The widespread use of bisphenol F (BPF) as the commonly used alternative to bisphenol A (BPA) in the industry and its hazardous effects on ecological system and human health have attracted widespread attention. In this study, V C -FCN 0.3 hollow nanotube structure with confinement space effects and combined carbon vacancies was constructed by the spatial self-corrosion strategy, which effectively addressed the inherent limitations of conventional carbon nitride and achieved 100% removal rate of BPF within 2 h under visible light. Carbon vacancies not only accelerated the transfer of photogenerated carriers, but also enhanced the adsorption and activation of oxygen that accelerating the production of ·O 2 −, the main active species in this system. In addition, the special spatial structure shortened the mass transfer distance between the target pollutants and the active species. What's more, V C -FCN 0.3 showed excellent, stable, and eco-friendly photocatalytic degradation of bisphenol F over a wide pH range and in five water matrices, contributing effectively to the solution of purification of wastewater containing bisphenol analogues. [Display omitted] • C 3 N 4 hollow tubes with V C were prepared by spatial self-corrosion strategy. • V C promoted light absorption, charge transport, O 2 adsorption and activation. • The unique structure as space confinement accelerated free radical activation. • V C -FCN 0.3 achieved eco-friendly photocatalytic degradation to bisphenol F.
