Synergetic Effects of Pd⁰ Metal Nanoparticles and Pd²⁺ Ions on Enhanced Photocatalytic Activity of ZnWO₄ Nanorods for Nitric Oxide Removal

Doping and novel metallic nanoparticles loading on the photocatalyst are two effective means to enhance its photocatalytic activity. In our study, Pd0/Pd2+-co-modified ZnWO4 nanorods were fabricated by a two-step hydrothermal process and room-temperature reduction method. The performance of the as-prepared samples was evaluated through the photocatalytic nitric oxide (NOx) removal under simulated solar and visible-light irradiation....
