文摘
Ce/N co-doped TiO2/diatomite granule (CNTD-G) was prepared via sol-gel method. The optimal doping amount of Ce was determined. The effects of impurity ions on photodegradation process were studied. The intermediates generated during photodegradation process were deduced. The mechanism of photodegradation process was proposed.
