A Review of Visible-Light-Active Zinc Oxide Photocatalysts for Environmental Application

Catalysts, Journal Year: 2025, Volume and Issue: 15(2), P. 100 - 100

Published: Jan. 22, 2025

Zinc oxide (ZnO) photocatalysts have emerged as a promising material for environmental and energy applications due to their exceptional photocatalytic properties. Initially recognized efficiency under ultraviolet (UV) light, recent advancements focused on enhancing ZnO’s visible light activity (VLA) address its inherent limitations. This review provides an overview of structure, electronic properties, mechanisms. Various strategies modifying ZnO harness including metal non-metal doping, dye sensitization, semiconductor coupling, are discussed. Special emphasis is placed the mechanisms behind absorption reactive oxygen species (ROS) generation, deduced through physicochemical photoelectrochemical analyses. The in remediation comprehensively explored, particularly water treatment, disinfection, air purification. degradation pollutants, persistent organic compounds, pharmaceuticals, dyes, pesticides, using reviewed compared with conventional UV-activated materials. underscores potential efficient sustainable solution

Abstract Single ZnO (NM1), MnO 2 (NM2) nanoparticles, and –g‐C 3 N 4 –ZnO (NM4) nanocomposite were synthesized by the sol–gel method, whereas g‐C (NM3) was polymerization of urea. The as‐synthesized materials characterized thermogravimetric‐differential thermal (TGA‐TDA), Fourier transformer (FTIR), X‐ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), high‐resolution transmission (HRTEM).The bandgap NM4 lower than those NM1, NM2, NM3 photocatalysts, which is applicable in visible region. photocatalytic activities studied under light radiation. efficacy composite 5, 3.4, 3‐fold higher materials. This enhancement might be ascribed to synergistic effect. Besides, degraded 94% methylene blue (MB) 81% real sample. rate constant ( k ) for NM3, also resulted 0.00327, 0.0046, 0.0056, 0.0156 min −1 , respectively. reusing carried out four sequential rounds 94%, 92.6%, 91%, 89% degradation efficiency 1st, 2nd, 3rd, 4th round, result suggests that cost‐effective stable.

Time-Dependent Growth of ZnO Nanowires: Unveiling Antibacterial and Photocatalytic Properties

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

This study investigates the synthesis, characterization, and functional properties of well-aligned zinc oxide (ZnO) nanowires (NWs) obtained by a two-step hydrothermal method. ZnO NWs were grown on silicon substrates precoated with seed layer. The growth process was conducted at 90 °C for different durations (2, 3, 4 h) to examine time-dependent evolution nanowire properties. A comprehensive characterization performed using several analytical techniques. Scanning electron microscopy (SEM) revealed morphological progression, specifically tracking changes in length diameter as function time. Ultraviolet (UV)–visible spectroscopy employed determine optical band gap, while photoluminescence (PL) analysis provided insight into concentration structural defects its growth. photocatalytic efficiency evaluated through degradation organic dye methylene blue (MB) under UV light irradiation (365 nm). kinetic MB monitored each time, non-purgeable carbon (NPOC) providing detailed perspective activity over antibacterial tested against Pseudomonas putida, Gram-negative bacterium, synthesized antimicrobial agents. release ions (Zn2+), key factor mechanism, quantified inductively coupled plasma (ICP) sample.
