摘要：It can be larger: A facile self-assembly/solvothermal approach to synthesize monodispersed, large-pore (>12 nm) silica nanospheres (LPSNs) with ordered, accessible, and interconnected pore channels has been successfully developed by utilizing an amphiphilic block copolymer (polystyrene-b-poly (acrylic acid), PS-b-PAA) as pore template and cetyltrimethylammonium bromide (CTAB) as structure-stabilizing agent.
