In situUV-Vis DRS evidence of Cr super(2+) species oxidation by CO sub(2)

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