Abstract Nanostructured TiO 2 is one of the best materials for photocatalysis, thanks to its high surface area and reactivity, but large energy bandgap (3.2 eV) hinders use entire solar spectrum. Here, it proposed that defect‐engineered nanostructured photocatalysts are obtained by hydrogenation strategy extend light absorption up near‐infrared region. It demonstrated hydrogenated or colored hollow spheres (THS) composed hierarchically assembled nanoparticles result in much broader...
The urea oxidation reaction (UOR), with its low thermodynamic potential, offers a promising alternative to the oxygen evolution (OER) for efficient hydrogen production. However, sluggish kinetics still demand development of an electrocatalyst. In this study, critical role Ru doping in Fe₂TiO₅ is demonstrated accelerate UOR kinetics. computational finding confirmed feasibility approach, guiding experimental synthesis Fe2-xRuxTiO5. Benefitting from surface properties and electronic structure,...
Abstract Basic insight into the structural evolution of electrocatalysts under operating conditions is substantial importance for designing water oxidation catalysts. The first‐row transition metal‐based catalysts present state‐of‐the‐art oxygen reaction (OER) performance alkaline conditions. Apparently, confinement has become an exciting strategy to boost these van der Waals (vdW) gaps metal dichalcogenides are acknowledged serve as a suitable platform confine This study focuses on...
Hierarchical Nanostructures In article number 2212486, Elisa Moretti, Alberto Vomiero, and co-workers, applied TiO2 hollow spheres with defect-engineered surface as highly efficient photocatalysts. The structure results in strongly confined solar light, defects boost the photogeneration of active charges for photocatalytic processes. Advanced spectroscopies revealed presence oxygen vacancies bulk Ti3+ centers, which enabled strong photodegradation a target drug (Ciprofloxacin) under...
Abstract Environmental pollution is a complex problem that threatens the health and life of animal plant ecosystems on planet. In this respect, scientific community faces increasingly challenging tasks in designing novel materials with beneficial properties to address issue. This study describes simple yet effective synthetic protocol obtain nickel hexacyanoferrate (Ni‐HCF) nanocubes as suitable photocatalyst, which can enable an efficient photodegradation hazardous anthropogenic organic...

Abstract Cerium‐containing titania nano‐octahedra (CeTNOh) are obtained by ultrasonication‐hydrothermal synthesis of Ce‐containing titanate nanowires (0.35, 0.46, and 0.70 Ce mol %) from commercial TiO2 (Degussa P25). CeTNOh tested as photocatalysts to degrade a target pollutant (ciprofloxacin) under simulated solar light at mild conditions. anatase polymorphs with increasing crystallite size content increases. Hydrothermal treatments enhance the specific surface area (SSA) compared P25,...
