“…However, in this case, the material produced at 800 °C exhibited electrical conductivity similar to commercial carbon black. Similarly, Bhakare et al produced a conductive material by carbonizing cow dung at 800 °C, finding similar trends between temperature and biocarbon properties over a range of temperatures from 400–1000 °C, followed by washing with aqueous HF. Despite very high oxygen content (>20 wt %), the material produced at 800 °C was useful for producing a conductive black paint.…”

“…Despite very high oxygen content (>20 wt %), the material produced at 800 °C was useful for producing a conductive black paint. A key difference between the process used by Snowdon et al 102 and those used by Wang et al 103 and Bhakare et al 104 is the lack of an aqueous processing step that will significantly reduce the ash content of the biocarbon product. Although ash content was not reported in all of these studies, Bhakare et al 104 reported that the HF wash completely removed inorganic impurities.…”

Industrial carbons are a category of high purity carbon (>95 wt %) materials that are solid at room temperature, produced in bulk as refinery byproducts, and subsequently used in a wide variety of applications. The most dominant industrial carbons are calcined coke, coal tar pitch, carbon black, and graphite. The manufacturing sector consumes a large majority of industrial carbons as electrode materials, carbon binders, tire reinforcement fillers, and ink components and constitutes one of the largest contributors to greenhouse gas emissions worldwide. Thermochemical conversion of biomass offers promising pathways for both the integration of drop-in fuels with refinery infrastructure and for the production of carbonaceous solid materials. Conversely, over the past two decades, most biofuels efforts focused on fuel production technologies with high-value small molecule chemicals as coproducts. This review summarizes recent progress toward developing biobased industrial carbons, particularly as coproducts from thermochemical conversions of biomass. Pyrolysis and gasification produce liquid and solid products in varying yields; biocarbons from either stream currently must compromise between adequate yield and adequate quality. While metals can be removed post-synthesis, there exist opportunities for improvement of biocarbon quality, including using deashed biomass and/or process modification beyond standard pyrolysis conditions. Improving calcined coke and tar pitch properties (density/porosity and softening point/coking value, respectively) will likely follow by departing from standard biomass conversion parameters. Although markets exist for biobased graphite, current products of high quality will require significant research into scale-up strategies.

A naive one-pot strategy developed to prepare high-performance trinary based material as an energy storage material for supercapacitor. Herein, we have systematically studied and established an effortless and proficient synthetic method to formulate reduced graphene oxide (rGO)/polyaniline (PANI)/ manganese dioxide (MnO 2) (RPM) trinary material in one-step without any additional oxidizing/polymerizing agent and acidic condition. The approach of "one arrow two targets" have employed to synthesize trinary based nanocomposite. For the first time, we have synthesized this trinary material in one step. Initially, in-situ synthesized carbonic acid was consumed as a reducing agent to reduce the graphene oxide (GO) as well as it provided acidic condition for the formation of MnO 2 and polymerization of aniline. Secondarily, MnO 2 particles synthesized from KMnO 4 precursor, which acted as an oxidizing agent to polymerize aniline in the presence of carbonic acid. The material reflected the electrical double layer capacitance as well as pseudocapacitance of RGO and PANI/MnO 2. The material exhibited the maximum specific capacitance, 592 F/g at 1 A/g current density corresponds to excessive specific energy and specific power 66.6 Wh/kg, 1800 W/kg, respectively. This familiar route of direct production of graphene with the synergism of PANI-MnO 2 on carbon can be useful for largescale fabrication of nano-carbon material for diverse applications including energy storage application.
