“…From the biomass conversion products, biochar has attracted attention globally due to its huge surface area, functional groups, pore structure, and high inorganic substance (Huang et al 2019). Biochar can be applied as the adsorbent of pollutants in air and water (Qaisrani et al 2018;Huang et al 2019), as a catalyst for removing tar and produce biodiesel (Konwar et al 2014), as an improvement to the soil (Oladele et al 2019), in fuel cells (Chen et al 2019;Afroze et al 2019), super-capacitors (Afif et al 2019), energy production (Meng et al 2019), and greenhouse gas reduction (Chen 2019). Biochar can also be preserved in the soil for more than a hundred years (Palansooriya et al 2019).…”

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.

Biochar is a stable carbon rich by-product synthesized through pyrolysis of plant and animal based biomass, and nano-biochar material has gained increasing attention due to its unique properties for environmental applications. In the present study, a simple cost-effective method for the synthesis of biochar nanoparticles through hydrothermally using agricultural residuals and by-products was developed. Both soybean straw and cattle manure were selected as the feedstock to produce the bulk-biochar. The synthesis procedure involved the digestion of the bulk-biochar with concentrated nitric acid and sulfuric acid in a high pressure condition using a hydrothermal reactor. The suspension was isolated using vacuum filtration with 0.22-μm membrane followed by drying at 65 °C in an oven. Scanning electron microscopy results revealed that both of the biochars had a well-developed porous structure following pyrolysis. Both transmission electron microscopy and the dynamic light scattering results of the hydrothermally treated biochar indicated that the soybean straw and cattle manure biochar nanodots had an average of 5-nm and 4-nm in size, respectively. Overall two raw materials produced 8.5–10% biochar nanodots. The present method presents a simple, quick and cost-effective method for synthesis of biochar nanodots. The method provided a useful tool discovering the applicability biochar nanodots for environmental applications. • Nano-biochar formation from bulk-biochar using hydrothermal reactor • Evaluate nano-biochar's environmental fate and behavior in soil and water • Synthesize multifunctional adsorbent using nano-biochar as primary material

Rice as a sensitive crop that usually affected by many harmful environmental stresses. Numerous policies are followed to increase plant growth-tolerance under abiotic-stresses in various plant species. The attempts to improve crop tolerance against abiotic stresses via common breeding method are needed to follow a long-term, and may also be non-affordable, these are due to the existing genetic variability of the plant. Current review analysis existing knowledge gaps, challenges, and opportunities in the biochar application as a beneficial and pyrogenic-C, material. Consequently, a review of the literature with a high focusing on the multiple beneficial effects of using biochar on tolerance and productivity of rice in abiotic stresses is needed. This review provides a summary of those efforts that would be beneficial in reducing inconvenienced abiotic-stresses, and also how using biochar could increase rice tolerance and production through the supporting of plant growth regulator's roles. Accordantly, present review findings showed that biochar is a great amendment and consisting of principally organic rich-C matter, which has multiple benefits on improving soil physicochemical and biological properties as well as increasing rice tolerance and its productivity through enhancing plant hormones roles under abiotic stressed conditions (heat/cold temperature, drought, salinity, heavy metal, and climate change stresses). Nevertheless, it is anticipated that further researches on the benefits of biochar will increase the comprehension of interactions between biochar and plant growth hormones, to accelerate our attempts for improving rice tolerance and productivity, under abiotic-stress conditions.
