Abstract
The role of methoxide species in selective formation of isobutene from CO and H 2 over ZrO 2 was investigated by means of 13C tracer method. Analysis of 13C 13C coupling in the formed isobutene showed that 12CO hydrogenation over ZrO 2 pretreated with 13CO and H 2 formed 12CH 2 = 13C( 12CH 3) 2, while 13CO hydrogenation over ( 12CH 3) 2O-adsorbed ZrO 2 formed 13CH 2 = 12C( 13CH 3) 2. It was proposed from these results that methoxide species gave central carbon of isobutene, while the other carbons came from gas phase CO. A reaction path through methoxide species was proposed.
