Abstract: Cu-HKUST-1 was prepared by a solvothermal method using copper nitrate and trimesic acid.Then a series of Cu/Cu2O/CuO ternary copper-based composite catalysts were prepared by sintering Cu-HKUST-1 under different atmospheres.By changing the proportion of nitrogen and oxygen in annealing gas,the content of Cu,Cu2O and CuO in Cu/Cu2O/CuO catalysts can be effectively adjusted.The results showed that Cu,Cu2O and CuO in catalysts can be rationally modulated,i.e.,the trace increase of air in annealing stream can lead to the decreasing of Cu,whereas the content of Cu2O and CuO increased.The optimization of Cu,Cu2O and CuO can be realized by adjusting the annealing atmosphere.In the catalytic reduction of p-nitrophenol,the optimized Cu/Cu2O/CuO catalysts (N2∶Air=200mL∶2mL) exhibited the highest catalytic activity and it took 45s to obtain a conversion rate of above 90%.
