Traditional heterogeneous catalysis that requires high temperatures to overcome reaction barriers often activates undesired side reactions that must be mitigated. Photocatalytic reactions on semiconductors can proceed near room temperature but are primarily used for reactions that require little selectivity. Here we introduce rhodium nanoparticles as a compelling new photocatalyst whose excellent catalytic and plasmonic properties combine to reduce the activation energy and selectively determine products for the important carbon dioxide hydrogenation reaction. A key challenge in studying such plasmonic catalysis is to separate the contribution of heat and light generated hot electrons. We designed and performed careful experiments to clearly separate these two different contributions and their effect on the overall reactivity of the catalyst. It demonstrated that light and heat can work together to accelerate important chemical reactions.
