摘要
A new type of InVO4 micron-rods photocatalyst was successfully synthesised by a facile additive-assisted hydrothermal method as a novel O-2 evolution photocatalyst. The as-obtained micro-rods are well-crystallised with about 2 m lengths and 500 nm widths. In the authors system, the sodium dodecyl sulfate amount, as well as the reaction time and temperature, plays an important role in the formation of the InVO4 micronrods. From the UV-vis absorption spectrum, the bandgap energy of as-obtained InVO4 microrods is 2.3 eV. Under visible-light irradiation, InVO4 microrods show excellent photocatalytic O-2 production activity (2.663 mmol h(-1) g(-1)) with AgNO3 as sacrifice reagents.
