Abstract：

In　this　paper,　two　kinds　of　CNT/TiO2　composites　were　synthesized　by　different　sol-gel　methods.　Comparing　to　the　TiO2　/CNTs　prepared　by　method　1　(Tetrabutyl　titanate+CNT,　H2O),　the　catalysts　synthesized　by　method　2　(Tetrabutyl　titanate,　CNT+H2O)　showed　higher　photocatalytic　activity　and　the　optimum　content　of　CNT　was　1%.　Furthermore,　diverse　reactors　were　introduced　to　deal　with　methyl　orange　and　phenol　wastewater.　Coniform　reactor　was　found　as　the　optimum　reactor　for　its　direct　irradiation　and　high　ultrasonic　enegy　efficiency.　Sono-photocatalytic　degradation　is　not　only　affected　by　the　type　of　catalyst　and　reactor,　but　also　can　be　affected　by　the　species　of　the　contamination.　©　2011　IEEE.
