The development of hollow tubular nanostructured photocatalysts has been identified as a research priority in the realm of photocatalysis. However, fabricating bismuth vanadate (BiVO4) nanotubes, which are effective photocatalysts for water purification, remains challenging. The present work effectively produced uniform single-phase BiVO4 nanotubes using a template-free approach. As a consequence of the unique hollow tubular structure, the prepared sample exhibited a high visible light absorption capacity and a large specific surface area, which improves photocatalytic efficiency. Within 120 min, a degradation rate of up to 70 of tetracycline hydrochloride was reached under visible light. This study will enrich the morphological diversity of BiVO4 photocatalyst and promote the development of BiVO4-based photocatalysts.
