Double-template-regulated bionic mineralization for the preparation of flower-like BiOBr/carbon foam/PVP composite with enhanced stability and visible-light-driven catalytic activity

A novel flower-like BiOBr/carbon foam (CF)/polyvinylpyrrolidone (PVP) composite with a narrow bandgap was fabricated by double-template-regulated bionic mineralization using CF as a hard template and PVP as a soft template. The structure, morphology, and optical properties of the BiOBr/CF/PVP composite were systematically characterized. The photocatalytic activity of the samples was investigated based on the catalytic degradation efficiency of...
