Fig. 6: Probe experiments for methanol conversion.
From: Selective conversion of CO2 to isobutane-enriched C4 alkanes over InZrOx-Beta composite catalyst

a Methanol conversion and product distribution for MTH in H2 atmosphere over H-Beta(40) zeolite with a methanol WHSV of 0.05 h−1. b GC-MS chromatograms of residual species in H-Beta(40) after the MTH reaction in H2 atmosphere with a methanol WHSV of 0.05 h−1 (The shadow inserts are the enlargement of GC-MS chromatograms at specified retention times). c 13C content of the confined organic species in H-Beta(40), obtained from 12C/13C methanol switching experiment.
