摘要：
A facile route for the synthesis of synthetic hectorite hollow microspheres (SHHMS) having a diameter of 4-6 mu m and wall thickness of 30-50 nm has been demonstrated. Carbon spheres obtained from the autogenic pyrolysis of polypropylene have been utilized as a template for the synthesis of SHHMS. The formation of the hectorite architecture was confirmed by X-ray diffraction and infrared spectroscopy. The scanning and transmission electron microscopic studies reveal their spherical and hollow nature. The morphology of the obtained product was dependent on the amount of carbon spheres template. The obtained SHHMS showed the mesoporous textural property with enhanced carbon dioxide adsorption capacity (19.2 cm(3)/g) as compared to that of calcined hectorite (15.3 cm(3)/g) at 303 K.
