Direct conversion of CO2 to hydrocarbons by hydrogenation was used in the production of light olefins.Hy-drothermal coating and physical blending procedures were used to synthesize Y2O3/Fe-Co-SAPO-34 in this study.Based on the results from characterization,a unique micro-mesoporous structural composite with co-existing basic and acidic sites was obtained without any excessive close-fitting between the active sites in the physically blended composite.The catalyst's overall selectivity for the light olefins was 82.6% with CO2 conversion of 19.9% for H2/CO2 of 3.0,with space velocity of 10 L.g.cat~(-1)h~(-1)at 400 ℃ and 20 bars.Furthermore,an increase in the number of acidic-basic sites,meso-microporous structures,alongside the synergetic effects of the com-positephases over the catalyst without any support,improved the catalyst's activity for CO2 conversion which in turn yielded higher C_2~=-C_4~= selectivity.The hybrid catalyst had a commendable stability within 80-hours of operation without losing its activity
