Catalytic oxidation of NO by activated carbon fiber (ACF)

Surface structure and adsorption properties of ultrafine porous carbon fibers

“…It should be also noted that the role of UPCF or CPCF1 is not only an adsorbent, but also a catalyst, since the steady-state level of NO remains below that at the inlet. The oxidation of NO into NO 2 forms intermediates, such NO 3 and NO-NO 3 , and finally NO 2 is desorbed [28]. S BET : BET surface area; V t : total pore volume; V m : micropore volume; PSD: pore size distribution.…”

NH3-activated carbon nanofibers for low-concentration NO removal at room temperature

“…The breakthrough characteristics of NO x over NCNFs can be explained using the Langmuir-Hinshelwood mechanism [1], a preferred heterogeneous catalysis model. In the model, NO and O 2 are firstly adsorbed on the vacant active sites of NCNFs, then NO was oxidized into the adsorbed NO 2 (C-NO 2 ).…”

“…Hence, a highly efficient catalyst that can catalytically oxidize NO into NO 2 at room temperature is in great need. Carbon materials are the promising catalysts for the oxidation of NO into NO 2 [12,13], because activated carbon materials contain a large number of micropores and high surface area and NO dimerization can be enhanced by micropores [14], and activated carbon materials are superior adsorbent for NO at low temperature [15] and widely used as catalysts in the oxidation of NO [1,5,16,17].…”

“…Nitrogen oxides (NO x , mainly as NO and NO 2 ) emitted from anthropogenic activities are considered as primary atmospheric pollutants, because NO x can deteriorate the environmental and human health [1,2]. Numerous environmental issues, e.g.…”

NO Catalytic Oxidation Behaviors over CoOx/TiO2 Catalysts Synthesized by Sol–Gel Method

“…The catalysts commonly used for the oxidation of NO include several kinds of activated carbons [11,12], noble metal [13,14], metal oxides and metal doped catalysts [15,16]. Among these catalysts, metal oxides catalysts, especially for cobalt oxides, are received special attention because of their unique properties, such as high oxidation efficiency, inexpensiveness and persistent activity.…”
