Abstract:
A pseudo-hard-template, obtained by the self-assembly and disassembly of Victoria Pure Blue (VPB), was rationally designed to synthesize C-SiO2 hollow nanostructures (h-C-SiO2). The hollow nanostructures show unprecedented perfluorooctanoic acid (PFOA) removal performance with an adsorption capacity of 790.71 mg g-1 and fast adsorption kinetics of 4899.37 g mg-1 h-1.
