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

Original language description

A straightforward and mild protocol for photochemical in situ selective hydrogenation is described via an Al-H2O system as a hydrogen donor and deploying a Pd-g-C3N4 photocatalyst under visible light and ambient conditions. Water, a green solvent, provided hydrogen and the photocatalyst Pd-g-C3N4 facilitated hydrogenation with excellent yield and selectivity for a wide range of olefins and nitro compounds (&gt;99%). The robust catalyst is stable with excellent reusability for five consecutive runs. Besides recognition for its excellent photocatalytic ability, Pd-g-C3N4 has also been introduced as an efficient bifunctional electrocatalyst towards overall water splitting (both the hydrogen evolution and the oxygen evolution reaction) with excellent durability; it can catalyze both half-cell reactions in the same media (0.5 M H2SO4 solution) with Tafel slopes for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) for the catalyst being 36 and 72 mV decMINUS SIGN 1, respectively. The enhanced catalytic activities may be due to the synergistic effect among Pd and C and N of the C3N4 material. These findings point to a promising pathway to assemble a robust and efficient catalyst for both photochemical and electrochemical reactions and pave a new avenue for the development of a bifunctional photo/electrocatalyst for hydrogenation and overall water splitting.
