“…9). 141 In most cases the templating method is more effective in introducing mesopores, which is not favorable for CO 2 adsorption as compared with micropores, therefore templating is normally combined with other strategies to achieve higher CO 2 adsorption. For instance, during the sol−gel preparation of phenolic resin, SiO 2 spheres were used as a hard template, and TEOS was added together with resin precursor to introduce extra micropores.…”
