“…2) for environmental remediation, catalysis, sensing, and energy conversion and storage applications due to its ease to prepare, unique 2D structure, and tunable O groups. 6,60,[68][69][70][71][72][73] Environmental Science: Nano Critical review Differentiation of specific O groups in the PMS/PDS activation is challenging due to the simultaneous variation of all kinds of O groups with regulation conditions. Some methods have been reported to finely mediate the surface O groups on the carbocatalyst surface.…”

“…The increasing environmental pollution with the fast development of various industries calls for efficient and lowcost methods to remove the toxic and refractory pollutants from water radically. [1][2][3][4] The current methods involve adsorption, [5][6][7] Fenton oxidation, 8,9 Fenton-like oxidation, 10,11 electro-Fenton, 12,13 photo-Fenton, 14,15 electrochemical oxidation, 16,17 photocatalysis [18][19][20][21] and others. [22][23][24][25][26] Among these methods, Fenton-like oxidation based on peroxomonosulfate (PMS) and peroxydisulfate (PDS) has attracted significant attention due to its long life spans, strong oxidation ability, ease of storing and transporting PMS/PDS relative to liquid H 2 O 2 , applicability to a diversity of refractory organic pollutants, and capability to withstand a wide pH range, which is superior to the Fenton process requiring H 2 O 2 as the reactant, thus causing the storage and delivery to be difficult.…”

Poly(hexamethylene biguanide) hydrochloride (PHMB)-based materials: synthesis, modification, properties, determination, and application

“…Numerous techniques such as adsorption, oxidation, membrane separation and flocculation have been developed nowadays for water treatment. [186][187][188] PHMB is typically used as a disinfectant/biocide to kill the microorganisms in water. 189,190 Ma and colleagues developed a dual-functional magnetic porous microsphere chemically modified with PHMB for highly efficient and recyclable water disinfection and dye removal.…”

Effect of Carbon Layer Thickness on the Electrocatalytic Oxidation of Glucose in a Ni/BDD Composite Electrode

“…Boron-doped diamond (BDD) is highly promising as an electrode material with a high oxygen evolution potential, high corrosion resistance, and good anti-pollution properties [21]. In the form of solid films for carrying sensitive nanostructures (e.g., Au, Pt, Ag, Cu, or Ni), BDD is structurally stable and can be prepared by a simpler preparation process with better reproducibility compared with other carbon materials such as carbon nanotubes and graphene [22,23]. More importantly, BDD can be directly grown onto substrate electrodes, without involving secondary loading.…”
