Pt on Atomic-Layered WO3 Islands: Electronic Tuning of Platinum–Tungsten Heterostructures for Highly Efficient Low-Temperature VOC Combustion

Adjusting the electronic state of noble metal catalysts on a nanoscale is crucial for optimizing the performance of nanocatalysts in many important environmental catalytic reactions, particularly in volatile organic compound (VOC) combustion. This study reports a novel strategy for optimizing Pt catalysts by modifying their electronic structure to enhance the electron density of Pt. The research illustrates the optimal 0.2Pt-0.3W/Fe
