| Abstract: | • A novel monolithic catalyst composed of iron-mesh supported LDO was developed. • Vertically aligned Co-Fe LDO was immobilized on iron mesh by in-situ growth. • It showed better performance than cordierite supported honeycomb catalyst. • This catalyst showed significantly enhanced water vapor resistance. • CFD simulation indicates this catalyst possesses better heat distribution. A novel monolithic catalyst composed of iron mesh-supported vertically aligned Co-Fe layered double oxide (CoFe-LDO/IM) was successfully developed for the first time. The catalytic activity, water resistance, thermal stability, and computational fluid dynamics (CFD) simulation of CoFe-LDO/IM were comparatively studied with those of a conventional CoFe-LDO/cordierite catalyst. The optimal catalyst 30-CoFe-LDO/IM showed a 26 °C lower T 90 than CoFe-LDO/cordierite, significantly enhanced water vapor resistance (toluene conversion was 84% vs. 75%, 73% vs. 56% and 61% vs. 45% under 3, 5, 10 vol% H 2 O at T 90), and better thermal resistance within 5 cycles. CFD simulation demonstrated that the iron mesh-based monolithic catalyst possesses better heat distribution, which can prevent the partial deactivation of the catalyst and benefit the catalytic activity. We are fully convinced that this work can help pave the way for the design of next-generation monolithic catalysts with high activity and resistance for VOC oxidation. [ABSTRACT FROM AUTHOR] |
