Recently, to solve the problem of NOx pollution effectively, the development of catalysts for NH3-SCR at low temperature and good resistance to SO2 and H2O is still a challenge. Researches show that MOFs derivatives obtained by pyrolysis of MOFs could retain the advantages of MOFs, which provides a possibility for MOFs derivatives to be applied in thermal catalysis. Especially, in-situ generation of residual C element in MOFs derivatives received by control of suitable calcination temperature has the potential to stimulate catalytic activity. Therefore, in this work MOFs derivative carrier containing residual C was prepared and Titanium silicalite molecular sieves (TS-1) was selected for comparison (Carbon-free). The experimental results reveal that MnCe@MOF-C has a better low-temperature NH3-SCR performance and considerable H2O and SO2 resistance. Further investigations show that the residual C enhanced the electron transfer in the catalyst, thus reconstructed the valence allocation of the surface ions and created more surface oxygen vacancies to accelerate redox reaction. This study illustrates the effect of residual C in an electron-level, which provides a theoretical guidance to the application of MOFs derivative carrier in NH3-SCR.
