以Al(OH)3为载体制备了η-Al_2O_3上的铂单原子催化剂。碱性表面的MgO/Pt/Al_2O_3有利于CO在H_2O条件下的氧化；H_2O对催化剂上碳酸盐的吸附有抑制作用；W_2O_3/Pt/Al_2O_3表面酸性的WO_3/Pt/Al_2O_3对甲醇的分解具有很高的活性。催化剂表面的氧空位是甲醇吸附的活性中心。
HighlightsPt single atom catalyst on η-Al 2 O 3 was fabricated based on an Al (OH) 3 support.MgO/Pt/Al 2 O 3 with basic surface was beneficial for CO oxidation under H 2 O condition.H 2 O inhibited the adsorption of carbonates on catalysts in CO oxidation.WO 3/Pt/Al 2 O 3 with acidic surface was highly active for methanol decomposition.Oxygen vacancies on catalyst surface were the active sites for methanol adsorption.
