Title: Plasmonic photocatalyst: Hot electron transfer type and hot hole-transfer type

Biography:

Shin-ichi Naya is currently working as the technical staff of Environmental Research Laboratory at Kindai University, Japan. He received his PhD in Waseda University in 2001. After a postdoctoral training in 2001-2006, he joined Kindai University since 2007. Current research focuses on hetero-nanostructure of plasmonic photocatalyt. 

Abstract

Silver and gold nanoparticles (NPs) possess strong and broad absorption in the visible region due to the localized surface plasmon resonance (LSPR). In the heteronanostructures consisting of the plasmonic metal and n-type semiconductor (n-SC), the LSPR excitation of the former can generate hot electrons inducing the interfacial electron transfer to the latter (Scheme 1). The so-called plasmonic photocatalysts taking advantage of this phenomenon have attracted much attention particularly in terms of the application to artificial photosynthesis.
