技术领域
本发明涉及一种新型光催化材料。
本发明还涉及上述光催化材料的制备方法。
本发明还涉及上述光催化材料的用途。
背景技术
光催化属于物理化学的边缘学科，最近几年发展态势呈活跃的递增状，有着重要的应用前景。目前已应用于众多领域，如无机化学、分析化学、有机化学、生命科学、材料科学、能源科学、信息科学、环境科学等等。光催化不仅可以光解水生成氢气和氧气这些清洁能源，也能降解有机物使其分解为对环境相对无毒无害的无机物，因此而备受青睐。朱明山等人研究发现银/卤化银(Ag/AgCl，Ag/AgBr和Ag/AgI)等离子体型光催化剂对有机污染物的光降解表现出了高效性能，且该类催化剂具有良好的光化学稳定性。虽然氯化银具有很多光催化材料的特有优势，比如：能够大量吸收可见光、容易改性提高其氧化能力、能够降解多种有机污染物等。但是其本身也有很多弱点，比如怕酸，稳定性差等等。本发明针对大幅提高氯化银的光催化氧化能力，提高其稳定能力，设计合成了锑掺杂Ag/AgCl光催化材料催化剂，旨在提高其活性和稳定性。
发明内容
本发明的意义在于提供一种高效稳定的新型光催化材料，这种光催化材料能够被可见光激发，并且有非常好的光催化降解有机物质的活性，同时制备过程简便、成本很低。
本发明提供的光催化材料是钴改性磷酸银粒子。
本发明提供的钴改性磷酸银光催化材料的制备方法如下：
将一定量的的三氯化锑溶解在一定量的稀盐酸中，制备出银氨溶液，将一定量的三氯化锑溶解在25mL，1mol/L的稀盐酸中，添加入上述溶液，其中，锑在Ag/AgCl催化剂中占质量分数为2wt.％.。保持均匀搅拌60min，使其反应充分，生成的白色沉淀用去离子水洗至中性，离心(3000r/min)数次，放入烘箱中，80℃烘干催化剂
在可见光辐射下降解甲基橙的光催化活性测试具体方法和条件如下：
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
称取0.36g硝酸银，溶解于3.9mL浓氨水中，用去离子水稀释至25mL，保持均匀搅拌20min，制备出银氨溶液，将一定量的三氯化锑溶解在25mL，1mol/L的稀盐酸中，添加入上述溶液，其中，锑在Ag/AgCl催化剂中占质量分数分别为1wt.％，2wt.％，3wt.％和5wt.％。保持均匀搅拌60min，使其反应充分，生成的白色沉淀用去离子水洗至中性，离心(3000r/min)数次，放入烘箱中，80℃烘干催化剂。
实施方案2
将实施方案1中的硝酸银换为氯化银，其它条件不变。
