Abstract
Polybenzoxazine (PBZ) xerogels have been synthesized via quasi solventless method and coated with silver nanoparticles using the layer-by-layer (LbL) deposition method. After coating, the samples were carbonized at 800 °C to obtain high surface area porous carbon materials to be used for CO2 storage. Evidences of the successful layer-by-layer deposition of the coating was provided by UV-vis and ATR-FTIR spectroscopy and the silver nanoparticles top layer was confirmed by SEM-EDX, TEM, XRD, and XPS. Results showed that the samples coated with silver nanoparticles displayed an increased CO2 capacity from 3.02 to 3.39 mmol g−1 when compared with the plain carbon PBZ. The LbL method for the modification of the pore surface in porous PBZ is simple and allows the facile tuning of the inner PBZ pore's surface chemistry with metallic nanoparticles that could be enhanced CO2 storage capacity. © 2017 Wiley Periodicals, Inc.
