Summary: The effect of alkylamine additives with different chain lengths on the performance of perovskite solar cells was studied. The length of the alkyl chain was found to have a critical effect on the structure and performance of the perovskite film. Shorter chain length additives were distributed throughout the film, with a 2D phase observable at high concentrations. In contrast, longer chain length additives phase-separated and concentrated at the film surface.

Summary: This study resolves the issue of carrier recombination on the dual surfaces of the m-BiVO4 component in water oxidation by constructing an m-BiVO4/carbon nitride (C3N4) Z-scheme heterostructure based on the m-BiVO4/reduced graphene oxide (rGO) Mott-Schottky heterostructure. The rGO effectively accumulates photogenerated electrons from m-BiVO4 and facilitates their diffusion through a highly conductive carbon network. The Z-scheme electron transfer at the heterointerface of m-BiVO4/C3N4 leads to spatial separation of electron-hole pairs and maintains strong redox potentials, resulting in significantly improved O-2 yield and the generation of center dot OH and center dot O-2(-) radicals.

Summary: Modulating the steric-electronic configuration of metal-organic centers is key for tuning the activity and selectivity of heterogeneous reactions. In this study, three different asymmetric metal-organic complexes with unique steric-electronic structures are immobilized on nanocarbon for an electron-transfer-controlled oxygen reduction reaction. The results show that acidic diamine ligands facilitate a four-electron transfer, while basic ligands drive a highly selective two-electron route, regulated by the ligand's proton transfer ability.
