles were integrated into a 2D/2D heterojunction (g-C3N4/Ni3V2O8) for the photocatalytic degradation of amoxicillin and ciprofloxacin under visible light exposure. Various comprehensive investigative techniques were utilized to verify the composition, formation, and band structure of the g-C3N4/Ni3V2O8–Ag/AgO heterostructure. The embedded Ag/AgO nanoparticles play a dual role: capturing carriers of charge and encouraging electron-hole separation, thus creating a heterojunction of the p-n S-scheme that improves the electrons and holes redox potential for surface reactions. The 2D/2D morphology enables substantial interfacial contact, while Ag/AgO nanoparticles act as cocatalysts, improving electron extraction, affecting product selectivity, and boosting catalytic activity. The optimized g-C3N4/Ni3V2O8–Ag/AgO composite exhibits significant photocatalytic degradation of ciprofloxacin (CIP) and amoxicillin (AMX) under the influence of visible light, reaching elimination rates of 58.8% and 62.1% within 270 min, respectively. Additionally, •O2⁻ and h⁺ are the primary active species, with •O2⁻ leading the photocatalytic elimination of CIP and AMX. This study highlights a potential strategy to developing photocatalysts with a high elimination efficiency of antibiotics by harnessing the enhanced reducing and oxidizing capabilities of S-scheme heterojunctions through meticulous structural configuration.

In recent years, antimony-based chalcogenides have gained attention as exciting prospects for next-generation thin-film photovoltaics. Binary Sb2S3 thin films are up-and-coming for optoelectronic applications due to their remarkable stability, simple composition, suitable charge transport, and facile and cost-effective synthesis. Contrary to other well-established chalcogenide-based solar cells, the power conversion efficiency (PCE) of Sb2S3 solar cells is significantly lower. In light of this, it is imperative to perform a thorough summary and exploration of the performance of Sb2S3 thin-film solar cells, identify the primary issues, and develop viable solutions to enhance their PCE. This review thoroughly analyzed Sb2S3 photovoltaic devices, revealing their significant advances and challenges in the last decade. This review thoroughly analyzes and discusses the most recent developments in Sb2S3 solar cells, including their properties, fabrication processes, and engineering strategies established to improve efficiency. In conclusion, the outlook and prospects for the further advancement of Sb2S3 solar cells are discussed.

2,5-Furandicarboxylic acid (FDCA), an excellent precursor for producing value-added green polymers, has recently garnered much attention. Traditional methods for oxidizing 5-Hydroxymethylfurfural (HMF) to FDCA typically require harsh conditions, such as high pressure, high temperature, and non-eco-friendly reactants, making them neither green nor economical. In this study, we present a novel photocatalytic system utilizing a plasmonic antenna effect to enhance Pd clusters supported on ceria (CeO2). This system drives the transformation from HMF to FDCA under ambient conditions, achieving an impressive yield of over 90% within 4 h under green light irradiation. Notably, the palladium content in this system is minimal. This discovery could pave the way for the development of new photocatalytic systems with varied nanostructures or elemental compositions for efficient chemical reactions.

In this study, a deep eutectic solvent (DES) from benzenesulfonic acid and choline chloride (BZSA-ChCl-DES) was prepared for the treatment of high free fatty acids (FFA) in acidic crude palm oil (ACPO). The DES was impregnated into activated carbon (AC-DES) to produce a supported catalyst used in a trickle bed reactor (TBR) for FFA esterification. Under optimal conditions, using 8 g of AC-DES at 60 °C, with ACPO and methanol flow rates of 1 mL/min and 4 mL/min, respectively, the TBR successfully treated 3.5 L of ACPO. A batch reactor, used for comparison, showed that the continuous TBR process required less catalyst per gram of treated oil (2.87 mg catalyst/g) which can enhance the recyclability. Moreover, the continuous process could sustain up to five recycle runs that can treat 1.5 L under optimal conditions (3.5 wt% catalyst dosage, 10:1 M ratio, 60 °C reaction temperature, and 30 min). This approach presents a promising continuous approach for converting high FFA to fatty acid methyl ester (FAME) for biodiesel production.

In the current work, an innovative eco-friendly sensor using ceria integrated cobalt oxide nanosheets immobilized on LCD monitor (Ce@Co-EcoR) recycled from E-waste is presented. The Ce@Co-EcoR nanocomposite was thoroughly investigated using appropriate characterization techniques. This nanostructured electrode was employed to construct an electrochemical sensor to detect mercury. It showed a very low detection limit of 2.8 ppb, a wide detection ranges from 16 to 620 ppb, and a good sensitivity of 158.28 μA cm2.ppm−1. The sensor applicability was verified by performing interference, repeatability, stability studies. It was also applied to control the purity of sea water. This work underscores the potential of incorporating recycled materials onto sensor technology, not only to control environmental pollution, but also to promote sustainable practices in scientific innovation.
