Great efforts have been paid to improve the photoelectrochemical performances of FeVO4 semiconductors. However, there have rarely been reported about the modifying of FeVO4 with metal-free co-catalyst for enhanced photoelectrochemical activities. Herein, we demonstrate a facile and effective immersion method for coupling ultrathin g-C3N4 nanosheets with nanoporous FeVO4 photoelectrodes. The FeVO4/g-C...
Metal oxide photocatalysts TiO2/MoO3 and TiO2/MoO3:V2O5 have been investigated by electron paramagnetic resonance (EPR) spectroscopy under in situ light excitation. Structural identification of all paramagnetic centers (PCs) recorded, such as surface and lattice Ti3+ ions as well as Mo5+ and V4+ ions and nitrogen 14N atoms containing the unpaired electron (“N•-radicals”), have been performed. The...
