Petal-like hierarchical Co3O4/N-doped porous carbon derived from Co-MOF for enhanced peroxymonosulfate activation to remove tetracycline hydrochloride

Enhanced catalytic performance of Co3O4/Eu2O3 with sulfur-modification in activating peroxymonosulfate for removal of methylene blue

“…51 Meanwhile, a part of ˙SO 4 − formed in the system would react with H 2 O or OH − to produce ˙OH, which could further react with HSO 5 − to generate ˙O 2 − (eqn (14)–(16)). 52 In addition, ˙O 2 − could also be formed by the reaction of oxygen dissolved in the solution with the electron provided from the catalyst surface (eqn (17)). As for the formation of 1 O 2 , it might result from the reaction of ˙OH and ˙O 2 − (eqn (18)).…”

Fast Degradation of Rhodamine B by In Situ H2O2 Fenton System with Co and N Co-Doped Carbon Nanotubes

“…In addition, carbon-based catalysts have attracted more attention due to their environmental sustainability, ease of manufacturing, low cost and abundance [ 11 , 12 ]. Moreover, the surface chemistry and pore structure of carbon-based catalysts can be easily adjusted to obtain more accessible active sites and faster mass transfer according to the preparation conditions [ 13 , 14 ]. The doping of metal, nitrogen and oxygen functional groups has been proved to be an effective strategy to improve their catalytic activity and H 2 O 2 selectivity, which will significantly affect the oxidation performance.…”

The Potential of Spent Coffee Grounds @ MOFs Composite Catalyst in Efficient Activation of PMS to Remove the Tetracycline Hydrochloride from an Aqueous Solution

“…Due to its high persistence, biological activity, antibiotic resistance, and toxic effects on ecosystems [ 12 ], TC may lead to contamination of the environment, water resources, and soil. Many treatment methods to remove TC from an aqueous solution were investigated, e.g., adsorption [ 13 ], photocatalysis [ 14 ], electrocatalysis [ 15 ], and the Fenton oxidation processes [ 16 ]. Among those TC removal routes, the advanced oxidation processes (AOPs) based on persulfate (PS) have attracted increasing attention in recent years [ 17 , 18 ]; this is because the sulfate radical (·SO 4 − )-based AOPs have superior oxidation potential (E 0 = 2.5–3.1 V), a wider pH operating range, and a longer half-life time (30–40 μs) [ 19 ].…”
