WANGPeng-hua (1.SchoolofChemistryandChemicalEngineering, Guang ~ thonUniversity, Guangzhou510006, China; 2.SchoolofChemistryandChemicalEngineering, GuangxiUniversity, Nanning530004, China) Abstract: Inthispaper, usingthesemiconductorcatalystMoO3andphotosensitizeracetoneonphotocatalyticdegradationofmethylorangeanditskineticswereinvestigated. ThesemiconductorcatalystMoO3performanceshowedgoodeffectandphotocatalyticdegradationconstantratewas10.31mg · L ~ · ml'n ~. Addingtracequantityofphotosensitizeracetonesimultaneously, degradationrateofmethylorangeonMoO3catalystswasin-creased. UnderMoO3catalysisandtheacetoneph0t0sensitizati0n, arateequationofr = 2.33-0.14t 0.024t +0.0026 t a a 9 × 10 a a t t +1 × 10 for a 6x10 one tforphotocatalyticreactionwasobtained.
