Abstract

Selective photoreduction of CO₂ to CO, CH₄, and C_2,3 paraffins was directed by increasing ultraviolet-visible light intensity over an Fe–ZrO₂ photocatalyst. Fe⁰ nanoparticles sequentially reduced COH—transferred from the ZrO₂ surface—into CH_x species and hydrocarbons, facilitated by light-induced heating to ∼452 K.
