Despite extensive efforts to develop highperformance H 2 evolution catalysts, this remains a major challenge. Here, we demonstrate the use of Cd/Pt precursor solutions for significant photocatalytic H 2 production (154.7 mmol g À 1 h À 1 ), removing the need for a pre-synthesized photocatalyst. In addition, we also report simultaneous in situ synthesis of Pt single-atoms anchored CdS nanoparticles (Pt SA -CdS IS ) during photoirradiation. The highly dispersed in situ incorporation of extensive Pt single atoms on CdS IS enables the enhancement of active sites and suppresses charge recombination, which results in exceptionally high solarto-hydrogen conversion efficiency of � 1 % and an apparent quantum yield of over 91 % (365 nm) for H 2 production. Our work not only provides a promising strategy for maximising H 2 production efficiency but also provides a green process for H 2 production and the synthesis of highly photoactive Pt SA -CdS IS nanoparticles.
A number of Pd based materials have been synthesised and evaluated as catalysts for the conversion of carbon dioxide and hydrogen to methanol, a useful platform chemical and hydrogen storage...
Despite extensive efforts to develop high‐performance H2 evolution catalysts, this remains a major challenge. Here, we demonstrate the use of Cd/Pt precursor solutions for significant photocatalytic H2 production (154.7 mmol g−1 h−1), removing the need for a pre‐synthesized photocatalyst. In addition, we also report simultaneous in situ synthesis of Pt single‐atoms anchored CdS nanoparticles (PtSA‐CdSIS) during photoirradiation. The highly dispersed in situ incorporation of extensive Pt single atoms on CdSIS enables the enhancement of active sites and suppresses charge recombination, which results in exceptionally high solar‐to‐hydrogen conversion efficiency of ≈1 % and an apparent quantum yield of over 91 % (365 nm) for H2 production. Our work not only provides a promising strategy for maximising H2 production efficiency but also provides a green process for H2 production and the synthesis of highly photoactive PtSA‐CdSIS nanoparticles.
Catalysis happens only at the surface of materials, this makes nanoparticles of particular interest in the field of catalysis because of their high surface-to-volume ratio. The exact atomic structure of nanoparticle surfaces is of particular importance in catalysis, and the expression of surface facets is largely governed by their overall structure. Typically, small metal nanoparticles will take one of three major structural isomers: decahedron, icosahedron or cuboctahedron (Figure 1). Determination of the structural isomer of a nanoparticle can be performed using high-angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) [1,2].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
