Abstract

The increasing discharge of dye-containing wastewater, particularly from the textile industry, poses serious environmental and health hazards due to the persistence, toxicity, and carcinogenic nature of many dye compounds. Conventional treatment methods often fall short in terms of efficiency, cost, or environmental sustainability. Among advanced oxidation processes (AOPs), photocatalysis has emerged as a promising and eco-friendly approach for the degradation of organic pollutants. Titanium dioxide (TiO₂), a widely studied semiconductor photocatalyst, has shown high potential due to its chemical stability, non-toxicity, availability, and strong oxidative power under ultraviolet (UV) light. This study explores the fundamental mechanisms of photocatalysis, including photon absorption, charge carrier generation, redox reactions, and the formation of reactive radicals (•OH, O₂•⁻) that degrade dye molecules into harmless end-products. Emphasis is placed on the suitability of TiO₂ as a benchmark material for photocatalytic applications, as well as its modifications to enhance visible-light response. Furthermore, recent studies on the photocatalytic removal of dyes like methylene blue using TiO₂/UV-C systems are discussed to highlight its practical efficacy. Overall, TiO₂-based photocatalysis represents a highly viable solution for wastewater remediation, offering a path toward sustainable and efficient pollutant degradation.
