摘要: Recently, there has been significant research interest toward sustainable chemical synthesis and processing of nanomaterials. Human urine, a pollutant, requires energy intensive steps prior to releasing into rivers oceans. Upcyling urine proposed practiced as process in the past. Doping is one foremost processes elevate functionality nanomaterials depending on applications it sought for. Phosphorus doping TiO2 over decade now, that chiefly done using acidic precursors. Here we demonstrate, upcycling for phosphorus lattice. Upon changes morphology, surface chemistry band gap studied detail compared with undoped prepared deionized water instead urine. X-ray photoelectron spectroscopy confirmed P was replacing Ti lattice exists P5+ state quantified concentrati...
