Methane-based
nitridation was employed to produce wurtzite zinc-gallium oxynitride
(ZnGaNO) photocatalyst particles using Zn/Ga/CO<sub>3</sub> layered
double hydroxides (LDHs) as precursor. Introduction of methane to
nitridation would promote the formation of Zn–O bonding and
suppress shallow acceptor complexes such as V<sub>(Zn)</sub>-Ga<sub>(Zn)</sub> and Ga-O<sub>i</sub> in ZnGaNO particles. On the other
hand, high flow rate of methane would induce breaking of Ga–N
bonding and enhance surface deposition of metallic Ga atoms. After
loading with Rh and RuO<sub>2</sub>, ZnGaNO particles had free electron
density in an order of S50 > S20 > S90 > S0, which correlated
well with their photocatalytic performance upon visible-light irradiation.
The best performance of the loaded S50 was ascribed to the relatively
flat surface band bending of the particle. Methane-based nitridation
of Zn/Ga/CO<sub>3</sub> LDHs would provide a new route to tune the
surface chemistry of ZnGaNO and enhance the photocatalytic performance
to its full potential.
