Experimental investigation into the pore structure and oxidation activity of biodiesel soot

Diesel particulate filter regeneration mechanism of modern automobile engines and methods of reducing PM emissions: a review

“…So that the oxygen could penetrate and react with the internal surface area. The same conclusion appeared in the report of Du et al (Du et al 2022 ). They believed that the greater the porosity and specific surface area, the stronger the oxidation reactivity of soot.…”

“…Oxygenated fuel promoted the disorder of soot and the increased of the number of carbon atoms at the edge (Serhan et al 2018 ) di-propylene glycol methyl ether better Diesel engine,2.83L 4-cylinder soybean oil methyl eater better On the one hand, the high oxygen content of biodiesel inhibited the production of polycyclic aromatic hydrocarbons in soot. On the other hand, the high oxygen content contributes to the high porosity of soot, which reduced the activation energy required for soot oxidation (Du et al 2022 ) palm oil methyl ester better waste cooking oil methyl ester better ASTM D1322 burner acetone-butanol-ethanol better The derived soot of ABE blended fuel contained more aliphatic compounds. These aliphatic chains at the edge of soot could attach more oxygen-containing functional groups to enhance the oxygen content of soot.…”

Unveiling the Surface Chemical Reactions during Multi-Phase Catalytic Oxidation of Soot on Nanoengineering/Interfacing/Doping-Prepared Mn-CeO2 Catalysts Using TG-MS and Operando DRIFTS-MS

“…H3 hysteresis mainly exists in medium or large porous materials with flat cracks. The multilayer adsorption of medium or macro porous media is thought to include the N 2 adsorption of soot and catalyst combination . The values of specific surface area ( S BET ), pore volume ( V pore ), and mean pore size ( d pore ) are filled in Table .…”

A One‐Step Self‐Flowering Method toward Programmable Ultrathin Porous Carbon‐Based Materials for Microwave Absorption and Hydrogen Evolution

“…The defects of carbon nanosheets were mainly caused by the doping of N (including pyridinic, pyrrolic, and graphitic N) and O (CO and CO) from the analysis of X‐ray photoelectron spectroscopy (XPS, Figure S5, Supporting Information). The N 2 adsorption–desorption isotherms with the comprehensive characteristic of type II/IV confirmed the coexistence of both micropores and mesopores in NPC [ 9 ] (Figure 1f; Figure S6a,b, Supporting Information). Especially, the pore size distribution curve calculated by density functional theory (DFT) analysis showed a sharp peak at 1.27 nm, corresponding to a large number of micropores on the ultrathin nanosheets.…”
