Phenylene-bridged mesoporous organosilicas
WebApr 25, 2014 · A metal-ion-assisted assembly approach to synthesize disulfide-bridged periodical mesoporous organosilicas with high sulfide contents and efficient adsorption. Appl. Surf. Sci. 256, 5334–5342 ... WebAbstract The pore walls of phenylene-bridged periodic mesoporous organosilicas (B-PMOs) can be crystal-like or amorphous depending on the synthesis conditions. Here, spin-probe electron paramagnetic resonance (EPR) is used to monitor the adsorption of nitroxide radicals on three types of B-PMO with varying pore size and wall characteristics.
