“…The highest diffraction peak for the samples is 1958 and 1358 at ~22.3° for KOH activated and carbonized samples, respectively. The lower diffraction peak means a higher degree of amorphous carbon, which means chemical activation helps to develop more pores on the sample [ 44 ].…”

Sustainable and environmentally friendly activated carbon from biomass materials is proposed to produce supercapacitors from banana peels and has the potential to replace the non-sustainable and hazardous process from either graphite or/and fossil fuels. In order to determine the potential of using banana peel for supercapacitor application, raw banana peel, a bio-waste, was activated both mechanically and chemically to observe the real differences. The sample was activated at 700 °C and chemically activated using KOH. Characterization of activated banana peel was performed using FTIR, DLS, TGA and XRD analytical equipment. FTIR analysis revised the presence of hydroxyl, carbonyl and aromatic compounds on a banana peel cellulose-based carbon. The TGA results proved that 700 oC could be sufficient to totally carbonize banana peel. DLS clearly showed a strong difference between the carbonized and KOH-activated material in particle size distribution. Meanwhile, surface area analysis using BET displayed an increase from 553.862 m²/g to 565.024 m²/g BET in surface area (SBET) when carbon was activated using KOH with a nitrogen isotherm at 77.350K. Specific capacitance was increased from 0.3997 Fg−1 to 0.821 Fg−1, suggesting more than a 100% increase in the specific capacity due to KOH activation, as proved by the cyclic voltammetry (CV) curve. The X-ray diffraction results revealed the patterns of activated carbon. The findings demonstrated the feasibility of using banana peel waste as a low-cost and sustainable material for the preparation of flexible supercapacitor batteries.

“…Fourier transform infrared spectroscopy (FTIR) (Nicolet 6700 Thermo Electron) is used to identify the surface functional groups of the prepared adsorbent. The published procedure by Viena and Nizar 44 was followed in the proximate analysis for the SG adsorbent. Field emission scanning electron microscope coupled with energy dispersive X‐ray spectroscopy (Jeol 6700LV) was used to study the surface morphology of SG and its elemental composition.…”

N‐nitrosodiphenylamine (NDPhA) is soluble in water and highly toxic. Exposure to NDPhA even at low concentrations for a long period can cause several health effects. Hence the removal of NDPhA from aqueous samples using a widely abundant and economical adsorbent is highly challenging. In this study, a highly efficient, eco‐friendly, and low‐cost adsorbent was derived from the dead leaves of Halodule uninervis seagrass (SG) without any chemical modifications. The derived adsorbent was characterized and investigated for the removal of NDPhA from aqueous solutions. The effects of solution pH, contact time, adsorbent dosage, and adsorbate concentration were studied and optimized. The SG adsorbent showed a significant removal efficiency of 83% for NDPhA from wastewater solution using 1 g L−1 adsorbent. The maximum adsorption capacity for SG was found to be 64.84 mg g−1 at neutral pH and room temperature. The adsorption isotherm results fitted with the Langmuir model and followed pseudo‐second‐order kinetics. From the thermodynamic parameters, it has been found that the adsorption of NDPhA onto SG adsorbent is favorable, endothermic, and the chemical adsorption mechanism is predominant. This study indicated that SG adsorbent is reusable and can be easily regenerated and reused at least three times with a slight decrease in its removal efficiency.

“…Aktivasi secara fisik dapat melalui proses karbonisasi pada rentang suhu 300-900 °C serta oksidasi oleh gas O2, dan CO2. Sedangkan aktivasi kimia dilakukan dengan mereaksikan karbon dengan chemical reagent seperti asam fosfat (H3PO4), kalium hidroksida (KOH) dan seng (II) klorida (ZnCl2) [9]. Aktivasi kimia memiliki kelebihan diantaranya dihasilkan pori AC yang lebih besar sehingga meningkatkan luas permukaannya.…”

Penggunaan karbon aktif (activated carbon/AC) semakin luas seperti untuk reaksi kimia, adsorpsi limbah cair dan gas, serta sebagai katalis dalam proses katalitik. AC-tempurung nipah dan AC-kulit pisang kepok telah disintesis dengan aktivator kalium hidroksida (KOH) 0,5 M. Karbonisasi dilakukan dengan furnace pada suhu 300 °C selama 2 jam. Karakterisasi AC dilakukan dengan analisis kadar air, analisis kadar abu, analisis daya serap I2, dan analisis gugus fungsi sebelum proses aktivasi dan setelah proses aktivasi menggunakan FTIR. Nilai kadar air, kadar abu, daya serap terhadap I2berturut-turut adalah 1% ; 9,9%; 1307 mg/g (AC-tempurung nipah) dan 3% ; 7,4% ; 1777 mg/g (AC-kulit pisang kepok), memenuhi kriteria karbon aktif yang telah ditetapkan SNI. Hasil spektra FTIR AC-tempurung nipah dan AC-kulit pisang kepok menunjukkan adanya pergeseran bilangan gelombang serapan gugus –OH setelah aktivasi. Serapan gugus C=C aromatik mengindikasikan telah terbentuknya grafit.
