GamCrOx/H-SAPO-34(F), a highly efficient bifunctional catalyst for the direct conversion of CO2 into ethene and propene

Adding Ga in GamCrOx can regulate the adsorption and activation of CO2 and H2, whereas adding HF during synthesis can modulate the acidity of H-SAPO-34 (nF). The Ga0.15CrOx/H-SAPO-34(0.5/1.0 F) composite exhibits excellent performance in the direct hydrogenation of CO2 to light olefins.
