摘要:
Disclosed herein is a method of surface-functionalizing a porous organic-inorganic hybrid material or a organic-inorganic mesoporous material, in which organic substances, inorganic substances, ionic liquids and organic-inorganic hybrid substances are selectively functionalized on the coordinatively unsaturated metal sites of a porous organic-inorganic hybrid material or organic-inorganic mesoporous material, and thus the porous organic-inorganic hybrid material can be used for adsorbents, gas storage devices, sensors, membranes, functional thin films, catalysts, catalytic supports, and the like, and the applications of the surface-functionalized porous organic-inorganic hybrid material prepared using the method to catalytic reactions.
摘要:
The present disclosure relates to a method for recovering styrene monomers from waste polystyrene, and more specifically, to a method for recovering styrene monomers from waste polystyrene, in which the waste polystyrene is depolymerized using an eco-friendly solvent and a potassium-containing carbonate depolymerization catalyst to suppress the generation of ethylbenzene, etc. generated as by-products in a styrene monomer recovery step, and thus the styrene monomers can be recovered in high yield.
