degradation of different dyes in an aqueous solution under visible light irradiation. According to the literature test method [ 3 ], a 300-W tungsten lamp was positioned inside a cylindrical Pyrex vessel surrounded by a circulating cooling water jacket and a

air, D A , was taken from the literature (0.0804 cm 2 s −1 ) [ 37 ]. All computations were performed only with one estimated parameter, e.g. reaction rate constant, k A , in order to avoid uncertainty due to a great number of parameters. Parameter

]. Moreover, isomerization of 1-butene to 2-butenes increased as shown by an increase of the ratio between 2-butenes and 1-butene to 4. There has been a well established trend in the literature that the 1,3-butadiene hydrogenation rate increases with

, the values for CoTNPP–PVI/SiO 2 , CoTClPP–PVI/SiO 2 , FeTPP–PVI/SiO 2 and MnTPP–PVI/SiO 2 were 33.4, 28.7, 23 and 20%, in order. So the maximum yield of acetophenone reached 33.4%, which is larger than that in the literature [ 24 ]. In summary, under
