Abstract

Co-catalysts and sacrificing reagents are important components in artificial photocatalytic processes. Here we demonstrate that noble-metal loading reverses the temperature dependent photocatalytic activity trends of photocatalytic hydrogen (H₂) generation with methanol as a sacrificing reagent. This finding suggested that visible and infrared light can enhance photocatalytic H₂ generation via a heat effect over noble-metal/photocatalysts.
