Abstract
Penelitian ini bertujuan untuk menentukan perbandingan mol
terkecil Colloidal Silica yang dapat digunakan untuk sintesis Silika
Amorf Nanopori dan mengetahui kapasitas adsorpsi CO2. Silika Amorf
Nanopori disintesis dengan mengikuti perbandingan molar prekursor
SiO2 : 1.1 NaOH : 0.27 CTAB : 110 H2O. Variasi perbandingan
mol Colloidal Silica (SiO2) yang digunakan adalah 1.0; 0.25; 0.1
mol. Metode yang digunakan untuk sintesis Silika Amorf Nanopori
adalah Hidrotermal pada suhu 120oC selama 24 jam. Padatan yang
dihasilkan dikarakterisasi dengan menggunakan Fourier Tranform
Infrared (FTIR), X-Ray Diffraction (XRD), Adsorpsi-Desorpsi N2
(BET). Perbandingan mol terkecil Colloidal Silica yang masih
dapat digunakan untuk sintesis Silika Amorf Nanopori adalah 0.1
mol. Hasil karakterisasi menunjukan bahwa Silika Amorf
Nanopori dengan perbandingan mol Colloidal Silica terkecil
memiliki luas permukaan terbesar, yaitu 564.863 m2
/g. Sedangkan
Silika Amorf Nanopori dengan perbandingan mol Colloidal Silica
terbesar memiliki diameter pori rata-rata terbesar, yaitu 15.314 nm.
Aplikasi dari Silika Amorf Nanopori pada karya tulis ini adalah
adsorpsi gas CO2 (Karbon Dioksida). Pengukuran adsorpsi gas
CO2 dilakukan secara gravimetri. Sampel Silika Amorf Nanopori
dengan perbandingan mol Colloidal Silica 1, 0.25, 0.1 mol
didapatkan massa CO2 yang terserap berturut-turut adalah 537.7,
250.0, 142.9 mg/g.

This research aims to determine the colloidal silica mol ratio that
can be used for the synthesis of Nanoporous Amorphous Silica and to
measure the CO2 adsorption capacity. Nanoporous Amorphous Silica was
synthesized by following the molar precursor ratio SiO2: 1.1 NaOH: 0.27
CTAB: 110 H2O. The mol ratio variation of Colloidal Silica (SiO2) is 1.0;
0.25; 0.1 mol. The method used for the synthesis of Nanoporous
Amorphous Silica was hydrothermal methode at 120oC for 24 hours. The
resulting solid was characterized using Fourier Transform Infrared
(FTIR), X-Ray Diffraction (XRD), N2 Adsorption-Desorption (BET).
The smallest mol ratio of Colloidal Silica to synthesized Nanoporous
Amorphous Silica is 0.1 mol. The characterization results showed that the
Nanoporous Amorphous Silica with the smallest mol ratio of Colloidal
Silica has the largest surface area. The surface area is 564,863 m2
/g.
Meanwhile, Nanoporous Amorphous Silica with the largest Colloidal
Silica mol ratio has the largest average pore diameter, which is 15,314
nm. The application of Nanoporous Amorphous Silica in this paper is the
adsorption of CO2 gas (Carbon Dioxide). CO2 gas adsorption
measurements were carried out with gravimetric methode. Nanoporous
Amorphous Silica samples with mol ratio of Colloidal Silica 1, 0.25, 0.1
mol, it was found that the weight of CO2 adsorbed was 537.7, 250.0,
142.9 mg/g, respectively.
