摘要

CO是一种分布广泛的空气污染物，对环境和人体健康构成重大威胁。目前，CO热催化氧化被认为是最节能、最高效的转化方法，而采用传统浸渍法制备的Pt/CeO

催化剂已接近其催化性能的极限。对于负载型Pt/CeO

单原子催化剂而言，载体的表面性质以及金属单原子的局部配位环境对其催化性能有重要影响。通过浸渍法引入磷酸制备了P改性单原子催化剂Pt/CeO

，利用XRD、CO-DRIFTS和FT-IR等方法对催化剂的结构进行了表征，并对其催化性能进行了研究。结果表明，当

(磷酸)/

(CeO

) ≤ 0.0850时，Pt以单原子的形式存在于催化剂中。Pt/CeO

中，形成了P—O—Pt 配位，并且其Lewis酸量增大，也产生了微量的Brønsted酸，有利于CO吸附。同时，Pt/CeO

的还原性能提高，所以其CO低温氧化催化性能明显提升。其中，Pt/CeO

-0.085PO

催化性能最优，使得CO转化温度降低为40 ℃，CO转化率达到100%的温度降低为110 ℃。

Abstract

CO is a widely distributed air pollutant that poses a significant threat to the environment and human health. At present

CO thermal catalytic oxidation is considered to be the most energy-efficient and efficient conversion method

but the Pt/CeO

catalyst prepared by traditional impregnation method is close to the limit of its catalytic performance. For supported Pt/CeO

single-atom catalyst

the surface properties of the support and the local coordination environments of the metal single-atom play an important role in its catalytic performance. The P-modified single-atom catalyst Pt/CeO

was prepared by the introduction of phosphoric acid by impregnation

and the structure of the Pt/CeO

was characterized by XRD

CO-DRIFTS

FT-IR and so on

and the catalytic performance was studied. The results show that when

(phosphoric acid)/

(CeO

) ≤ 0.0850

Pt exists in the catalyst as a single atom. For Pt/CeO

P—O—Pt coordination is formed

and its total amount of Lewis acid sites increases

and a trace amount of Brønsted acid is also generated

which is beneficial for

the CO adsorption. At the same time

the reduction performance of the catalyst is improved

so the catalytic performance for low-temperature CO oxidation is significantly improved. Pt/CeO

-0.085PO

shows the best catalytic performance

reducing the CO conversion temperature to 40 ℃ and reducing the temperature at which the CO conversion rate reaches 100% to 110 ℃.
