“…TPAOH and CTAB were used as desilicillants and structure guide agents to synthesize a ZSM-5 molecular sieve, and it was found that improved anti-SO 2 performance could be attributed to hierarchical pore structure. 33 The catalysts (FeM 0.3 O x -C, M = Nb, Ti, Mo) showed better SCR performance with the addition of CTAB, and the crystalline phase of Fe 2 O 3 was effected by adding CTAB. 34 CTAB was used for the self-assembly of Fe-ZSM-5@ Ce/mesoporous-silica, which showed higher NO x conversion, and the mesoporous silica shell promoted the dispersion of Ceria with a higher redox ability of catalysts.…”
