MOF-derived bimetallic core–shell catalyst HZSM-5@ZrO2–In2O3: high CO2 conversion in reverse water gas shift reaction

The bicomponent core–shell catalyst HZSM-5@ZrO2–In2O3 was synthesized via the decomposition of In(NO3)3/HZSM-5@UIO-66, which was obtained by impregnating HZSM-5@UIO-66 with In(NO3)3 solution. The bimetallic oxide particles of ZrO2–In2O3 were formed through the simultaneous decomposition of UIO-66 and In(NO3)3, and were anchored to the surface of the HZSM-5 core. The HZSM-5@ZrO2–In2O3 catalyst exhibited 31.1% CO2 conversion with 96.3% CO selectivity at 400 °C for the reverse water gas shift reaction.
