Pd doped carbon nitride (Pd-g-C3N4): an efficient photocatalyst for hydrogenation via an Al–H2O system and an electrocatalyst towards overall water splitting

A straightforward and mild protocol for photochemical in situ selective hydrogenation is described via an Al–H 2 O system as a hydrogen donor and deploying a Pd-g-C 3 N 4 photocatalyst under visible light and ambient conditions.
