Activation of peroxymonosulfate by single-atom Fe-g-C3N4 catalysts for high efficiency degradation of tetracycline via nonradical pathways: Role of high-valent iron-oxo species and Fe–Nx sites

Construction of a Z-scheme g-C3N4/NBGO/BiVO4 heterostructure with visible-light driven photocatalytic degradation of tetracycline: efficiency, reaction pathway and mechanism

“…1–7 Large amounts of wastewater containing antibiotics are directly discharged into water sources, which poses a massive threat to human health and causes serious environmental problems. 7–11 Thus, it is imperative to explore new control methods and water treatment technologies for removing TC from the water environment. In recent years, semiconductor photocatalysis degradation technology has gained widespread interest as a green and environmentally friendly way to degrade organic pollutants in water.…”

Cu-Doped magnetic loofah biochar for tetracycline degradation via peroxymonosulfate activation

“…5a and b, the contents of COOH and C-OH respectively decreased from 17.0% to 12.6% and 21.6% to 17.9% in WFe-LBC. This was because COOH and C-OH were involved in the reaction as active sites in the previous reaction (eqn (1) and ( 2)). 47 However, different phenomena appeared in the comparison between fresh Cu-Fe-LBC and used Cu-Fe-LBC (Fig.…”

“…In the past few decades, antibiotics have been considered as a hazardous contaminant. [1][2][3] Among antibiotics, tetracycline (TC) drugs have become one of the most widely used drugs for protecting animals and humans from infectious diseases due to their low cost, ease of synthesis and inhibitory effects on protein synthesis. And they are the second most consumed antibiotics in the world, resulting in a large number of environmental issues.…”

Supported Cu3 clusters on graphitic carbon nitride as an efficient catalyst for CO electroreduction to propene

“…[33][34][35] Among various 2D nanomaterials, graphitic carbon nitride (g-C 3 N 4 ) has been regarded as an excellent substrate for supporting metal-based catalysts, because it contains intrinsic evenly distributed holes surrounded by electron-rich N atoms, which can provide abundant electron lone pairs for anchoring metal ions within its ligands. [36][37][38][39][40][41][42] In particular, g-C 3 N 4 could act as a molecular scaffold for appropriately tuning the electronic properties of the anchored metal centers to endow them with high catalytic activity and selectivity in electrocatalysis. [43][44][45] Motivated by the aforementioned studies, taking the widely investigated Cu as a module, we investigated the catalytic performance of several sub-nano Cu n (n ¼ 1-6) clusters supported by g-C 3 N 4 (Cu n @g-C 3 N 4 ) as COER catalysts by means of density functional theory (DFT) computations.…”
