The role of activated carbon as a catalyst in GAC/iron oxide/H2O2 oxidation process

Prussian Blue onto Activated Carbon as a Catalyst for Heterogeneous Fenton-Like Processes

“…The consumption rate of H 2 O 2 slightly decreases in the presence of Orange G, probably due to a partial blockage of active sites by the adsorbed dye, and by the competition of the organic species for the generated radicals' propagation. This is in line with outcomes reported with GAC for 4-chlorophenol and phenol by [2] and [12], respectively.…”

Efficient Absorption of Antibiotic from Aqueous Solutions over MnO2@SA/Mn Beads and Their In Situ Regeneration by Heterogeneous Fenton-Like Reaction

“…The significant mechanisms include that NOR and H 2 O 2 molecules occupied the bare active sites on the surface of the alginate; then NOR was removed by the oxidizing radicals created by the decomposition of H 2 O 2 and dissolved into the solution, similar results were acquired by Tunç et al [62]. Although NOR in solution could be removed by the pure alginate beads in the UV/H 2 O 2 system, the adsorbed NOR could block the activated sites and decrease catalytic efficiency on the surface of the alginate towards the H 2 O 2 decomposition [63]. However, compared with the pure alginate beads, the MnO 2 @SA/Mn has achieved a higher removal rate in the UVFenton-like system.…”

Removal of ampicillin sodium in solution using activated carbon adsorption integrated with H2O2 oxidation

“…Granular activated carbon (GAC) has also been used for some time now in heterogeneous catalysis, because it can be used as a direct catalyst or as a catalyst support for specific needs. 12 Previous studies have reported that H 2 O 2 in the presence of activated carbon could oxidize organics such as 4-chlorophenol and dyes. 13,14 Some authors have proposed that activated carbons with basic characteristics show a higher capacity to decompose hydrogen peroxide.…”
