Abstract

The synthesis of mesoporous silica via a dual-template surfactant, i.e., a block copolymer (Pluronic® P123) combined with one other surfactant, e.g., BASF products (Pluronic® F68, and F127, and polyethylene glycol compounds (PEG200, PEG600, and PEG 1500) to enhance CO2 capture is described. The mesoporous silica synthesized by combining Pl23 with F68 and with PEG 1500 showed better adsorption capacity of CO2 than that synthesized by the single surfactant, Pl23. CO2 adsorption increased in the order of P123, P123/F68=1:1, P123/F68=3:1, and P123/F68=1 :3. The material synthesized via Pl23:F68=1 :3 showed the best adsorption capacity at 41 mg CO2/g-adsorbent, for CO2, due to the higher surface area and microporosity. The mesoporous silica synthesized via P 123 :F68= 1 :3 showed excellent CO2 adsorption capacity, and was enhanced by nearly 10 mg CO2/g-adsorbent. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).
