Summary: In this study, atomic-scale N-doped NaTaO3@Ta3N5 core-shell cubes were prepared by nitridation of cubic NaTaO3. The core-shell heterojunctions exhibited efficient and stoichiometric evolution of H2 and O2 from photocatalytic overall water splitting, with a quantum efficiency of 2.18% at 550 nm. The successful performance was attributed to the thin Ta3N5 shell, increased lifetimes of the photogenerated charges, and the type-I band alignment that promoted smooth charge flow from N-NaTaO3 to Ta3N5. The efficiency was further improved to 6.28% by in situ deposition of a Rh@Cr2O3 core-shell cocatalyst.

Summary: In this study, precise synthesis of PdCu/Ir core/shell nanocrystals was reported, which significantly boosted oxygen evolution reaction (OER) through the exclusive strain effect. The compressive strain in the Ir shell downshifted the d-band center and weakened the binding of the intermediates, leading to enhanced OER activity. The strained nanocrystals also exhibited improved hydrogen evolution reaction (HER) activity, making them excellent catalysts for overall water-splitting electrocatalysis.

Summary: This study employs ab initio quantum dynamics simulation to investigate the effect of bulk defects on carrier dynamics in semiconductors. By using BiVO4 with oxygen vacancies as a model system, a spin protection mechanism for suppressing charge recombination is demonstrated. The results show that the carrier lifetime is significantly improved in the high spin defect system, and can be optimized by tuning the oxygen vacancy concentration to minimize nonradiative relaxation. This work addresses ambiguities in the literature and provides a route for defect engineering of semiconductors with enhanced carrier dynamics.

Summary: Aluminum-doped SrTiO3 nanoparticles were synthesized with controllable aluminum doping by a mild hydrothermal method, and the photocatalytic overall water splitting was studied. The results showed an excellent photocatalytic performance with a H-2 production rate of about 4.1 mmol h(-1) g(-1) and an O-2 production rate of about 1.9 mmol h(-1) g(-1). This improvement in performance was attributed to the tuned surface band bending of SrTiO3 achieved by regulation of the Fermi level, which enhanced charge separation and accelerated the redox reaction.

Summary: The development of a universal strategy for designing photocatalysts with precise structure regulation is necessary to achieve efficient hydrogen production from water splitting. This study demonstrates the universality of a supramolecular precursor-based route for synthesizing ultrathin porous carbon nitride photocatalysts by incorporating various amino acids, enabling simultaneous production of H2 and H2O2 from pure water splitting. The improved photocatalytic performance is attributed to the molecular structure regulation of carbon nitride photocatalysts with aldehyde functional groups, which promotes adsorption/desorption processes and charge-carrier dynamics.
