Abstract
The formation of a heterojunction between two semiconductor photocatalysts, consisting of narrow band gap oxide, is essential for effectively segregating and transferring charge carriers. For instance, β-Bi2O3 has garnered attention for its excellent structural, optical, dimensional anisotropy, and electrical properties. B-rGO's 2D sheet-like structure is ideal for scaffolding β-Bi2O3 nanoparticle development under various reaction conditions. This study effectively produced the β-Bi2O3/B-rGO binary system using morphology modification and energy band structure design. This article emphasizes β-Bi2O3/B-rGO interface engineering and heterojunction design, followed by photocatalytic applications for ciprofloxacin degradation. The photocalytic activity of this β-Bi2O3/B-rGO photocatalyst is ∼ 1.2 times greater than of pure β-Bi2O3. This article envisages the development of effective β-Bi2O3/B-rGO heterostructures for multiscale applications.
