在此，PtRu固溶合金纳米颗粒通过将电催化知识转移到光催化上，实现了高性能的H-2演化反应助催化剂。采用化学多元醇法合成了直径为1.0 +/- 0.2 nm的超细PtRu合金纳米颗粒，并将其用于电/光催化。通过液相吸附和连续两步空气和H-2退火将PtRu纳米颗粒与碳和al掺杂的SrTiO3粉末相结合，确保了PtRu合金纳米颗粒的均匀沉积(
Herein, PtRu solid-solution alloy nanoparticles enable high-performance H-2 evolution reaction cocatalysts through the transfer of knowledge from electrocatalysis to photocatalysis. Ultrafine PtRu alloy nanoparticles (1.0 +/- 0.2 nm in diameter) are synthesized by using a chemical polyol method and used for electro/photo-catalyses. Integration of PtRu nanoparticles with carbon and Al-doped SrTiO3 powders via liquid-phase adsorption and successive two-step air and H-2 annealing ensures uniform deposition of PtRu alloy nanoparticles (
