The transport, logistics, and deployment of fossil fuel to the front lines has shown to be a primary target for attack, proving to be a highly hazardous job for the Warfighter and a weak link for continuing operations. As such, new technological solutions are required to reduce the Warfighters dependence on sustained fuel delivery, either through reduced energy consumption or agile, on-site energy production. This work looks to develop light-driven catalytic materials that will facilitate the synthesis of energy-dense hydrocarbons through the solar-driven reduction of CO2 and hydrogen evolution from water. Metal plasmonic nanomaterials are ideal candidates to simultaneously capture solar energy and couple that power to drive catalytic reactions because of their exceptionally high extinction coefficient and plasmon-energy coupling phenomena. By synthesizing catalytically active oxides onto energy-tuned metal nanoparticles, solar energy can be used to enhance select reactions. This report presents the preliminary results on the synthesis and catalytic activity of cuprous oxide nanocompositions and a multishell material consisting of a gold nanorod core with subsequent layers of reduced graphene oxide and titanium dioxide.
