Published: March 6, 2024

Abstract Tailoring advanced anisotropy‐driven efficient separation and migration of photogenerated carriers is a pivotal stride toward enhancing photocatalytic activity. Here, CdS‐MoS 2 binary photocatalysts are tailored into dumbbell shape by leveraging the rod‐shaped morphology CdS employing an in situ tip‐induction strategy. To further enhance activity, photo‐deposition strategy incorporated to cultivate MnO x particles on dumbbell‐shaped . The deposition effectively isolated oxidatively active sites surface, emphasizing reductively crystalline face CdS, specifically (002) face. Benefiting from its robust activity as reduction site, MoS adeptly captures electrons, facilitating H + produce hydrogen. anisotropically driven markedly mitigates Coulomb force or binding thus promoting smoother site for hydrogen evolution. evolution rate 35MnO ‐CdS‐MoS ‐3 surpasses that nearly order magnitude, achieving quantum efficiency 22.30% at 450 nm. Under simulated solar irradiation, it attains 42.86 mmol g −1 h This work imparts valuable insights design dual co‐catalysts, spatial vectorial charge migration, analysis pathways carriers.

Zn Single-Atom Catalysts Enable the Catalytic Transfer Hydrogenation of α,β-Unsaturated Aldehydes

Nano Letters, Journal Year: 2024, Volume and Issue: 24(17), P. 5197 - 5205

Published: April 18, 2024

Highly active nonprecious-metal single-atom catalysts (SACs) toward catalytic transfer hydrogenation (CTH) of α,β-unsaturated aldehydes are great significance but still deficient. Herein, we report that Zn–N–C SACs containing Zn–N3 moieties can catalyze the conversion cinnamaldehyde to cinnamyl alcohol with a 95.5% and selectivity 95.4% under mild temperature atmospheric pressure, which is first case Zn-species-based heterogeneous for CTH reaction. Isotopic labeling, in situ FT-IR spectroscopy, DFT calculations indicate reactants, coabsorbed at Zn sites, proceed via "Meerwein–Ponndorf–Verley" mechanism. also reveal high activity over stems from suitable adsorption energy favorable reaction rate-determining step sites. Our findings demonstrate hold extraordinary reactions thus provide promising approach explore advanced high-value-added chemicals.
