比较了两种载铂方法。用光浸渍与氢还原联合的方法可得到铂含量较高、铂分布较均匀和催化活性较好的Pt/TiO_2光催化剂。采用电化学方法研究了TiO_2粉末表面联合法载铂的机理。
Two methods of platinum loading were compared. The combined Pt / TiO_2 photocatalyst with higher content of platinum, more uniform distribution of platinum and better catalytic activity can be obtained by the combination of photoimpregnation and hydrogen reduction. The electrochemical method was used to study the mechanism of the combined loading of TiO2 on the surface of TiO2 powders.
