一种金属离子掺杂二氧化钛光催化剂的制备方法
摘要：
一种金属离子掺杂二氧化钛光催化剂的制备方法，首先取20ml HNO3溶液并向其中加入金属硝酸盐得到溶液A；其次，将溶液A置于磁力搅拌器上加热搅拌，待溶液挥发至15ml时，将钛酸四正丁酯溶解在溶液A中，继续加热并搅拌直至得到金属离子掺杂TiO2晶体；最后，将金属离子掺杂TiO2晶体置于研钵中研细，然后，于马弗炉中烧结，炉中自然冷却至室温得到金属离子掺杂二氧化钛光催化剂。本发明利用均匀热水解法制备掺杂金属离子的TiO2，将所需原料配制成溶液，使原料在离子水平上非常均匀的进行混合，所得的金属离子掺杂二氧化钛光催化剂扩大对太阳光的吸收范围，提高光催化活性，同时增强抗菌效果。
摘要（英）：

The invention relates to a preparation method of a titanium dioxide photocatalyst doped with metal ions. The preparation method comprises the following steps of: firstly, taking 20ml HNO3 solution and adding metal nitrate into the solution to obtain solution A; secondarily, putting the solution A on a magnetic stirrer for heating and stirring, when the solution volatiles to 15ml, dissolving tetrabutyl titanate into the solution A, continuously heating, stirring till TiO2 crystal doped with metal ions is obtained; finally, putting the TiO2 crystal doped with metal ions into a mortar for porphyrization, then sintering in a muffle furnace, naturally cooling the furnace to room temperature and obtaining the titanium dioxide photocatalyst doped with metal ions. The invention utilizes a uniformpyrohydrolysis method to prepare TiO2 doped with metal ions and prepares the needed raw materials into solution, leads the raw materials to be mixed uniformly on ion; and the obtained titanium dioxide photocatalyst doped with metal ions expands the absorption range to sunlight, improves photocatalytic activity and simultaneously enhances antibacterial effect.
