“…The detected peaks were found in the range of wavenumbers from 2960 to 2850/ cm for the C-H bond stretching in aliphatic formation, which is an indication of the presence of cellulose, hemicellulose, and lignin in the precursor. The wavelength for the peak was found to be 2948/cm for 400 °C biochar and decreased to 2935/cm for 600 °C biochar (Antonangelo et al 2019;Reza et al 2019b). Peaks with the range of 2830-2670/cm was for the C-H Bending in aliphatic formation.…”

“…In this stage, the wavenumber has been increased from 2674 to 2688 for the biochar of 400-600 °C (Özçimen and Ersoy-Meriçboyu 2010; Antonangelo et al 2019). The Crests for the area from 1910 to 2360/cm wavenumbers represent C=O stretching in the ketene (El-Hendawy 2006;Reza et al 2019b). Peaks from 1610 to 1590/cm are for C=C stretching in hemicelluloses mainly.…”

“…The proximate analysis of the Pennisetum purpureum grass sample shows the moisture content (5.93%), volatile matter (69.44%), fixed carbon (16.81%), ash content (7.82%) and ultimate analysis shows the carbon (43.23%), hydrogen (5.80%), nitrogen (1.17%), sulfur (0.11%), oxygen (41.76%) (Reza et al 2019b). In pyrolysis, the biochar yield was 35.13%, 28.41% and 23.02% for the pyrolysis temperature of 400 °C, 500 °C and 600 °C, respectively, which was measured by the mass balance of the remaining solid weight inside the reactor.…”

“…It is extremely essential to develop the technologies for saving the world from greenhouse gas pollution and from invasive plants aggressiveness. Biofuel technology is one of the best methodology to manage the invasive plants by converting them into bioenergy which can reduce the greenhouse gas (GHG) emission (Reza et al 2019b, a). Pyrolysis, gasification and hydrothermal carbonization are the major processes to convert biomass into biochar, bio-oil, and biogas (Hidayat et al 2018;Radenahmad et al 2020).…”

Pennisetum purpureum is one of the most invasive perennial grasses of the Poaceae family, which are abundant in southeast Asia including Brunei Darussalam. The pyrolysis process at a slow heating rate proved to be highly promising for biochar production. The production and characterization of different Pennisetum purpureum biochars have been investigated at the pyrolysis temperatures of 400 °C, 500 °C and 600 °C with a heating and nitrogen flow rate of 5 °C/min and 0.5 L/min, respectively. The observed higher heating values were 22.18 MJ/kg, 23.02 MJ/kg, 23.75 MJ/kg, and the alkaline pH were 9.10, 9.86, 10.17 for the biochar at 400 °C, 500 °C, 600 °C temperatures, respectively. The water holding capacity was one hundred percent for all biochars and continued to increase for higher pyrolysis temperature. SEM images show that the porosity of the biochars has been enhanced with increased temperatures due to the rearrangement of crystallinity and aromaticity. On the other hand, the yields of biochar have been decreased from 35.13% to 23.02% for the increase of pyrolysis temperature from 400 °C to 600 °C. Energy dispersive X-ray analysis shows that the O/C atomic ratios were 0.15, 0.08 and 0.06 for the biochar of 400, 500 and 600 °C which validates the improvement in heating values. FT-IR analysis revealed that the available functional groups in the biochars were CO , C=C, and C-H. Thermogravimetric analysis (TGA) under pyrolysis condition showed residue of 46.56%, 51.13% and 55.67% from the biochar at 400, 500, and 600 °C, respectively. The derivative thermogravimetry (DTG) graph indicates that the degradation rate is higher for 400 °C biochar than the 600 °C biochar.

Activated carbon (AC) is an extremely porous carbonaceous adsorptive substance which has a rigid carbon matrix with high surface area and broad functional groups. The structure is connected by chemical bonds; arranged irregularly, generating a highly porous arrangement of corners, crevices, claps, and cracks between the carbon layers. Activated carbons are produced high-temperature and chemical activation of waste biomass. The pores in the lattice network of activated carbon permit the removal of impurities from gaseous and liquid medium through adsorption. At present, the COVID-19 disease is the prime concern around the whole world because of its exponential infections and death rate. There is no medicine for this virus, and protection is the only remedy to survive from this contagious disease. Using a face mask is one of the best methods to get rid of COVID-19. The mask combined with activated carbon can be beneficial for adsorbing and disinfecting the virus as it is the versatile adsorbent for the elimination of the organic, inorganic, and pathogenic contaminants.
