Description

一种光催化剂的配制方法
技术领域:
本发明涉及一种化工产品,具体涉及一种光催化剂的配制方法。
背景技术:
光催化剂是近年来兴起的一种对环境治理极有效的复合材料,生产方法历经硫酸钛法、四氯化钛法、钛脂法等过程。材料应用由钛到钛载银,时间跨度大、生产工艺复杂、进展速度慢,且由于上述纳米材料因需要强烈的紫外线照射,才能激活材料起氧化还原反应,因此很大范围上限制了光催化剂的应用范围。
发明内容:
本发明的目的是根据上述不足之处而研制一种光催化剂的配制方法,按照本发明的方法生产出的光催化剂在无光或弱光的条件下,依靠热能,使光催化剂电子产生转移,激活材料本身,产生氧化还原作用,从而扩大光催化剂应用范围,增强光催化剂的性能。根据中国科学院理化研究所的检测,中国广州微生物研究所的检测,依照本发明的方法生产的光催化剂,在无光或弱光条件下,抗菌率达99.99%,分解苯和甲醛的能力为88.6%和76.5,达到相当高的数值。
本发明的光催化剂的配制方法是这样实现的。
该发明的光催化剂是在氧化中心元素银和电子容纳元素钛的基础,增加电子供给元素钼和钨、还原元素钯、氧化活性剂锂、还原活性剂锆、电子转移元素锰,从而使光催化剂各部份功能完备,氧化还原能力大大增强。在黑暗状态,依靠大气热能,照常发挥作用,除臭、杀菌、防污能力增强。
本发明的光催化剂的配制方法如下:按重量百分比。
配方:
载体水       50-70%    钼    2-3%
醇溶剂       10-15%    锆    0.5-1%
钛           10-20%    锰    0.5-1%.
银           1.5-2%    锂    2-3%
钯           1.5-2%    铑    2-3%
本发明的工艺是将上述金属元素及半导体材料,以金属盐的形态流入溶剂和载体水中,按纳米材料水溶液法生产,最后获得纳米级新型光催化剂。
本发明生产出的光催化剂是在无光或弱光的条件下,依靠热能,使光催化剂电子产生转移,激活材料本身,产生氧化还原。从而扩大光催化剂应用范围,增强光催化的性能。经中国科学院理化技术研究所抗菌材料检测中心与广东省微生物分析检测中心检测,其效果,抗菌率达99.9%,分解苯和甲醛的能力为88.6%和76.5%,效果显著地解决建筑装饰材料中抗菌灭菌,分解和清除苯与甲醛的难题,大到安全环保,造福于人民的目的。
