Abstract EN
Microwave synthesis method is a green chemical process with mild reaction conditions, fast reaction, and low energy consumption.
In this work, an order mesoporous silica material MCM-41 was synthesized by microwave technology.
Functionalized MCM-41 was prepared by wet impregnation with polyethyleneimine (PEI).
XRD, SEM, TEM, DLS, N2 adsorption-desorption, FTIR, and TG were used to characterize the physicochemical properties of samples.
Furthermore, CO2 absorption performance in water in the presence of uncalcined MCM-41 and PEI-MCM-41 nanoparticles was evaluated.
In addition, the mechanisms of enhanced absorption were also elaborated.
The experimental results indicated that the optimum conditions for preparation of MCM-41 were the microwave time of 15 min, microwave temperature of 100°C, and microwave power of 200 W.
Under this condition, MCM-41 with narrow particle size distribution, average diameter of 50 nm, and SBET of 1210.3 m2g-1 was obtained.
The enhancement effect of PEI-MCM-41 nanoparticles was more obvious than that of uncalcined MCM-41.
PEI-MCM-41 as a promoter not only increased the CO2 diffusion rate but also enhanced the adsorption capacity due to the fact that it owns more active sites that may react with CO2.
The CO2 absorption improvement of PEI-MCM-41 (0.1 wt%)/H2O was 25.35% higher than that of water.
