Catalytic wet peroxide oxidation of phenol from industrial wastewater on activated carbon

CuO impregnated activated carbon for catalytic wet peroxide oxidation of phenol

“…In this study, a higher copper loading and oxidation activity can be obtained by the raw coconut shell immersion with Cu(NO 3 ) 2 . As was noticed in previous works, a commercial activated carbon was selected in a reaction condition of high temperature (160 • C) and oxygen pressure (16 bar) [35] and activated carbon-supported copper catalyst prepared from sulfonated styrene-divinylbenzene resin [36] showed deactivation since large copper leaching for high concentration (1000 mg L −1 ) of phenol oxidation. The CuAC catalyst shows high oxidation performance to treat phenol with low energetic cost and in a mild reaction condition.…”

Heterogeneous catalytic degradation of phenolic substrates: Catalysts activity

“…Very recently, an industrial stream-containing phenol, collected in a naphtha cracking unit of a petrochemical plant, was used to test the performance of a heterogeneous catalyst obtained from copper adsorption by an ionic-exchange resin (sulfonated styrenedivinylbenzene), followed by carbonization [115]. The catalyst was characterized before and after the catalytic tests by SEM-EDS.…”

Heterogeneous Fenton Catalysts Based on Activated Carbon and Related Materials

“…As we com- mented earlier, metal leaching is a common problem in ACsupported metal catalysts. In this sense, the leaching of a substantial percentage of copper in a related polymer-supported copper catalyst has been determined, [50] and it is very likely that this phenomenon also occurs in this series of CuAC solids. Thus, it would be of interest to perform analytical tests on copper leaching and how this leached species contributes to the observed catalytic activity and affects the stability and reusability of the CuAC solids.…”
