Infrared light dual excitation of Ni-phytate-sensitized ZnIn2S4 with sulfur vacancies for enhanced NIR-driven photocatalysis

A molecular semiconductor photocatalytic system consisting of ZnIn 2 S 4− x and phytic acid nickel achieved a hydrogen evolution reaction of 119.85 μmol h −1 g −1 under λ > 800 nm light due to its dual excitation mechanism.
