Composite Material Consisting of HKUST-1 and Indonesian Activated Natural Zeolite and its Application in CO2 Capture

Abstract

AbstractIn this study, composite materials consisting in HKUST-1 [Cu3(BTC)2] (BTC: benzene 1, 3, 5-tricarboxylate) and an Indonesian activated natural zeolite (ANZ) from Klaten, Central Java, were successfully prepared and characterized. The purpose of this research was to determine the effect of the combination of these two materials on the characteristics of the composite as well as to determine its CO2 gas adsorption ability. The composite HKUST-1-ANZ (ANZ@HKUST-1) was synthesized in two different techniques, i.e., solvothermal and sonication method. The obtained materials exhibited X-ray diffractogram characteristics of both HKUST-1 and ANZ. Fourier-transform infrared (FTIR) analysis showed a combination of peaks from HKUST-1 and ANZ, i.e. peaks assigned to carboxylate groups and bonds between Cu-O from HKUST-1, as well as N-H bending and SiO from ANZ. The addition of ANZ to HKUST-1 decreased its surface area and nitrogen sorption capacity. Application of the composites as CO2 capture materials shows their CO2 adsorption capacity is increased (ca. 12%) comparing to the initial materials.
