Superior efficiency of BN/Ce2O3/TiO2 nanofibers for photocatalytic hydrogen generation reactions

[Display omitted] •One-dimensional BN/Ce2O3/TiO2 were designed heteroarchitectures by electrospinning.•Structural and morphological properties of nanofibers were fully characterized.•The nanofibers exhibits high visible-light photocatalytic activity with excellent reusability and stability.•BN/Ce2O3/TiO2 nanofibers improve hydrogen production up to 5100 μmol/g for 6 h.•Density functional theory (DFT) has been used to analyze these electronic and phonon transport properties. One-dimensional BN/Ce2O3/TiO2 heteroarchitectures with high visible-light photocatalytic activity have been successfully obtained by an electrospinning technique. The properties of the prepared nanofibers were controlled using different ratios of cerium. The results of XPS characterization revealed that the Ce element is present in the valence state + III on the surface of the TiO2 nanofibers. Rietveld refinement of XRD data reveals that introducing small concentrations of Ce3+ (
