A 1%Ni/SBA-15(P) catalyst was synthesized with a P123-assisted impregnation method, which exhibited high CO2 conversion and stability in the reverse water-gas shift reaction. For catalyst, TEM TPR characterizations demonstrated that highly dispersed NiO particles at about 3 nm strongly interacted SiO2 support. During reaction, higher than 1%Ni/SBA-15 prepared by conventional method without P123...

This communication describes the fabrication of Pt/CeO2 nanotube@SiO2 core-shell catalysts applied to highly efficient water-gas shift reaction, where the initial CO conversion is 30.2% at 250 °C. Pt/CeO2 nanotube@SiO2 core-shell catalysts show outstanding thermal stability, even after accelerated aging under reaction conditions at 450 °C for 6 h, and the morphology is also unchanged after ther...
