In situ UV-Vis DRS evidence of Cr2+ species oxidation by CO2.
In situ UV-Vis DRS investigations have revealed that the Cr(2+) species, which dominate on the surface of a CO-reduced Cr/SBA-1 catalyst, can be oxidized by CO(2) at a wide range of temperatures. Such an oxidation is a multistep process proceeding probably via carboxylate intermediates.
