Co3O4@Fe3O4/cellulose blend membranes for efficient degradation of perfluorooctanoic acid in the visible light-driven photo-Fenton system

A self-synthesised non-homogeneous MoS2/Fe–Co–N–BC composite catalyst as an activator for peroxomonosulfate activation for efficient degradation of perfluorooctanoic acid

“…The multivalent states of Co indicate the surface oxidation of Co NPs in air. 4,12 As shown in Fig. 2d, Fe 2p of biochar can be decomposed into Fe 0 , Fe 2+ and Fe 3+ .…”

“…It is listed in the list of 2B carcinogens by the World Health Organisation. [4][5][6] Therefore, the study of the effective removal of PFOA by advanced oxidation processes is of practical significance.…”

Enhanced Performance of Porphyrin-Modified CuO-Co3O4 Heterojunction as a Photoelectrocatalyst for Methanol Oxidation

“…First, TCPP/Cu 2 Co 1 adsorbs methanol molecules around it in 1 M CH 3 OH + 1 M KOH electrolyte. Second, the photogenerated electrons are accumulated at Co 3 O 4 , and the photogenerated holes are transferred to the HOMO of the TCPP. − This process effectively inhibits the recombination of photogenerated electrons and holes, thus allowing the efficient separation and transfer of photogenerated charges in the TCPP/Cu 2 Co 1 catalyst. Finally, the methanol molecules adsorbed on the catalyst surface are oxidized by the photogenerated holes.…”

Covalent Organic Framework/Graphene Hybrids: Synthesis, Properties, and Applications

“…[4,5] Effortlessly straddling multiple applications, [6] COFs have unfurled their enormous potential in realms such as water purification, [7] photocatalysis, [8][9][10] environmental sensing, [11] energy storage, [12][13][14] and gas storage/separation. [15][16][17][18] Nevertheless, an objective appraisal reveals that certain inadequacies persist within solid-state COFs, which include inferior electric conductivity, [19,20] inaccessible active sites, [21] impeded mass transfer, and poor processability. These shortcomings have curtailed their application across novel sectors such as electrochemistry, [22] catalysis, [23] and membrane separation.…”
