Description
技术领域
本发明涉及环境污染控制新材料领域，尤其涉及一种氧化锌复合磷酸钇催化剂的制备方法。
背景技术
随着科技的发展，来自工农业生产中产生的毒害有机污染物严重威胁着环境和人类的健康，寻求一种新型高效的环境治理技术具有重要的意义。光催化技术因其节能、高效、污染物降解彻底、无二次污染优点，目前已成为一种具有重要应用前景的新兴环境治理技术。近年来，新型高效的可见光光催化剂的研制成为光催化技术中的一个重要研究内容，其中具有表面等离子共振效应的光催化材料，因其独特的表面物理化学性质和高效的可见光光催化性能，成为研究的热点之一。
然而，目前所报道的可见光光催化材料大多具有较高的光生载流子复合率和较差的可见光吸收，导致其量子效率较低。因此，开发新型高效可见光光催化材料，拓展半导体材料光谱响应范围以及促进光生电子和空穴有效分离，成为目前光催化材料研究领域急需解决的科学问题。
发明内容
本发明的目的是为克服现有技术中光催化降解污染物过程中的不足，提供一种氧化锌复合磷酸钇催化剂的制备方法。
为此，本发明提供了以下技术方案，一种氧化锌复合磷酸钇催化剂的制备方法，依次包括如下步骤：
在60～80℃水浴下，向5～10mL浓度为0.1～0.5mol/L的硝酸钇溶液中边搅拌边滴加10～15mL浓度为0.02～0.08mol/L磷酸氢二钠溶液，搅拌2～4h后，制得磷酸钇小颗粒悬浊液，继续向其中加入0.3～1mmol氯化锌固体，提高水浴温度至90～100℃，搅拌2-3h，固液分离，将固体用去离子水洗涤3～5遍，在105℃下烘干；将烘干得到的产品在400～600℃下煅烧5～8h，即可得到一种氧化锌复合磷酸钇催化剂。
与传统催化剂相比，本发明具有以下优越性：首先形成磷酸钇颗粒，然后在后续过程中形成氢氧化锌胶体颗粒附着于磷酸钇表面，形成均匀的复合体。所制得的催化剂有较好的晶体结构且有较大的比表面积，稳定，光降解处理效率高。
