担载CuO基催化剂上2,4-二氯酚的有效氧化降解
DOI: 10.3724/SP.J.1088.2011.10334, PP. 1387-1392
Keywords: 氧化铜,氧化铝,负载型催化剂,碱土金属氧化物,2,4-二氯酚,氧化降解
Abstract:
？研究了2,4-二氯酚的催化氧化降解.结果表明,CuO/γ-Al2O3催化剂表现出较高的活性,且碱土金属氧化物助剂的添加可进一步显著提高2,4-二氯酚氯离子的释放率,其中以SrO的促进作用最强,该催化剂循环使用3次,2,4-二氯酚转化率及氯离子的释放率均维持100%.X射线衍射和NH3程序升温脱附结果表明,催化剂上CuO粒子分散度高并且酸中心数少有利于2,4-二氯酚的氧化降解.提出了2,4-二氯酚催化氧化降解可能的反应途径.
