Facile Synthesis of Mesoporous Silica for Separation of Coalbed Methane

2014 Asian Journal of Chemistry  
Mesoporous silica as potential adsorbent for separation of coalbed methane was prepared by using one anionic surfactant containing poly(ethylene oxide) group as template in a facile method. Small angle XRD, TEM and N2 adsorption-desorption isotherms were carried out to confirm the final product. From the results of characterizations, the diameters of the spherical particles have a narrow range of 100-130 nm and the mesoporous sizes are in 2-4 nm. In addition, the average pore size is 2.98 nm,
