MoS2 nano-platelets were deposited on TiO2 by acidifying the mixed solution of Na2S and Na2MoO4.The photocatalytic properties of the obtained MoS2/TiO2 composite was studied using the degradation reaction of methyl red.The results showed that the composite catalyst had excellent photocatalytic properties.The degradation reaction of methyl red was influenced by the amount of catalyst,initial concentration of methyl,and pH value of methyl solution.The decoloration percent of methyl red was about 65 % within two hours reaction in the 3-time reusing of the composite catalyst,indicating that the synthesized catalyst was of good reusing performances.
