Fe^(3+),Y^(3+)掺杂对TiO_2粒子自然光催化降解甲基橙效果的影响

The Doping Effect of Yttrium and Ferric on the Degradation of Methyl Orange by Solar Ray Photocatalysis with Titania

以钛酸丁脂和FeCl3 ,YCl3 为原料 ,采用溶胶 凝胶法制备Y3 ,Fe3 +掺杂的TiO2 粒子 ,并研究了TiO2 颗粒在自然光下催化降解甲基橙的情况 ,通过催化实验表明 :适量的Fe3 +和Y3 +的掺杂均能提高TiO2 粒子的自然光催化降解能力 ,适量的Fe3 +和Y3 +的混合掺杂能进一步提高TiO2

Effect of Yttrium and ferric doping on solar ray photocatalytic properties of titania particles to photoreduetion of methyl orange abstract: in this paper, the yttrium and ferric doped titania particles were synthesis from YCl3 and FeCl3 by sol-gel method and their solar ray photocatalysis characteristics to photoreduction of methyl orange had been srudied, the results show that the photocatalvtic actiritles of yttrium and ferric doped titania particles were more higher than that of pure titania particle.
