Photocatalytic degradation of different organic dyes under simulated sun light irradiation found an increasing attention in the recent years. To development high-efficient photocatalyst, this work, we prepared NiFe2O4 nanoparticles by chitosan-assisted route and characterized FT-IR, XRD, UV-Vis, SEM TEM analysis. In addition, photodegradation methylene blue (MB) as a model wastewater has been studied effect important parameters such initial pH solution, catalyst dose, MB concentration time was investigated. The highest 98.99% reported at optimal conditions, 10, photocatalyst dose 0.04 g, 50 mg/L 150 min. kinetics experimental data analysis using Langmuir-Hinshelwood model, result predicted that process obeyed from pseudo-first-order with strong correlation value (R2) 0.9936, k = 0.03082 min−1 t1/2 22.49 Reusability revealed efficiency change (initially) to 95.68% (five cycles). results as-prepared showing great towards dye, ease use, good stability potential be used for other dyes.

Photocatalytic Degradation of Hydrothermally Grown Zinc Oxide Nanorods on a Silver Seed Layer

ACS Omega, Journal Year: 2025, Volume and Issue: 10(6), P. 5708 - 5721

Published: Feb. 4, 2025

Photocatalytic degradation of organic pollutants has emerged as a promising green technology. In this study, we present facile approach to enhance photocatalytic performance by fabricating zinc oxide (ZnO) nanorods (NRs)/silver (Ag) seed layer heterojunctions. The heterojunction fabrication process involves the deposition Ag via spin coating, followed hydrothermal growth vertically aligned ZnO NRs (∼2 ± 0.20 μm length, ∼200 nm diameter) on at 80 2 °C for min. formed metal-semiconductor their contact surfaces, significantly increasing surface-to-volume ratio. appearance double band regime 3.06 eV and 3.37 confirms formation Ag-ZnO efficacy is demonstrated efficiency methylene blue under UV light irradiation, surpassing previous approaches using ZnO-based photocatalysts. This enhanced attributed synergistic effects between Ag, promoting efficient charge separation reducing photocorrosion. research provides designing highly photocatalysts aimed environmental remediation.
