Phosphorus-rich microorganism-enabled synthesis of cobalt phosphide/carbon composite for bisphenol A degradation through activation of peroxymonosulfate

•Recovery and utilization of phosphorus from microorganism for Co2P synthesis.•Reducing gases detected by TG-MS favoring phosphate reduction to phosphide.•High activity and good recyclability for BPA degradation over Co2P/C composite.•Low ecotoxicity of BPA degradation solution toward microalgae growth.
