Preparation and characterization of a new waste-derived mesoporous carbon structure for ultrahigh adsorption of benzene and toluene at ambient conditions

Hierarchically porous N‐doped carbon nanofibers derived from ZIF‐8/PAN composites for benzene adsorption

“…VOCs, such as, acetone, benzene, toluene, and ethylbenzene produced by the petrochemical or related industries are harmful to our living environment and human health due to its features of toxic, hazardous, and carcinogenic 1 . Of these VOCs, benzene has attracted particular attention because of its common utilization as raw material and solvent in chemical industries, resulting in a facile benzene liberating from variety of sources, such as artificial leathers, synthetic rubbers as well as printers 2,3 . It has been reported that the exposure of over 8 h time‐weight average basis for benzene can induce a negative impact on health, and even make a risk of cancer for the human being 4 .…”

Defect-rich N doped porous carbon derived from Camellia shells for chlorobenzene adsorption

“…The larger rate constants K T for the Thomas model and K YN for the Y–N model indicate that the mass transfer resistance in the adsorption process is smaller. 46,50–52 According to Table 5, both K T and K YN of ANOC-1.5 were higher than that of AOC, which indicated that NAOC-1.5 had less mass transfer resistance during the dynamic adsorption process. This was related to the presence of more mesopores in ANOC-1.5, which provided richer mass transfer channels for chlorobenzene.…”

Preparation of high-performance toluene adsorbents by sugarcane bagasse carbonization combined with surface modification

“…Tehrani et al reported there was an interaction between the p electron density of AC and N-containing functional groups; moreover, Ncontaining functional groups had an affinity for toluene, which was favorable for toluene adsorption. 34 According to the fraction of N-containing functional groups and the binding energy of toluene on N-containing functional groups, 13 pyridinic-N (N-6) contributed more to toluene adsorption for AC-800. Moreover, XPS spectra proved that there were O]C-OH, C-O, C]O, C-OH, O-C]O, and C-O-C oxygen containing functionalities on the AC-800 surface (Fig.…”
