Plasmonic nanoparticles/reduced graphene oxide sensitized hierarchical TiO2 nanorods for solar water splitting

Abstract

Metallic nanoparticles exhibiting distinctive localized surface plasmon resonance (LSPR) have been widely employed for photoelectrochemical (PEC) water splitting, due to their remarkable optical scattering as well as near-field nanofocusing of light, which efficiently enhance the photoactivity of semiconductors [1]. On the other hand, reduced graphene oxide (rGO) with large surface area and excellent electrical conductivity has also attracted much attention in the field of photocatalyst [2]. ? 2018 OSA - The Optical Society.
