Abstract
Penelitian ini bertujuan untuk mensintesis karbon tertemplat zeolit-X (KTZ-X) yang memiliki struktur teratur, mikroporositas tinggi dan kapasitas adsorpsi CO2 tinggi dengan dilakukan variasi penambahan sukrosa. Rasio massa sukrosa/zeolit-X yang digunakan adalah 0,5; 0,75; 1 dan 1,25. Hasil analisis menunjukkan bahwa KTZ dengan rasio massa sukrosa/zeolit-X 0,5 berhasil mereplika negatif struktur zeolit-X, yang dikonfirmasi pada 2"θ" = 6° dan mikrograf SEM dengan morfologi menyerupai kristal oktahedral zeolit-X. KTZ-X 0,5 juga menunjukkan mikroporositas tertinggi dengan ukuran pori rata-rata 2,55 nm dan volume mikropori 0,149 cm3/g. Hasil uji adsorpsi CO2 dengan metode gravimetri pada suhu 30 °C dan tekanan 1 bar menunjukkan KTZ-X 0,5 memiliki kapasitas adsorpsi tertinggi mencapai 33,55 %berat. KTZ-X 0,75; 1; dan 1,25 memiliki kapasitas adsorpsi masing-masing mencapai 3,82; 27,23; dan 26,48 %berat. Hasil ini menunjukkan adanya pengaruh penambahan sukrosa terhadap mikroporositas dan kapasitas adsorpsi CO2 pada KTZ-X.

The aim of this research is to synthesis zeolite-X templated carbon (ZTC-X) with an ordered structure, a high microporosity and a high CO2 adsorption capacity at various amount of sucrose. The mass ratio of sucrose/zeolite-X was varied at 0.5; 0.75; 1; and 1.25. The results shows that ZTC-X, with the mass ratio of sucrose/zeolite-X 0.5, possess an ordered negative replica structure of zeolite-X. It was confirmed by XRD peak at 2"θ" = 6° and the image of SEM shows that particles have an octahedral crystal structure like zeolite-X. Besides, the ZTC-X 0.5 exhibits higher microporosity, according to average pore size of 2.55 nm and micropore volume of 0.149 cm3/g. The ZTC-X 0.5 also has a higher CO2 adsorption capacity (33,55 wt%) by gravimteric method. Meanwhile, The CO2 adsorption capacity of ZTC-X 0.75; 1; and 1.25 are 2.82; 27.23; and 26.48 wt%, respectively. It indicates that the various amount of sucrose effecting a microporosity and CO2 adsorption capacity of ZTC-X.
