Highly Selective Photoreduction of CO₂ with Suppressing H₂ Evolution over Monolayer Layered Double Hydroxide under Irradiation above 600 nm

Although progress has been made to improve photocatalytic CO 2 reduction under visible light ( λ >400 nm), the development of photocatalysts that can work under a longer wavelength ( λ >600 nm) remains a challenge. Now, a heterogeneous photocatalyst system consisting of a ruthenium complex and a monolayer nickel‐alumina layered double hydroxide (NiAl‐LDH), which act as light‐harvesting and catalytic units for selective photoreduction of CO...
