以抗坏血酸为还原剂、燃烧剂,硝酸铜为氧化剂,燃烧法快速合成铜的氧化物.通过改变燃烧剂的用量制备氧化铜、氧化铜与氧化亚铜的复合氧化物和氧化亚铜.对所制样品进行XRD、电镜表征.改变燃烧剂与硝酸铜的摩尔比制备出铜的不同氧化物,其形貌也各不相同.以氧化铜与氧化亚铜的复合氧化物为催化剂,甲基蓝溶液为污染物进行光催化实验,同时对光催化条件进行考察:pH值、催化剂用量、双氧水用量、时间等条件对光催化的影响,得出氧化铜与氧化亚铜的复合氧化物的光催化条件为:pH=7,催化剂用量为0.6 g/L,时间为90 min.
Ascorbic acid as reductant, combustion agent, copper nitrate as oxidant, combustion method for the rapid synthesis of copper oxide by changing the amount of combustion agent prepared copper oxide, copper oxide and cuprous oxide composite oxide and cuprous oxide. The samples were characterized by XRD and SEM.The different oxides of copper were prepared by changing the molar ratio of the combustion agent to copper nitrate.The morphologies of the samples were also different.Using the composite oxides of copper oxide and cuprous oxide as catalyst, Solution as pollutants for photocatalytic experiments, while the photocatalytic conditions were investigated: the pH, the amount of catalyst, the amount of hydrogen peroxide, time and other conditions on the photocatalytic effect of copper oxide obtained with the cuprous oxide composite oxide photocatalyst The conditions were: pH = 7, catalyst dosage 0.6 g / L, time 90 min.
