Abstract
To accrue the full environmental benefit of hydrogen as an energy carrier, we need to develop new visible-light-active photocatalyst. Here, the LaNi0.7Cu0.3O3, was used as a precursor and then treated at various temperatures (523–673 K) for 2 h under continuous H2 flow. Among all the resultant photocatalysts, the LaNi0.7Cu0.3O3 treated at 573 K, exhibited highest photocatalytic activity when exposed to visible-light irradiation. We characterized the samples by XRD, DRS, XPS and PL. It was found that a perovskite-related material with proper oxygen vacancies and Cu2+/Cu1+ redox couples facilitated the enhancement in photocatalytic activity.
