Supported cobalt oxide on graphene oxide: Highly efficient catalysts for the removal of Orange II from water

Graphene supported heterogeneous catalysts: An overview

“…Cu 2 O is an environmentally friendly semiconductor which has attracted intense attention as a promising candidate for electrochemical sensors, owing to its low cost and excellent catalytic activity [372,373]. Unsupported Cu 2 O heterogeneous catalysts are recorded to be very active oxidation catalysts, but are thermally unstable at evaluating temperatures [372].…”

Direct fabrication of lamellar self-supporting Co3O4/N/C peroxymonosulfate activation catalysts for effective aniline degradation

“…In previous works, scientists designed carbon-supported iron-and cobalt-nitrogen materials constituting active catalysts for the degradation of organic compounds [26][27][28]. And, recent research showed that adding a semiconductor onto a suitable support and coupling two or more semiconductors can decrease the recombination of electron-hole (e-h) pairs, which can increase the activity of the semiconductor [29][30][31][32][33][34].…”

Activation of peroxymonosulfate with magnetic Fe3O4–MnO2 core–shell nanocomposites for 4-chlorophenol degradation

“…However, degradation of refractory organic pollutants can be hardly achieved using conventional wastewater treatment technology due to the stable structure of organic compounds. Advanced oxidation is a promising pathway to mineralize the refractory organic pollutants through the activation of the oxidants and thus generating highly oxidizing radical species [2,3]. attentions due to its high redox potential (2.5-3.1 V) at neutral pH [4] and more selective for oxidation [5].…”
