Abstract

This study presents a green and eco-friendly approach for synthesizing ZnO nanoparticles using the marine macroalga Turbinaria Ornata (TO) as a capping agent, which demonstrates remarkable photocatalytic and electrochemical properties. The biogenic zno achieved an outstanding 88% degradation of Methylene blue (MB) dye under solar irradiation within 90 min, outperforming conventional ZnO catalysts. Reactive oxygen species, specifically hydroxyl radicals (·OH) and superoxide anions (O₂^–), were identified as key contributors to the degradation process, highlighting the material’s efficiency. Notably, the biogenic ZnO maintained high stability with 84% degradation after four cycles, showcasing excellent reusability for long-term applications. This work emphasizes the novelty and superiority of using marine-derived zno for photocatalytic applications, offering a sustainable, cost-effective solution for wastewater treatment and energy storage, with significant advantages compared to existing methods.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
