“…These intermediates can be further upgraded to hydrogen, gasoline, and other chemicals. Rapid pyrolysis is usually to obtain bio-oil or syngas, which is the focus of most biomass pyrolysis and gasification research and development, but its biochar yield is low. − This method is considered to be the thermal decomposition of low energy density biomass (calorific value < 11 MJ kg –1 ) occurring at moderate temperatures (400–550 °C), very high heating rates (>300 °C min –1 ), and short residence times (0.5–10 s). Table shows the comparison of several biomass char production methods in terms of process parameters and product yield.…”

In the past decades, fossil energy depletion, environmental pollution, and greenhouse gas emissions have resulted in serious health threats and ecological imbalances, which prompt researchers to explore green and sustainable supercapacitor energy storage and conversion systems. Biomass is a promising renewable energy source to use for biomass porous carbon for supercapacitor devices because it is renewable and has abundant reserves, a low price, and low pollution carbon energy. To date, although some reports have screened different biomass precursors, carbonization methods, and activation strategies and mechanisms, a comprehensive evaluation and critical review of the correlation among biomass porous carbon properties, including pore structure and surface chemistry, and electrochemical energy storage performances of supercapacitors are absent from a multidisciplinary assessment perspective. Therefore, in this review, we summarize recent advances in the biomass porous carbon synthesis process focusing on different carbonization and activation strategies, point out the scope of applicability and advantages/disadvantages of these methods in supercapacitor applications, and reveal the reaction mechanisms and limitations for commercial production. Then, the relationships among biomass porous carbon properties, including hierarchical porous structure, surface chemistry, specific surface area, and electrochemical performances of supercapacitors are reviewed in detail, which enables researchers to prepare and design advanced materials in a more rational way and facilitates them to explore more cutting-edge energy storage materials. Finally, two effective techniques including heteroatom doping and composite material construction are reviewed to address the general problem of low supercapacitor energy density. This review demonstrates the great potential of biomass porous carbon with superior properties, provides advanced tailoring and design viewpoints for the application fields of high-performance supercapacitors, and is expected to inspire new exploration and boost the practical commercial applications of biomass-derived hierarchical porous carbon material in more energy storage and conversion fields.

“Liquid‐To‐Solid” Conversion of Biomass Wastes Enhanced by Uniform Nitrogen Doping for the Preparation of High‐Value‐Added Carbon Materials for Energy Storage with Superior Characteristics

Sustainable human development urgently calls for decreasing the cost of energy storage. Continuous massive consumption of dedicated carbon electrode materials with complex internal molecular architectures requires rethinking both the source of materials and the process of their production. Finding an efficient sustainable solution is focused on the reuse and development of waste processing into corresponding high‐value‐added carbon materials. The processing of solid wastes into solid value‐added carbon materials (“solid‐to‐solid”) is relatively well developed but can be a two‐stage process involving carbon architecture rearrangement and heteroatom doping. Processing liquid wastes into high‐value‐added solid material (“liquid‐to‐solid”) is typically much more challenging with the need for different production equipment. In the present study, a new approach is developed to bypass the difficulty in the “liquid‐to‐solid” conversion and simultaneously built in the ability for heteroatom doping within one production stage. Polycondensation of liquid humins waste with melamine (as a nitrogen‐containing cross‐linking component) results in solidification with preferential C and N atomic arrangements. For subsequent thermochemical conversion of the obtained solidified wastes, complicated equipment is no longer required, and under simple process conditions, carbon materials for energy storage with superior characteristics were obtained. A complete sequence is reported in the present study, including liquid waste processing, nitrogen incorporation, carbon material production, structural study of the obtained materials, detailed electrochemical evaluation and real supercapacitor device manufacture and testing.

“…The fifth peak (536.8 eV) was characteristic of oxygen in water molecules. [82,83] The P2p spectrum (Figure 3f ) of ChP-Bp was described by peaks with binding energies at 133.0, 133.2, 134.1, and 136.0 eV. The first peak at 133 eV corresponded to phosphorus chemically bonded to carbon (C─P─C bond).…”

Agriculture is the most massive material circulation activity of humans, with significant annual volumes of production as well as substantial amounts of waste. Transforming agricultural wastes into high‐value‐added products is the key to sustainable development with efficient usage of renewable resources. The present study demonstrates the fine‐tuning of the sugar beet pulp processing to access two types of materials for cutting edge applications—supercapacitors and fuel cells. Alkaline fine‐tuning results in N,O‐doped carbon material (CM) with an advantageous combination of surface area and morphology that allows to achieve high specific capacitance (308 F g−1), and excellent stability (>10 000 charge/discharge cycles). Not limited to the CM preparation and characterization, a real device is created in the present study to demonstrate the efficient usage of the carbon electrode in the form of the assembled coin cell. Acidic fine‐tuning, in contrast, yields a methodology for P,N,O‐doped material and optimizes to form active sites with electrocatalytic activity in the oxygen reduction reaction that is used for electricity production in proton‐exchange membrane fuel cells. The developed approach demonstrates the tuning of functional properties and morphology of CMs under experimentally simple conditions using conventional reagents (KOH and H3PO4) and opens up new directions in the circular biomass usage projects.
