Description
技术领域
本发明涉及光催化技术领域,特别涉及一种金属有机骨架担载纳米钒酸铋催化剂及其制备方法。
背景技术
以太阳能为能源,利用光催化技术,实现光催化产氢和有机污染物降解是解决当前日益严重的环境污染和能源危机的一条有效途径。钒酸铋是一种具有可见光响应的新型光催化剂,它是一种典型的层状结构半导体,具有一系列诸如窄带隙、稳定性高、无毒、可反复使用等优异的性质,因此受到人们的广泛关注。但是,由于纯钒酸铋空穴扩散距离较短且表面反应动力学较慢,极易发生电子-空穴复合现象,造成量子转换效率低,不利于其在光催化反应中的应用。
通过将其它材料与钒酸铋复合,构筑钒酸铋复合光催化剂,可显著增强钒酸铋光催化剂的光催化性能。专利C201810329038.1公开了一种硫化铜/钒酸铋双层膜复合材料的制备及作为光电阳极的应用,该专利采用简单的滴涂法将硫化铜负载于钒酸铋电极上,得到硫化铜/钒酸铋双层膜复合材料。这种材料有助于光生载流子的快速分离,从而提高了钒酸铋的光电化学性能。专利CN201810233687.1公开了一种钒酸铋插层氧化石墨烯可见光催化功能织物的制备方法,该专利预先用氧化石墨烯改性织物,随后在改性织物上沉积钒酸铋,得到具有高可见光催化净化效果的功能织物。但是目前,钒酸铋复合材料的比表面积较小,其物理吸附作用较差,同时光生载流子对的复合率仍然偏高,使该材料的使用存在一定的局限性。
发明内容
本发明的目的在于提供一种镍金属有机骨架担载纳米钒酸铋催化剂及其制备方法,该催化剂载体为镍金属有机骨架,活性担载物为具有表面氧缺陷位的纳米钒酸铋。该催化剂是通过预先制备镍金属有机骨架,然后在镍金属有机骨架上沉积纳米钒酸铋,最后置于还原性气氛经部分还原而制得。所述镍金属有机骨架的有机配体为芳香族二元羧酸及其衍生物。该催化剂具有较高的光催化反应活性和稳定性,在污水处理、光能转换等领域有较大的应用前景。
为了达到上述目的,本发明是通过以下技术方案实现的:
(1)室温下,按二甲基甲酰胺与去离子水的质量比10:1~20:1,配置二甲基甲酰胺水溶液,按无水乙醇与去离子水的质量比0.5:1~2:1,加入无水乙醇,搅拌10~30 min,按有机配体与二甲基甲酰胺的质量比0.005:1~0.02:1,加入有机配体,再按镍盐与有机配体的质量比1:1~2:1,加入镍盐,搅拌30~60min,再按三乙胺与二甲基甲酰胺的质量比0.01:1~0.05:1,加入三乙胺,搅拌,20~80℃下反应5~12h,离心分离,沉淀用5~10倍二甲基甲酰胺质量的乙醇洗涤,70~100℃下干燥6~12h,得镍金属有机骨架;
(2)室温下,按铋盐与去离子水的质量比0.02:1~0.1:1,配置铋盐水溶液,按镍金属有机骨架与铋盐的质量比2:1~10:1,加入镍金属有机骨架,再按偏钒酸盐与铋盐的质量比0.1:1~0.5:1,加入偏钒酸盐,搅拌10~30 min,用质量分数为2%~5%的无机碱水溶液调节混合溶液的pH至4~7,转移至反应釜中,100~200℃反应8~16h,冷却至室温,离心分离,沉淀依次用10~50倍镍金属有机骨架质量的去离子水和乙醇洗涤,60~80℃下真空干燥8~12h,得镍金属有机骨架担载纳米钒酸铋初产物;
(3)将镍金属有机骨架担载纳米钒酸铋初产物放入管式炉中,通入还原性气体,控制气体流量为10~40mL/min,于200~350℃下反应2~6h,自然冷却至室温,得镍金属有机骨架担载纳米钒酸铋催化剂。
上述制备方法中,所述的有机配体为对苯二甲酸二甲酯、对苯二甲酸中的一种。所述的镍盐为六水合氯化镍、六水合硝酸镍中的一种。所述的铋盐为五水合硝酸铋、氯化铋中的一种。所述的偏钒酸盐为偏钒酸铵、偏钒酸钾、偏钒酸钠中的一种。所述的还原性气体为高纯氢或氢气体积分数为5~20%的氢氩混合气。
本发明的特点如下:
(1)利用还原性气体在纳米钒酸铋表面进行部分还原,产生表面氧空位缺陷,增加催化剂的活性位点数量,促进了催化剂对可见光的利用效果,有助于提高催化剂的催化活性。
(2)钒酸铋与镍金属有机骨架间存在的强协同效应,可以提高光催化过程中光生电子-空穴的转移效率,从而有利于提升催化剂的催化活性。
(3)将纳米钒酸铋担载于镍金属有机骨架上可显著抑制纳米钒酸铋颗粒的团聚,进而提高催化剂的稳定性,同时镍金属有机骨架的多孔结构和高比表面积可以促进催化剂对反应介质的吸附效果,并为反应介质提供更好的扩散途径,有利于促进催化反应的进行,进而提高催化剂的催化活性。
