Enhanced photocatalytic degradation of Cotton red dye using boron doped TiO2

Abstract

Photocatalytic degradation is an effective process for eliminating organic pollutants from wastewater, which is essential for maintaining ecological and environmental safety. Photocatalysis, an advanced oxidation technique, has gained significant attention for water treatment in recent years. Boron-doped titanium dioxide (B/TiO₂) nanoparticles were synthesized using a modified sol-gel method under ambient conditions. The nanoparticles were analyzed for crystal structure, thermal stability, bandgap, surface morphology, particle size, molar ratio, recombination behavior of photogenerated charge carriers, and charge transfer properties. This study reports the synthesis of B–TiO₂ nanoparticles and their efficient photocatalytic performance. The objective was to introduce boron as a dopant to enhance the photocatalytic activity of TiO₂, particularly in the visible light region.
