Abstract:
1. A method for making a metal/titania pulp, comprising: mixing a titanium alkoxide and an alcohol solvent to obtain a titanium alkoxide solution, dripping the mixed titanium alkoxide solution at about two drops per second and a 47 ml/hour dripping rate and stirring at a constant rate in an ice bath at a temperature of 3 to 10° C., and acidically hydrolyzing the titanium alkoxide solution under nitrogen atmosphere to get a hydrolyzed solution; standing the hydrolyzed solution at a temperature of 60 to 100° C. for 2 to 6 hours to obtain a titania colloidal solution; adding at least one metal salt compound into the titania colloidal solution to form a mixed pulp; and subjecting the mixed pulp to a thermal treatment process to get a titania pulp.
