The pore size range of activated carbon has an important effect on formaldehyde adsorption, while nitrogen-doped can promote but the mechanism adsorption at different not been elaborated clearly. Therefore, this paper investigates scales. Through simulation, it is concluded that does broaden optimal for and still 6 Å, improve non-bonding interactions between molecules by changing electrostatic distribution surface carbon, which enhances molecules. In addition, interaction decreases with...
Silver and silver oxide nanoparticles were impregnated on the surface of powdered activated carbon (PAC) using a single-step liquid phase plasma (LPP) method. Spherical 20 to 100 nm size dipersed evenly PAC. The PAC exhibited higher activity for decomposition bromate than bare XPS, Raman EDX analyses showed that Ag/PAC composites synthesized by LPP process.
The adsorption of carbon materials and 2e-ORR performance can be promoted by N-doping. However, the effect different N-doping types on their synergy is not clear, which limits development an electro-Fenton system. We used multi-scale simulation method to elucidate mechanism promote cathode performing molecular dynamics quantum chemical simulation. also investigated between experiments. results showed a synergistic performance. Improving only one properties resulted in poor degradation...
Surface oxygen modification of activated carbons has been considered as effective sorbents to remove formaldehyde from indoor air while the role co-existed moisture on adsorption by oxygen-rich is not clear. In this study, a series with controlled content were synthesized and impact water simulated studied experimentally theoretically. Formaldehyde ratio increased increasing functional groups carbon surface. However, gradually decreased relative humidity increased. The improvement originated...
The synergistic effect of intrinsic defects and oxygen-containing functional groups on formaldehyde adsorption the surface carbon materials was simulated verified by experiments. Based density theory, characteristics different were quantum chemistry. mechanism studied energy decomposition analysis, independent gradient model based Hirshfeld partition (IGMH), theory atoms in molecules (QTAIM), charge transfer, binding hydrogen bond estimated. results showed that compared to configuration...
In the electro-Fenton system with activated carbon as cathode, different nitrogen-doped types have effects on decomposition of H2O2 to generate ·OH and promotion adsorption degradation formaldehyde. Regulating achieve synergy generation utilization is key formaldehyde degradation. this paper, capacity for H2O2, ability activation ·OH, mechanism by were explored. A reasonable method that realizes efficient between has been obtained. The results show pyridinic nitrogen promoted cathode...
Exploring the dynamic mechanism of pore structure and surface functional groups on formaldehyde adsorption is key to understanding root cause low capacity activated carbon formaldehyde. In this paper, volume change subsequent micropores with different sizes under processes were deeply investigated by a combination multi-scale simulation methods. The interaction between molecules in pores was dissected. influence law carboxyl explored. results indicate that narrow effective size range one...
