The synergistic effects of Pt-OH and Pt<sup>0</sup> enhanced the low-temperature catalytic performance of Pt/CNTs for preferential CO oxidation in a H<sub>2</sub> stream

Figure 1. (A) Temperature-dependent CO conversion profiles and (B) CO2 selectivity evolution in CO-PROX over CNTs, 0.3Pt/CNTs-CIW, and 0.3Pt/CNTs-IW catalysts. Reaction conditions: 1 vol% CO + 1 vol% O2 + 40 vol% H2, and Ar balance, WHSV: 18,000 mL·h-1·gcat-1. CIW: Collodial impregnation methaod; CO-PROX: preferential oxidation of CO in H2-rich stream; CNTs: carbon nanotubes; IW: incipient wetness impregnation.
