Insights into Fenton-like oxidation of oxytetracycline mediated by Fe-doped porous g-C₃N₄ nanomaterials: synthesis, performance and mechanism

Abstract

Fe/PCN nanomaterial synthesized via a one-step self-assembly strategy was proposed to provide guidance for the removal of OTC.

Combined effect of Cu0 and oxygen vacancies in Cu-based zeolites enables highly efficient photo-Fenton-like performance for water purification

“…The toxicity of the DCF degradation intermediates was evaluated by the toxicity estimation software tool (T.E.S.T), including the fathead minnow LC 50 -96 h, Daphnia magna LC 50 -48 h, oral rat LD 50 , and bioaccumulation factor. 58 Fig. 8b shows the reduced fathead minnow LC 50 -96 h value of all degradation intermediates except product B, and products G and K even became no longer harmful after further decomposition.…”

Inverse opal manganese-doped tungsten trioxide as a high-performance Fenton-like photocatalyst for levofloxacin degradation

“…IO Mn–WO 3 had the widest band gap and the most negative conduction band position. It was easier for the photogenerated electrons to react with dissolved oxygen to form ˙O 2 − due to the more negative value of the conduction band position of IO Mn–WO 3 (−0.66 eV) compared to the value of E 0 (O 2 /˙O 2 = −0.33 eV vs. NHE 68 ), implying that it was favourable to produce more reactive oxygen species to improve the photo-Fenton-like reactivity.…”

In situ single iron atom doping on Bi2WO6 monolayers triggers efficient photo-fenton reaction

“…The photo-Fenton process has been regarded as a green and sustainable catalytic process. It can introduce photogenerated electrons to accelerate the Fe( )/Fe( ) circulation ( ), which effectively promote the rate-limiting step of Fenton reaction [ [14] , [15] , [16] , [17] ]. Therefore, the key to constructing a high-efficiency photo-Fenton system is developing highly efficient semiconductor materials with abundant active sites and excellent electron transfer ability for H 2 O 2 activation [ [18] , [19] , [20] , [21] , [22] ].…”
