室温CO催化氧化反应动力学的研究

Reaction Kinetics on CO Oxidation over Different Catalysts at Ambient Temperature

本文采用无梯度反应器,考察了纳米金催化剂以及其它商品化的催化CO氧化催化剂,在不同CO浓度下催化CO氧化反应的转化率和反应速率,证明在CO初始浓度从ppm到pct数量级范围内,纳米金催化剂具有最好的催化CO室温转化的能力.

CO oxidation over Au catalysts and other commercial catalysts has been investigated using batch reactor. The activity denoted as CO conversion and the initial reaction rate constant has been calculated, and the result shows that the nano-gold catalysts exert the best performance within the range of the CO concentration of the order from ppm to pct companng with the other catalysts.
