We　evaluate　the　direct　CO2　conversion　to　light　olefins　reaction　via　a　hybrid　catalyst　of　In2O3/ZrO2　metallic　oxide　and　zeolite　SAPO34　components.　On　this　catalyst,　it　can　realize　producing　high　light　olefins　selectivity　of　77.59%　via　a　direct　tandem　catalysis　process,　that　is,　the　formed　methanol　on　the　oxygen　vacancies　surface　of　In2O3/ZrO2　in　the　first　step　will　continue　passing　through　the　SAPO34　zeolite　channel,　where　it　is　changed　into　light　olefins　simultaneously.　Even　there　are　many　studies　focused　on　this　tandem　catalysis　reaction　via　bi-functional　catalyst　in　recent　years,　however,　to　reduce　the　poisonous　byproduct　CO　is　still　in　a　big　challenge.　In　this　reaction,　large　amounts　of　poisonous　CO　will　be　easily　formed　from　reverse　water　gas　shift　reaction.　Therefore,　in　our　research,　by　optimizing　the　reaction,　the　catalyst　can　suppress　the　undesirable　CO　formation　obviously.　It　shows　good　potential　leading　to　scale-up　cause　of　the　outstanding　reaction　performance　and　its　friendly-environment　properties.　©　2019　Elsevier　B.V.
