Preparation and Characterization of Attapulgite-KH550 Nanocomposites and their Application to Methane Absorption

Article Preview

Abstract:

Attapulgite is a natural rod-like nanomaterial. The surface of natural attapulgite nanoparticles was cleaned, modified with silane coupling agent 3-aminpropyltriethoxysilane (KH550). The structure and morphology of the modified attapulgite were characterized by infrared spectroscopy, scanning electron microscope (SEM). The methane absorption capacity of the modified attapulgite was recorded by intelligent gravimetric analyzer. SEM revealed that 3-aminpropyltriethoxysilane was modified on the surface of rod-like attapulgite nanoparticles. The 3-aminpropyltriethoxysilane can obviously increase the methane absorption capacity of the nanoparticles almost about twice. This result may provide the attapulgite nanoparticles a new way to industrial application.
