WebOct 29, 2024 · The trapping of photogenerated electrons by Pd NPs trapped favored the generation of H∙ and suppressed the formation of Pd–H species. On the whole, light renders several hydrogenation reactions easier to be triggered at mild conditions via the conversion of light input to chemical energy. Meanwhile, the reaction process, following the ... Web摘要: The regulation of electron distribution of single‐atomic metal sites by atomic clusters is an effective strategy to boost their intrinsic activity of oxygen reduction reaction (ORR).Herein we report the construction of single‐atomic Mn sites decorated with atomic clusters by an innovative combination of post‐adsorption and secondary pyrolysis.
WebThe hot electrons were injected from the Au plasmonic nanoparticles into the conduction band of monolayer g-C3N4. Thus, the Au/monolayer g-C3N4composites possessed higher migration and separation efficiencies and lower recombination probability of photogenerated electron-hole pairs than those of monolayer g-C3N4.
WebThe photogenerated electrons are consumed to reduce H + into H 2 at the cathode, while holes take part in oxidation of water into O 2 and H + at the anode. Conversely, if a p-type … WebApr 30, 2024 · Furthermore, the photogenerated electrons (holes) can transfer from monolayer MoSSe (MoSeTe) to the graphene sheets by the Se side with lower (higher) potential, while the transfer of the ...
