We
extend here our inspection, via first-principles dynamical simulations
supported by experiments, to the inhomogeneous photocatalytic RVO<sub>4</sub> systems. At variance with our former paper, we limit the
present analysis to the most promising photocatalysts (R = Y, Gd)
for which the addition of a Ni-based cocatalyst provides the best
activities. The specific role of Ni-based cocatalysts is elucidated,
showing that a surface Ni doping, as opposed to a bulk one, is the
most efficient way to enhance the catalytic activities of these compounds.
This is a key step in the improvement of the photocatalysts and a
roadmap to optimize the amount of Ni dopant needed for both hydrogen
and oxygen generation.
