| Abstract: | Crystalline phase,surface and pore structure of copper-based ultrafine particle catalysts prepared by sol-gel method were studied by BET and TEM techniques respectively.The influential factors of preparation of copper-based catalysts and especially catalysts' stability and paticals' diameter effected by different molecular weight of polypropyleneacid dispersants were also studied.The results show that the catalysts have the characters of high catalytic activities and low copper iron leaching in wastewater treatment by CWAO.The catalysts would have apromising application. |
| Keywords: | sol-gel copper iron leaching catalytic wet air oxidation wastewater treatment |
