- W2022989493 abstract "Coprecipitated SnO2CuO gels are active catalysts for the low-temperature (ambient-100 °C) steady state oxidation of carbon monoxide after thermal activation at temperatures up to 450 °C. Using the described method of preparation maximum catalytic activity occurs at a Cu:Sn atomic ratio of ~0.55:1, and evidence from pH-titration, thermal analysis, and X-ray data suggests that this activity is a consequence of the ion-exchange sorption of Cu(II) ions on the surface of primary hydrous SnO2 particles formed during the precipitation process. X-Ray data on SnO2CuO gels show no evidence for the formation of a mixed oxide compound or solid solution after calcination at temperatures up to 1000 °C. Steady state CO oxidation at 70 °C on 450 °C-activated SnO2 · 0.55CuO obeys the empirical rate equation: d(CO2)/dt ∝ pCO0.43p O20.10/pCO20.37" @default.
