本发明提供的光催化材料是炭黑磷酸银复合光催化材料。
本发明提供的炭黑磷酸银复合光催化材料的制备方法如下：
将一定量的银盐溶于一定浓度的炭黑水溶液中。再将一定量的可溶性磷酸盐水溶液缓慢的加入到银盐的溶液中，得到的沉淀洗涤干燥后获得催化材料。
光催化活性测试方法：
光催化材料的活性测试是在自制的立式石英反应器中进行的。采用300W氙灯(λ＞400nm)为辐射光源，反应液为100mL 20-40mg/L的甲基橙水溶液，催化剂的浓度为1g/L。以20mL/min的速率鼓入空气泡，在持续的搅拌下每隔2min抽取少量反应液，在463nm处测定溶液吸光度。再根据甲基橙的浓度-吸光度标准曲线确定溶液浓度。
具体实施方案
实施方案1
将0.5g硝酸银溶于20mL 1mg/L的炭黑溶液中，将2g磷酸铵溶于10ml去离子水中，在搅拌下将磷酸铵溶液滴加入硝酸银的溶液中，得到的沉淀抽滤，依次用蒸馏水和无水乙醇洗涤，然后80℃真空干燥6h得到相应的光催化材料。
实施方案2
将实施方案1中的磷酸铵换为磷酸二氢钠，其它条件不变。
实施方案3
将实施方案1中1mg/L的炭黑溶液变为1.5mg/L，其它条件不变。
实施方案4
将实施方案1中1mg/L的炭黑溶液变为2mg/L，其它条件不变。
实施方案5
将实施方案1中1mg/L的炭黑溶液变为3mg/L，其它条件不变。
