GOLD CATALYSTS SUPPORTED ON MIXED OXIDES HIGHLY EFFICIENT AND STABLE IN THE WATER GAS SHIFT REACTION

CSIC, in collaboration with the University of Seville, has developed the synthesis of gold catalysts highly efficient in the Water Gas Shift Reaction (WGS). The catalysts, based on gold supported on CuO/ZnO/Al2O3 mixed oxides with hydrotalcite structure, are able to work without any pre-treatment and are robust against changes in the reaction operation conditions, that make them very useful for production and/or H2 purification processes for fuel processors coupled to fuel cells.
