Hydrogen production from methane with CO2 utilization over exsolution derived NiCu/CeO2 catalysts was studied. To form highly dispersed supported bimetallic NiCu particles the Ce0.75(NiCu)0.25O1.75 catalyst precursors (Cu/Ni molar ratio=0; 0.004; 0.04; 0.25) were prepared by polymerizable complex method with the following reduction at 800 °C. A comparative study of the genesis, textural, structural and morphological properties of materials has been carried out by ex situ and in situ methods. It was shown that Ce0.75(NiCu)0.25O1.75 samples were fuorite-like ceria-based solid solutions with a mesoporous texture. Copper promotion has a positive efect on self-activation and hydrogen yield by improving the reducibility of the catalyst, lowering the exsolution temperature of the Ni2+ cations, and maintaining the concentration of oxygen vacancies. The catalyst of optimal composition NiCu/CeO2 (9.4 wt. % Ni, 0.4 wt. % Cu) formed from Ce0.75(NiCu)0.25O1.75 with Cu/Ni=0.04 is resistant to coking and provides high hydrogen yield (82%) and CO2 utilization (78%) in steam/CO2 reforming of methane at 850 °C
