Photocatalytic oxidation of benzene to phenol using molecular O2 is one the most promising sustainable approaches for green synthesis phenol. Introducing oxygen vacancies (OVs) on semiconductor surfaces by defect engineering a strategy enhance efficiency produce due unique functions OVs in facilitating charge separation and activation O2. Herein, vacuum-sealed annealing has been well developed generate abundant surface semiconductors, such as WO3. The well-sealed quartz vial creates well-controlled low-pressure condition formation without need external energy maintaining vacuum state. Moreover, gaseous species generated during thermal process help mitigate stress-induced defects, particularly bulk defects. annealed WO3 with sufficient reduced defects shows better photocatalytic performance one-step O2, compared synthesized through Ar H2 atmospheres. present found be further applicable engineer wide range semiconducting photocatalysts optimize their properties efficient photocatalysis other OV-promoted systems.

The development of efficient, low-cost electrocatalysts for the oxygen evolution reaction (OER) is crucial advancing sustainable hydrogen production through water splitting. This study presents a dual-engineering strategy to enhance OER performance Co3O4 by synthesizing hollow microspheres assembled from nanosheets (HMNs) with abundant vacancies and highly active crystal facet exposure. Through modified one-step hydrothermal process, HMNs exposed (111) (100) facets were successfully fabricated, demonstrating superior activity compared nanocubes (NCs) only optimized Co3O4-5% exhibited low overpotential 330 mV at 10 mA cm−2 Tafel slope 69 dec−1. enhanced was attributed synergistic effects engineering defect engineering, which Co-O bond energy, increased number sites, improved conductivity. unique structure further facilitated mass transport prevented nanosheet stacking, exposing more edge sites catalytic reactions. work highlights potential geometric electronic modulation in designing high-performance catalysts energy applications.

Abstract Transition metal oxides have attracted much attention due to their good electrical conductivity, high chemical stability, and easy electronic structure modulation. However, it is still a great challenge solve the problems of sluggish reaction kinetics overpotential in alkaline hydrogen evolution (HER) poor intrinsic activity. Herein, lattice‐expanded Ni‐decorated MoO 2 array (Ni‐MoO ‐700) catalyst prepared for HER. Unlike most reported literature, decoration heteroatoms may lead lattice expansion carrier catalyst. In contrast, Ni also achieved by adjusting annealing temperature this work. The Ni‐induced lattice‐expanding effect can not only modulate but accelerate electron transfer during reaction, thus increasing its activity As result, Ni‐MoO ‐700 exhibits significantly enhanced catalytic with an 74.9 mV at 10 mA cm −2 1.0 m KOH, which far superior that advanced Ni‐ Mo‐based materials. This work provides deep insight opportunity design efficient transition oxide catalysts
