Summary: This study presents a hydrogen production system that combines anodic and cathodic H-2 production from low-potential aldehyde oxidation and the hydrogen evolution reaction, respectively, at a low voltage of about 0.1V. Unlike conventional aldehyde electrooxidation, the low-potential aldehyde oxidation enables the hydrogen atom to recombine into H-2 gas. The assembled electrolyser requires only about 0.35 kWh of electricity input per m(3) of H-2, providing a promising avenue for the safe, efficient and scalable production of high-purity hydrogen.

Summary: In this study, a multifunctional interfacial material, BGCl, was introduced to modify the interface of perovskite solar cells. The BGCl improved electron extraction and crystal growth of perovskite by chemically linking to SnO2 and anchoring PbI2. This modification led to better energetic alignment, reduced interfacial defects, and homogeneous perovskite crystallites, resulting in highly efficient and stable performance.

Summary: By adopting the asymmetric selenium substitution strategy and using a pseudosymmetric electron acceptor, the power conversion efficiency of planar-mixed heterojunction organic solar cells (PMHJ OSCs) can be significantly improved. The increased dielectric constant and improved dimer packing lead to lower exciton binding energy, more efficient exciton dissociation, and reduced radiative recombination loss. These findings provide an effective way to develop highly efficient acceptor materials for OSCs.

Summary: Hydrogen production from water splitting using renewable electric energy is a key topic for achieving a carbon neutral future. Single atom catalysts (SACs) have emerged as a new frontier in catalysis, particularly in the hydrogen evolution reaction (HER), due to their high activity and excellent chemical selectivity. However, the influence of the neighboring coordinated atoms from the supports is often neglected in the classification of SACs. This review proposes a new classification method based on the type of supports and highlights the importance of the metal-support interaction and coordination environment. Structural designing strategies are also proposed to address the current challenges in SACs for HER.

Summary: In this study, an AgBr/BiOBr heterojunction with surface oxygen vacancies was synthesized using a simple chemical method, which showed significantly improved photoreduction rates of CO2 compared to pure BiOBr. The unique S-scheme band structure and oxygen vacancies were found to enhance the utilization of sunlight and increase the separation and transfer of photogenerated charge carriers, leading to efficient photocatalytic reduction of CO2.

Summary: Polymeric metal-organic framework (MOF)-derived composites are functional materials with exceptional chemical homogeneity, designable components, and adjustable pore size. This study presents the design of laminate-stacked sphere-shaped trimetallic CoNiMn-MOFs and the successful synthesis of CoNi/MnO@C composites, which exhibit excellent electromagnetic wave-absorbing performance. The modulation of oxygen and Mn vacancies through the introduction of heteroatoms and changes in annealing temperature contributes to the improvement of electromagnetic loss capacity.

Summary: In this study, a Fe-g-C3N4/Bi2WO6 Z-scheme heterojunction was elaborately designed for the degradation of tetracycline (TC). The performance of H2O2 decomposition in the Z-scheme heterojunction was improved by the doping of iron, enhancing the transportability of photogenerated electrons and facilitating the spread of radicals. The study also found that O-1(2) and center dot O-2- were the main active species participating in the degradation process, according to efficacy analyses and experimental results.
