Rational design of bimetallic photocatalysts based on plasmonically-derived hot carriers

摘要: Hot carriers generated by plasmonic excitations have recently opened up new avenues in photocatalysis. The transfer of these energetic to adjacent molecules can promote chemical transformations that are important for hydrogen generation water splitting, CO2 reduction and degradation organic pollutants. Here, we developed optimised a hot-carrier catalytic system based on silica nanoparticles decorated with gold as source hot carriers, equipped platinum nanoclusters co-catalyst the enhancement extraction. latter plays triple role providing: surface favourable molecular adsorption; hot-electron near due field effects electron momentum relaxation facilitating across metal surface, exactly where adsorbed. combination metals nano-heterostructured devices provides platform photocatalytic processes is significant interest future solar-based clean technologies.
