Pengaruh Luas Permukaan Spesifik terhadap Kapasitansi Spesifik Elektrode Zeolit Akibat Variasi Suhu Kalsinasi
Abstract: The effect of
specific surface area to the specific capacitance of electrode zeolite with variation
of calcintion temperatures. This study describes the potential of zeolite as a
supercapacitor electrode which aims to determine the effect of surface area on
the specific capacitance of the zeolite. Zeolites was synthesized from a
mixture of silica based rice husk and alumina using sol gel methode and was
calcined at 150, 250, 350, 450, 550, and 650oC. The XRD result showed already
formed alumina and silica phases for each calcinations temperature and the
temperature of 350oC has formed gmelinite phase which marks have been formed
zeolite. The specific capacitance increase in the specific surface area at
90.69 - 150.01 m2/g, and occurred saturation of specific capacitance at a
specific surface area of 150.01 m2/g. The highest of specific capacitance is at
specific surface area of 150.01 m2/g is equal to 8.13x10-3 F/g obtained from
zeolites with calcination temperature of 650oC. Based on this value, the
zeolite can be used as a supercapacitor electrode material.
