通过高温高压法,利用高压釜装置一步合成Al-交联剂,通过离子交换法制备大比表面积、大孔径的Al柱撑粘土(Al-PILC).研究了稀土铈改性的Al-PILC负载锰氧化物用于氯苯的催化降解的活性.表征结果表明:柱撑后得到的Al-PILC,其比表面积和孔体积达到182.3m2·g-1和0.121 cm3·g-1,远大于原土的2.81 m2·g-1和0.00786 cm3·g-1.Al-PILC的层间距由原土的1.18增大到1.79nm.活性数据表明:柱撑改性后的Al-PILC负载锰催化剂的活性远大于Na-mmt的,并且添加稀土Ce有利于改善催化剂的氧化性能,进而提高催化剂的活性.10％ Mn-6％Ce/Al-PILC催化剂在330℃左右就能催化降解低浓度的氯苯,无Cl2二次污染产生,并且表现出最佳的稳定性.
