Investigating the Metal-TiO₂ Influence for Highly Selective Photocatalytic Oxidation of Methane to Methanol.

ABSTRACT: Methane conversion to valuable chemicals is a highly challenging and desirable reaction. Photocatalysis is a clean pathway to drive this chemical reaction, avoiding the high temperature and pressure of the syngas process. Titanium dioxide, being the most used photocatalyst, presents challenges in controlling the oxidation process, which is believed to depend on the metal sites on its surface that function as heterojunctions. Herein, we supported different metals on TiO₂ and evaluated their activity in methane photooxidation reactions. We showed that Ni-TiO₂ is the best photocatalyst for selective methane conversion, producing impressively high amounts of methanol (1.600 μmol·g^-1) using H₂O₂ as an oxidant, with minimal CO₂ ev
