Dual-photon-driven hydrogen evolution in copper-based photocatalysts under near-infrared and visible light.

ABSTRACT: While the dynamic restructuring of Cu-metalated metal-organic frameworks for photocatalysis has recently been explored, its effect on electronic excitation remains under-investigated. For better mechanistic understanding, we study the light-induced activity of Cu-metalated UiO-66(COOH)₂ metal-organic framework, known as UiO-66(COOH)₂-Cu under varied irradiations, using gas-phase formic acid dehydrogenation at ambient conditions as a model reaction. A photocatalytic logic gate behavior is observed. The UiO-66(COOH)₂-Cu remains photo-catalytically OFF under visible (>390-720 nm) or near-infrared (>700 nm) light alone, but shows high H₂ production of 6.1 mmol·g⁻¹·h⁻¹ (ON state) when both are applied (≥390 nm).
