Author

Abstract

The properties of supports have a significant effect on the activity of noble metal single atoms. In this work, Co-doped CeO2-supported single-atom Pt catalysts (Pt1/Co-CeO2) have been acquired by a synchronous pyrolysis/deposition route and demonstrated to promote low-temperature oxidation of CO. Revealed by a model reaction of 1% CO + 1% O2+ 98% He at a space velocity of 12,000 mL/gcat/h, CO conversion (100 °C) acquired on a (0.5% Pt)/(10% Co-CeO2) catalyst (36.6%) was 3.6 and 4.9 times those of 0.5% Pt/CeO2(10.0%) and 10% Co-CeO2(7.4%) catalysts and 2.1 times that of their conversion sum (17.4%), confirming the positive role of the Co dopant in boosting the low-temperature oxidation of CO. The consistent results are also verified in the comparison of Pt1/Co-ZnO with Pt1/ZnO and Pt1/Co-Al2O3with Pt1/Al2O3. In addition, the activity of single-atom Pt1/Co-CeO2catalysts can be facilely modified by changing the loading of Pt and/or doping amount of Co. These reasonable data will provide a methodology to access more applicable catalysts for CO oxidation at low temperature.

Abstract

As a clean and renewable energy source, hydropower benefits the sustainable economic growth. But in the process of hydropower development, it causes migration and environment problems among hydropower developers, immigrants and ecological environment. To solve the interest conflict of all three parties, this paper first applies the replication dynamics analysis methods of evolutionary game theory to study the relationship among parties involved; secondly establishes a tripartite payment matrix and analytical dynamic equations to solve stability strategies of three parties in different conditions; finally, based on the stabilization strategy of game results, it proposes three suggestions for the sustainable hydropower development.

Abstract

The properties of supports have a significant effect on the activity of noble metal single atoms. In this work, Co-doped CeO 2 -supported single-atom Pt catalysts (Pt 1 /Co-CeO 2 ) have been acquired by a synchronous pyrolysis/deposition route and demonstrated to promote low-temperature oxidation of CO. Revealed by a model reaction of 1% CO + 1% O 2 + 98% He at a space velocity of 12,000 mL/g cat /h, CO conversion (100 °C) acquired on a (0.5% Pt)/(10% Co-CeO 2 ) catalyst (36.6%) was 3.6 and 4.9 times those of 0.5% Pt/CeO 2 (10.0%) and 10% Co-CeO 2 (7.4%) catalysts and 2.1 times that of their conversion sum (17.4%), confirming the positive role of the Co dopant in boosting the low-temperature oxidation of CO. The consistent results are also verified in the comparison of Pt 1 /Co-ZnO with Pt 1 /ZnO and Pt 1 /Co-Al 2 O 3 with Pt 1 /Al 2 O 3 . In addition, the activity of single-atom Pt 1 /Co-CeO 2 catalysts can be facilely modified by changing the loading of Pt and/or doping amount of Co. These reasonable data will provide a methodology to access more applicable catalysts for CO oxidation at low temperature.
