Effect of various adhesive agent on the performance of Pt/SnO2 CO2 laser catalyst

With silicasol,alumina hydrogel,polyethylene glycol,nitric acid,etc,as adhesive agents while catalyst forming,Pt/SnO2 catalyst used in closed CO2 laser is prepared.The effect of adhesive agents on physical characters and activity of catalyst for CO oxidation are investigated.It is concluded that the conversion of CO on the Pt/SnO2 catalyst which is prepared by containing silica-base adhesion agent is 100% at room temperature of -20℃ as well as space velocity of 1×104h-1.The catalyst still has an excellent activity for CO oxidation at -35℃.
