C–SiO2 hollow nanostructures by a pseudo-hard-template route for outstanding perfluorooctanoic acid removal
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.
