“…Intensitas pada D-band yang relatif rendah menunjukkan bahwa CNF mengandung sedikit karbon dalam hibridisasi selain sp 2 (Mitchell et al, 2015). Intensitas pita D biasanya 100 kali lebih kecil dari pada pita G. Puncak D-band yang besar dibandingkan dengan intensitas puncak G-band biasanya menunjukkan adanya karbon amorf (Saucedo-Jimenez et al, 2018).…”

Karbon memiliki kemampuan untuk membuat jaringan ikatan hibridisasi sp, sp‒sp2, sp2, sp3, dan sp2‒sp3,sehingga karbon terdapat dalam banyak bentuk alotrop seperti grafit, diamond, graphene, nanofiber, nanofoam, dan nanotube. Carbon nanofoam (CNF) terbentuk dari atom karbon yang terikat secara sp2 dan sp3. CNF memiliki struktur sel terbuka yang saling berhubungan, densitas yang sangat rendah, stabilitas termal yang tinggi, dan porositas yang tinggi. CNF dapat diperoleh dengan menggunakan berbagai metode seperti chemical vapor depositon, laser ablsasi, arc-discharge, dan pirolisis. Sintesis dengan berbagai jenis sumber karbon dan keadaan eksperimen menghasilkan material yang memiliki berbagai ukuran, luas permukaan, dan strukturnya. Struktur CNF terdiri dari dua jenis berdasarkan pola tepi strukturnya yaitu zigzag dan armchair. Hasil karakterisasinya menunjukkan bahwa CNF lebih banyak mengandung karbon dengan hibridisasi sp2 dengan struktur yang berinterkoneksi satu sama lain dan memiliki densitas yang sangat rendah. Selain itu, material ini juga memiliki pori dalam ukuran mesopori dan luas permukaan yang tinggi. Sifat unik yang dimiliki oleh CNF berpotensi diaplikasikan dalam berbagai bidang seperti filter, superkapasitor, dan energy storage. Synthesis of Carbon Nanofoam and Its Characteristics. Carbon can create sp, sp‒sp2, sp2, sp3, and sp2‒sp3 hybridized bond networks, which make carbon in many allotropes forms such as graphite, diamond, graphene, nanofiber, nanofoam, and nanotubes. Carbon nanofoam (CNF) is formed by sp2 and sp3 bonded carbon atoms. CNF has an interconnected open-cell structure, very low density, high thermal stability, and high porosity. CNF is obtained using several methods, such as laser ablation, arc-discharge, chemical vapor deposition, and pyrolysis. Synthesis with various types of carbon sources and experimental conditions resulted in materials having various sizes, surface areas, and structures. The structure of CNF consists of two edge pattern types, including zigzag and armchair. The characterization results show that CNF contains more interconnected carbon with sp2 hybridization and has a very low density. In addition, this material also has pores in the mesoporous size and high surface area. The unique properties of CNF provide potential applications in various fields, such as filters, supercapacitors, and energy storage.

Carbon nanofoam is one of the carbon allotropes having sp2 and sp3 hybridized carbon, with graphite or non-graphite-like structures, a stable framework, and very low density. This study aims to synthesize carbon nanofoam by chemical vapor deposition using an Agar/NaCl catalyst and Ar/C2H2 gases at 700°C. The success of the synthesis was analyzed using FTIR and SEM-EDX analysis. The carbon nanofoam obtained was hydrophobic. The FTIR spectra show absorption at wavenumber 3445, 2921, and 1527 cm−1, respectively, indicating the presence of hydroxyl groups, aliphatic C-H, and C=C stretching. However, its FTIR spectra indicate the absence of hydrophilic groups, such as covalent-bonded oxygen-containing functional groups. The SEM image shows the interconnected framework with irregular pores. The elemental analysis using EDX shows that the prepared CNF contains C and O elements of 92.45 and 7.6%, respectively. The prepared carbon nanofoam shows ascorbic acid slowing release in its drug carrier application due to its large porosity and surface area.
