Highly crystalline carbon nitride (CCN), benefiting from the reduced structural imperfections, enables improved electron-hole separation. Yet, phase with insufficient inherent defects suffers a poor performance toward reaction intermediate adsorption respect to amorphous phase. Herein, crystalline-amorphous (CACN) an isotype structure was constructed via two-step adjacent calcination strategy. Through specific oxygen etching and crystallization, formation of built-in electric field at interface could drive charge transfer separation, thus promoting photoredox reaction. As expected, optimized CACN exhibited H

In recent years, organic pollutants have become a global problem due to their negative impact on human health and the environment. Photocatalysis is one of most promising methods for removal from wastewater, oxide semiconductor materials proven be among best in this regard. This paper presents evolution development metal nanostructures (MONs) as photocatalysts ciprofloxacin degradation. It begins with an overview role these photocatalysis; then, it discusses obtaining them. Then, detailed review important semiconductors (ZnO, TiO2, CuO, etc.) alternatives improving photocatalytic performance provided. Finally, study degradation presence main factors affecting carried out. well known that antibiotics (in case, ciprofloxacin) are toxic non-biodegradable, which can pose threat environment health. Antibiotic residues several impacts, including antibiotic resistance disruption photosynthetic processes.

This study explores the enhancement photocatalytic properties cerium dioxide (CeO2) nanorods by doping with lanthanum (La) improve efficacy in degrading aqueous solutions Congo red dye. CeO2 were synthesized via a hydrothermal method subsequently doped varying concentrations La. scanning electron microscopy (SEM) images confirmed rod-like structures (nanorods) observed for all samples, while energy-dispersive X-ray spectroscopy (EDX) homogeneous incorporation La matrix. diffraction (XRD) spectra demonstrate lattice distortion substitutional defect. Photocatalytic experiments revealed that La-doped exhibited significantly enhanced degradation capabilities compared undoped counterparts, achieving up 3-fold kinetics ((30 ± 2) × 10−3 min−1) counterparts ((11.5 0.4) min−1). Influence various parameters affect photocatalysis performance (i.e., contact time, initial dye concentration, catalyst dosage, solution pH value) also investigated. Radical scavenger reveal superoxide radicals play dominant role process. Collectively, these findings confirm strategic not only enhances overall efficiency but tailors activity towards specific pollutants through radical-mediated pathways.
