ABSTRACT
A green composite adsorbent based
on mesoporous silica-gel (SG) and deep eutectic solvent
(DES)
mixture of choline chloride-urea (ChCl:U)
was synthesized as an alternative for carbon dioxide (CO2) adsorption.
The composite adsorbent was prepared by wet impregnation technique
with various ChCl:U
(mole ratio 1:2) content in SG at 5-15% (w/w). Fourier transform
infrared attenuated total reflectance (ATR-FTIR) results showed successful
impregnation of ChCl:U
into SG with the presence of C=O carbonyl amide group stretching,
N-H scissoring bending, CH2 bending and C-N stretching peaks.
Thermal degradation of the adsorbent started with urea at 130°C
followed by ChCl at 300°C. Meanwhile,
nitrogen physisorption demonstrated a decrease in specific surface
areas of the sorbents with increasing ChCl:U
weight percentage due to the blockage of micropores
by ChCl:U. The optimum CO2 adsorption
capacity of 22.3 mg/g was achieved by 10% ChCl:U/SG200,
which was higher than the immobilised
SG200, hence making it relevant to become a green and economical
adsorbent for CO2 capture.

ABSTRAK
Penjerap komposit hijau berasaskan gel silika mesoliang (SG)
dan pelarut eutektik
dalam (DES) kolona
klorida-urea (ChCl:U)
disintesis untuk
penjerapan karbon dioksida (CO2). Penjerap
komposit telah
disediakan dengan teknik penjejalan basah dengan muatan
5-15% (b/b) ChCl:U
(nisbah mol 1:2). Spektrum inframerah transformasi Fourier-pantulan penuh kecil (ATR-FTIR)
membuktikan bahawa
ChCl:U telah berjaya
dijejalkan ke
atas SG dengan kehadiran puncak regangan kumpulan karbonil amida C=O , bengkokan N-H , bengkokan CH2 dan regangan C-N. Suhu degradasi penjerap bermula dengan urea pada 130°C diikuti oleh ChCl
pada 300°C. Analisis
penjerapan fizikal nitrogen menunjukkan penurunan luas permukaan dengan peningkatan peratus berat ChCl:U
disebabkan mikroliang
yang dilitupi oleh ChCl:U. Kapasiti
penjerapan CO2 yang optimum (22.3 mg/g) tercapai dengan menggunakan 10% ChCl:U/SG200 dengan kapasiti penjerapannya lebih tinggi berbanding SG200 tanpa pemegunan,. Ini menjadikannya penjerap hijau yang ekonomi untuk penangkapan
CO2.
