“…In the present research, in comparison with AC, CNTs exhibit superior mass transition efficiency, thermal stability, and better dispersion of nanoparticles. 58,59 In addition, the mesoporous structure of the support plays an important role in the improvement of catalytic performance by allowing the penetration of macromolecules and their adsorption on the surface of the catalyst. Acid treatment with HNO 3 and H 2 SO 4 is the most common technique for surface modification; this method introduces functional oxygencontaining groups, 60 resulting in breaks in nanotubes and removal of amorphous carbon.…”

The catalytic activity of a series of Cu–Ce catalysts supported on carbon nanotubes was studied for NO reduction by CO. The 20 wt % Cu1:Ce3/CNT catalyst showed the highest NO x conversion of 96% at 220 °C in the presence of oxygen (O2/CO ≤ 0.6). The catalytic activity of the CNT-supported catalysts was significantly enhanced due to synergistic interactions between surface oxygen vacancies and Cu+ species in the CNT-supported catalysts. Shifting of redox equilibrium to right (Cu2+ + Ce3+ ↔ Cu+ + Ce4+) resulted in creation of more reduced state Cu+. In the presence of excess oxygen (O2/CO ≥ 0.6), the catalyst can effectively catalyze the CO–O2 reaction and the NO + CO reaction did not occur. Compared with Cu1:Ce3/CNT catalyst, Cu1:Ce3 catalyst supported on activated carbon showed lower activity due to the lower Cu+/Cu2+. A possible reaction mechanism was proposed, providing insight into the catalytic reactions between NO and CO.
