摘要： Ag/g-Al2O3 is a kind of promising catalyst with the relatively lower cost compared with those using noble metals, good resistance against catalytic poisoning and excellent behaviour for NOx removal. In the present study, Ag/g-Al2O3 catalysts were synthesized by the solvothermal process and characterized by XRD, TG-DTA, TEM, UV-Vis and FT-IR. It was found that high-performance Ag/g-Al2O3 catalysts could be synthesized by properly selecting starting materials, controlling the composition of solvent and other reaction conditions. The microstructure evolution of the catalysts was also discussed.
