Photoelectrocatalytic Degradation of Rhodamine B in the Presence of TiO₂-BiVO₄.

ABSTRACT: The discharge of printing and dyeing wastewater has become a key concern in global water pollution control due to its high pollutant concentration, dark color, refractory biodegradability and toxic characteristics. Photoelectrocatalytic (PEC) technology has gained widespread attention as it can effectively treat refractory organic pollutants. In this study, titanium dioxide (TiO₂)-bismuth vanadate (BiVO₄) composite materials were synthesized through the sol-gel/solvothermal hybrid method, and layered heterojunction structures were fabricated via sol-gel precursor preparation followed by spin-coating deposition. The PEC degradation efficiency of rhodamine B (RhB) was systematically evaluated under varying operational conditions in the presence of TiO₂-BiVO
