Pt–Ti Coordination at Oxygen Vacancies Activates Single‐Atom Catalysis for Broad‐pH Hydrogen Evolution

Carbon Energy, EarlyView.
Defect engineering anchors near‐zero‐valent Pt single atoms at oxygen vacancies of TiO2, forming distinctive Pt–Ti coordination that regulates electron density and optimizes hydrogen adsorption. The vacancy‐induced metal‐support interaction facilitates efficient electron transfer and accelerates water dissociation, enabling pH‐universal hydrogen ...

Asymmetric‐Coordinated Indium Single Atoms for Highly Selective Photocatalytic CO2 Reduction

Carbon Energy, EarlyView.
This work develops an indium single‐atom photocatalyst (In‐NTO) featuring unique Inδ⁺–N3O2 coordination sites for highly selective CO2 photoreduction. The specific atomic interface steers the reaction pathway exclusively toward CO (95.9% selectivity) by lowering the overall energy barrier and converting the critical *CO protonation step from ...

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).
