“…This internal heating of the catalyst not only provides a method to achieve flexible, compact and efficient thermal control of the catalytic reaction, but also greatly improves the activity and resistance to humidity of the catalyst through electronic effects. As the current intensity increases, the conducting channel in the structural catalyst changes significantly and some electrons choose to do it in the catalytic layer rather than the skeleton, making EIH different from ESH on a microscopic scale [26] . The increased activity of EIH be attributed to three co‐existing factors.…”

“…As the current intensity increases, the conducting channel in the structural catalyst changes significantly and some electrons choose to do it in the catalytic layer rather than the skeleton, making EIH different from ESH on a microscopic scale. [26] The increased activity of EIH be attributed to three co-existing factors. First, EIH provide more uniform temperature distribution in the catalytic layer, because close contact with the electric heat source reduce the temperature gradient within the catalyst layer and improve the utilization rate of the catalyst, because it is difficult to form a significant temperature gradient under the ESH condition.…”

Structured catalysts are widely used in catalytic oxidation of gaseous pollutants, hot catalysis is usually needed to assist the reaction in the catalytic process. In this paper, a Ce modified manganese oxide octahedral molecular sieves (Ce‐OMS‐2) structured catalyst supported on foam nickel was prepared through impregnation process. And a systematically quantitative testing on the toluene catalytic oxidation effectiveness of this structured catalyst was conducted through catalyst evaluation device, combining a series of characterization methods such as XRD, SEM, the structure‐activity relationship was established. Assisted with electric internal heating and ozone oxidation environments, this structured catalyst exhibits excellent catalytic oxidation performance for oxidative decomposition of toluene even under high humidity conditions. The results showed that the ozone‐coupled structured nickel foam catalyst increased the decomposition efficiency of toluene from 25% (Without catalyst and heating) to 55% (With catalyst and without heating) and the internal heating can significantly improve the reactivity and moisture resistance of the structured nickel foam catalyst, at 90%RH and 40000h‐1, 50000 ppb O3 and 40mg/m3 toluene was maintained 100% catalytic efficiency. The high efficiency non‐precious metal based electrothermal catalyst prepared in this paper is expected to have certain enlightenment for the purification of VOCs.
