Abstract

We report a noble-metal-free photocatalyst, ultrathin TiO₂ with atomic layer thickness, which is a potential catalyst for CO₂ photoreduction. An excellent liquid-product yield of 463.9 μmol g_cat⁻¹ in 8 h with 98% selectivity to alcohols was achieved, owing to sufficient surface defects favoring CO₂ adsorption/activation.
