| 内容記述 | Results are presented of surface characterization of 2% and 1% (w/w) Pt on SnO2 catalysts which are being used in promoting the oxidation of CO in pulsed CO2 lasers. The N2 adsorption BET surface area for both catalysts is 6.9 sq m/g. The CO chemisorbed area at 313K is 0.17 sq m/g and 0.062 sq m/g for the 2% and 1% catalysts, respectively. Monitoring the reaction between CO and O2 by the same technique, at the same temperature yields a turn-over frequency (TOF) for the 2% catalyst of 2.7 x 100 molecules of CO2/site/s and for the 1% catalyst a value of 1.2 x 100. The ratio of the TOFs for the two catalysts is 2.2 which is approximately the ratio of the Pt loading. |
