Effects of amorphous-zinc-silicate-catalyzed ozonation on the degradation of p-chloronitrobenzene in drinking water

Two‐Dimensional Layered Zinc Silicate Nanosheets with Excellent Photocatalytic Performance for Organic Pollutant Degradation and CO2 Conversion

“…TheO 1s peak can be deconvoluted into three peaks:t wo main peaks at 532.5 and 531.8 eV,and asmall shoulder located at about 532.3 eV.The former two peaks may be assigned to the Si À O À Si bonds and the OÀZn bonds,respectively,and the latter results from the -OÀHb onds on LZS. [17] TheZ n 2p 3=2 signal of LZS shows asymmetric peak centered at 1022.4 eV,which is the same as that the reported earlier for zinc silicate (hemimorphite). [18] TheSi 2p binding energy in LZS is 103.1 eV,close to the value observed for as ilicate.…”

Role of Fe/pumice composition and structure in promoting ozonation reactions

“…The considerably low reactivity of p-CNB towards biodegradation makes it harmful to aquatic environments. In addition, p-CNB is difficult to remove using chemical oxidation and has low adsorption onto solid surfaces [20,[27][28][29]. Therefore, p-CNB was a well suited model pollutant for catalytic ozonation testing.…”

Rapid removal of p-chloronitrobenzene from aqueous solution by a combination of ozone with zero-valent zinc

“…It has been confirmed that activated carbon [7], metal oxides [8][9][10] or metal oxides loaded on the some materials [11], and zinc silicate [12] possess the promising capacity for catalytic ozonation. Besides, zero-valent iron (Fe(0)) is also able to be used as a catalyst to enhance the degradation of organic contaminants by ozone [13,14].…”
