Effects of M-promoter (M=Y, Co, La, Zn) on Cr2O3 catalysts for fluorination of perchloroethylene

The conversion of PCE is 90.6% and selectivity to effective product is 93.7% at 300°C over La-Cr2O3(F) catalyst. •Promoter M (M=Y, Co, La, Zn) can change the catalytic performance of Cr2O3 catalyst.•La-Cr2O3(F) catalyst exhibited the highest activity and selectivity and it showed a good reaction sta...
