Drastically enhanced tetracycline degradation performance of a porous 2D g-C3N4 nanosheet photocatalyst in real water matrix: Influencing factors and mechanism insight

Tailored Citric Acid-Functionalized Carbon Nitride Homojunction-Immobilized Carboxymethyl Cellulose 3D Photocatalytic Hydrogels: A Multifaceted Approach toward Environmental Remediation

“…The XRD spectra of the prepared photocatalysts are displayed in Figure b. The prepared photocatalysts exhibited two prominent peaks around 13 and 27°, corresponding to the (100) and (002) crystal plane of the carbon nitride (JCPDS 87-1526), respecitvely . The (100) plane is attributed to the in-plane structural packing motif of the tri- s -triazine unit of the graphitic carbon nitride framework, and the (002) plane ensures the interplanar stacking of the aromatic unit of the GCN framework. , …”

“…The drinking water and tap water exhibited negligible effects on the photocatalytic degradation of tetracycline. However, the removal efficiency is substantially decreased for the lake water due to the higher concentration of natural organic matter obstructing the light absorption . The inner filtration of natural organic matter reduces active sites’ availability and the production of reactive oxygen species …”

“…However, the removal efficiency is substantially decreased for the lake water due to the higher concentration of natural organic matter obstructing the light absorption. 37 The inner filtration of natural organic matter reduces active sites' availability and the production of reactive oxygen species. 54 The practicability of the ICN/CMC hydrogels toward treating industrial wastewater was assessed.…”

Food-waste-derived hydrochar to a low-cost p-type semiconducting photocatalyst (Zn–Al@HC): multifunctional role in real wastewater treatment and environmental sustainability

“…The PL spectroscopy was conducted in the wavelength range of 200 nm to 600 nm with an excitation wavelength of 350 nm at ambient temperature. A similar protocol for the PL characterization was followed by Li et al and Ghosh et al 17,18 Additional electrochemical analysis including Cyclic Voltammetry (CV), Linear Sweep Voltammetry (LSV), Mott-Schottky (M-S) analysis, and Electrochemical Impedance Spectroscopy (EIS) were conducted both under UV irradiation and in the dark to determine the photocurrent response.…”
