矿物催化剂

随着工农业的发展，废水排放量越来越多，中国2015年废水排放量高达735.3亿吨，废水主要包含有机污染物(例如罗丹明B(RhB)、亚甲基蓝(MB)、酸性橙7(AO7)、4氯酚(4-CP)、四环素(TC))和重金属(例如Cr(VI))，严重威胁人类健康。为了降解这些污染物，光催化技术以其一系列的优点(低毒性、易操作、反应条件温和等)引起广泛关注。光催化技术最重要的是开发高效且易回收的光催化剂。传统粉末状光催化剂展现较高的催化活性，但是回收利用困难，易造成二次污染，限制了在流动废水处理中的应用。为了解决这一问题，我们以碳纤维布为基底，表面生长C3N4基半导体异质结，构建多种宏观面积大、柔性好、催化活性高的滤膜状光催化剂。With the development of industrial and agricultural activities, the volume of wastewater discharge has been growing continuously. In 2015, China's total wastewater discharge reached 73.53 billion tons. The wastewater mainly contains organic pollutants such as rhodamine B (RhB), methylene blue (MB), acid orange 7 (AO7), 4-chlorophenol (4-CP), and tetracycline (TC), as well as heavy metals like hexavalent chromium [Cr(VI)], posing a severe threat to human health. To degrade these pollutants, photocatalytic technology has attracted widespread research attention due to its multiple advantages including low toxicity, simple operation, and mild reaction conditions. The most critical priority for advancing photocatalytic technology is to develop efficient and readily recyclable photocatalysts. Conventional powdered photocatalysts exhibit high catalytic activity, but they are difficult to recycle and prone to causing secondary pollution, which restricts their application in flowing wastewater treatment. To solve this problem, we used carbon fiber cloth as the substrate, grew C3N4-based semiconductor heterojunctions on its surface, and fabricated a series of filter-membrane-like photocatalysts with large macroscopic area, excellent flexibility, and high catalytic activity.
