Efficient 3-aminopropyltrimethoxysilane functionalised mesoporous ceria nanoparticles for CO2 capture

This work described the effect of 3-aminopropyltrimethoxysilane (APTMS) functionalization on the mesoporous ceria nanoparticles (MCNs) toward CO2 capture. The MCN and APTMS-loaded MCN (APTMS-MCN) were prepared by the sol-gel and impregnation method, respectively. The functionalization of APTMS on th...
