Metal Nanoshells for Enhanced Solar-to-Fuel Photocatalytic Conversion

Abstract

Preparation of next-generation photocatalysts is presented. The indium content in this four-component photocatalyst was found to play a critical role. The highest hydrogen evolution rate is 970 micrometersol/h.g. The [Zn]/[Ag] also determined the utilization of visible-light region in the solar spectrum. Samples with various [Zn]/[Ag] compositions show different photocatalytic activities in full spectrum and in visible light. Secondly, it was demonstrated that at an elevated temperature, the hydrogen evolution rate is higher. Future study will focus on improving the efficiency of our second-generation photocatalyst, create various core-shell structures, measure the hydrogen production rate, and test the stability of this composite system.
