Effect of sintering temperature on the electrolysis of TiO2Ze-quan Li 1,2) , Li-yue Ru 1) , Cheng-guang Bai 2) , Na Zhang 1) , and Hai-hua Wang 1) 1) College of Chemistry and Chemical Engineering... migration, so a lower sintering temperature was favorable for the microstructure of electrolysis. Consequently, the cathodic conductivity may be improved, but the microstructure became compact......
