Method for preparing nano-grade rutile phase RuO2-SnO2 oxide

Abstract

The invention provides a method of preparing a full nanometer grade rutile titanic phase RuO2-SnO2 oxide, which uses RuCl3, SnCl2 and SnCl4 as precursors. The ratio of RuO2 to SnO2 in a titanium anode coating prepared by the invention is 1 to 4 to 4 to 1. The surface coating of the titanium substrate is made from the full nanometer grade rutile titanic phase RuO2-SnO2 oxide or solid solution. Thespecific surface area is larger than 460m<2> question mark g<-1>. And raw materials are easy to be obtained, and the method is simple.

Description

technical field The invention belongs to the field of electrochemistry, and more specifically relates to a nanoscale rutile phase RuO 2 -SnO 2 Oxide preparation method. Background technique Noble metal oxide RuO 2 It is an n-type semiconductor rutile oxide with a rutile structure. It is an important functional material because of its high catalytic activity and corrosion resistance. It is widely used in electrochemical industry, chemical industry and electronic industry. Especially the recent nanoscale RuO 2 The demand in the high-tech field is increasing, which makes its price rise sharply in the international market. SnO 2 It is an n-type semiconductor rutile oxide with the same structure, and its ionic radius is similar to that of RuO. 2 The characteristics of mutual solid solution. plus SnO 2 It is not easy to oxidize, can refine grains, and can improve the stability of active elements, so it can be used as a noble metal oxide RuO 2 Adding materials to obtain f...

Problems solved by technology

Therefore, it is quite difficult to promote the technology of this preparation method.

Although the sol-gel method is considered to be the most promising preparation method, the overall performance of the prepared titanium anode is still not ideal
