Abstract Photocatalytic CO 2 reduction reaction (CO RR) into high‐value‐added fuels has received significant attention, yet multiple electron and proton processes involved in RR result low selectivity. Herein, a strategy involving oxygen vacancies (Ovs)‐enriched Bi MoO 6 coated on ZIF‐67‐derived Co 3 O 4 to construct well‐defined core‐shell nanocage is developed, which drives effective photoconversion CH with nearly 100% selectivity high apparent quantum efficiency of 2.5% at 420 nm pure water under simulated irradiation. Theoretical calculations experiments exhibit that the potential difference stemming from built‐in electric field provides guarantee for occurring H oxidation set . Numerous exposed Ovs formed Bi─O bond by ethylene glycol mediated approach promotes adsorption charge separation efficiency, can optimize kinetics thermodynamics, facilitating hydrogenation key intermediate *CO generate This work new controlled vacancy generation photocatalysts achieve high‐performance methanation.

Cobalt Single‐Atom Intercalation in Molybdenum Disulfide Enhances Piezocatalytic and Enzyodynamic Activities for Advanced Cancer Therapeutics

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Abstract Piezoelectric semiconductor nanomaterials have attracted considerable interest in piezocatalytic tumor treatment. However, therapy encounters obstacles such as suboptimal piezoelectric responses, rapid electron‐hole recombination, inefficient energy harvesting, and the complexities of microenvironment. In this study, sulfur vacancy‐engineered cobalt (Co) single‐atom doped molybdenum disulfide (SA‐Co@MoS 2 ) nanoflowers are strategically designed, which exhibit enhanced effects. Specifically, introduction Co single atom not only induces lattice distortion out‐of‐plane polarization but also leads to formation numerous vacancies. These changes collectively narrow intrinsic bandgap material, facilitating effective separation migration charge carriers, enabling efficient production reactive oxygen species under ultrasound stimulation. Additionally, SA‐Co@MoS demonstrate improved enzymatic activity glutathione depletion capabilities attributed mixed valence states Co, intensifying oxidative stress cells, leading cell cycle arrest apoptosis, while inactivation peroxidase 4 ferroptosis. Both vitro vivo results indicate that can significantly eliminate cells. This study offers valuable insights into exploration doping‐enhanced sonosensitizers for cancer treatment, potentially paving way advancements field synergistic enzyodynamic therapy.
