The water-gas shift (WGS) reaction (CO + H2O = CO2 + H2, ΔH= -41.1 kJ/mol) and its catalyst (CuZnO-based catalyst for a low-temperature stage and FeCr-based catalyst for a high-temperature WGS reaction stage) are well established in industrial operations such as ammonia and hydrogen production plants. The WGS reaction, especially a single stage WGS reaction at a medium temperature range, has been reobtained worldwide attention due to its application in clean power generation systems in recent years. In this study, the series of Ti modified Pt/ZrO2 catalyst was prepared for a single stage WGS reaction to enhance the catalytic activity and the Ti addition effect has been investigated on the reducibility and WGS reaction performance of Pt/ZrO2. |
