“…They reported the synthesis of N‐doped carbon‐based aerogels from glucose, d ‐glucosamine and/or N ‐acetyl‐ d ‐glucosamine, and phenolic compounds (phloroglucinol and cyanuric acid), which led to porous monolithic aerogels (450 m 2 g −1 ) with 3–5 at% nitrogen content . Later, soybean flour was added to the procedure as a nitrogen source and pore‐directing agent . In addition, an in situ synthesis of N,S‐dual‐doped carbon aerogels from glucose and ovalbumin was developed together with two comonomers S‐(2‐thienyl)‐ l ‐cysteine (TC) and 2‐thienyl carboxaldehyde (TCA) as sulfur precursor .…”

Advanced Biomass‐Derived Electrocatalysts for the Oxygen Reduction Reaction

Recent progress in advanced nanostructures synthesized from biomass resources for the oxygen reduction reaction (ORR) is reviewed. The ORR plays a significant role in the performance of numerous energy-conversion devices, including low-temperature hydrogen and alcohol fuel cells, microbial fuel cells, as well as metal-air batteries. The viability of such fuel cells is strongly related to the cost of the electrodes, especially the cathodic ORR electrocatalyst. Hence, inexpensive and abundant plant and animal biomass have become attractive options to obtain electrocatalysts upon conversion into active carbon. Bioresource selection and processing criteria are discussed in light of their influence on the physicochemical properties of the ORR nanostructures. The resulting electrocatalytic activity and durability are introduced and compared to those from conventional Pt/C-based electrocatalysts. These ORR catalysts are also active for oxygen or hydrogen evolution reactions.

“…Considering the natural abundance, renewability, environmental friendliness, and low cost, biomass has been regarded as a renewable and sustainable carbon precursor for fabricating carbon aerogels. Up to now, several biomass‐derived carbon aerogels have been successfully developed from gelatin,16 winter melon,17 protein,18 bacterial cellulose,19 and raw cotton 20. However, those carbon aerogels show poor compressibility, elasticity, and fatigue resistance owing to the intrinsic random porous architecture and severe volume shrinkage at annealing or carbonization.…”

Lightweight and elastic carbon materials have attracted great interest in pressure sensing and energy storage for wearable devices and electronic skins. Wood is the most abundant renewable resource and offers green and sustainable raw materials for fabricating lightweight carbon materials. Herein, a facile and sustainable strategy is proposed to fabricate a wood-derived elastic carbon aerogel with tracheid-like texture from cellulose nanofibers (CNFs) and lignin. The flexible CNFs entangle and assemble into an interconnected framework, while lignin with high thermal stability and favorable stiffness prevents the framework from severe structural shrinkage during annealing. This strategy leads to an ordered tracheid-like structure and significantly reduces the thermal deformation of the CNFs network, producing a lightweight and elastic carbon aerogel. The wood-derived carbon aerogel exhibits excellent mechanical performance, including high compressibility (up to 95% strain) and fatigue resistance. It also reveals high sensitivity at a wide working pressure range of 0-16.89 kPa and can detect human biosignals accurately. Moreover, the carbon aerogel can be assembled into a flexible and free-standing all-solid-state symmetric supercapacitor that reveals satisfactory electrochemical performance and mechanical flexibility. These features make the wood-derived carbon aerogel highly attractive for pressure sensor and flexible electrode applications.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201910292. important applications in wearable sensors, electronic skins, and flexible energy storage devices. Although carbon aerogels with good mechanical performances can be achieved from nanocarbon unites, their carbon precursors are nonrenewable, and the synthesis process of CNT, graphene, or their aerogels is high-cost and complicated.Considering the natural abundance, renewability, environmental friendliness, and low cost, biomass has been regarded as a renewable and sustainable carbon precursor for fabricating carbon aerogels. Up to now, several biomass-derived carbon aerogels have been successfully developed from gelatin, [16] winter melon, [17] protein, [18] bacterial cellulose, [19] and raw cotton. [20] However, those carbon aerogels show poor compressibility, elasticity, and fatigue resistance owing to the intrinsic random porous architecture and severe volume shrinkage at annealing or carbonization. Wood, as one of the most abundant biomass resources, demonstrates hierarchical tracheid structure that is composed of CNFs and amorphous matrix (lignin and hemicelluloses). [21] Owing to the compact structure (large amounts of additives and various interaction among tracheids or CNFs), natural wood is rigid and the tracheids are hard to be compressed and easily collapsed. Therefore, fabricating compressible and elastic conductive carbon aerogel from original wood tracheids is challenging. To solve this problem, Hu et al. [22] put forward a "top-down" stra...

“…However, the method of simply mixing and calcining the carbon supports and nitrogen sources cannot make full use of the specific surface area of the carbon supports to interact with nitrogen sources and further form more active sites. Moreover, the traditional nitrogen sources, such as melamine and polyaniline, are easily lost in the process of pyrolysis; hence researchers try to use some novel high nitrogen content materials like g‐C 3 N 4 and biological nitrogen sources to increase the number of nitrogen‐doped sites on carbon materials . Based on the above considerations, we synthesized a kind of Fe−N coordination MOFs, and then an in situ synthesis method was designed to incorporate the MOFs into carbon aerogels during the precursor polymerization process to make better use of the porous structure and the large specific surface area of carbon aerogels.…”

A novel composite Fe‐bpdc‐C3N4‐CA catalyst (where bpdc stands for 2,2′‐bipyridine‐3,3′‐dicarboxylic acid and CA stands for carbon aerogel) with a high nitrogen content was synthesized through the in situ encapsulation of nitrogen‐containing metal organic frameworks along with g‐C3N4 into porous CAs. The characteristics of the catalysts calcined at different temperatures were determined by means of TEM, XRD, Raman spectroscopy, XPS, and BET measurements. The results demonstrate the successful doping of N heteroatoms and the effective formation of Fe‐NX active sites. The electrocatalytic properties were investigated by using rotating disk electrode (RDE) and rotating ring disk electrode (RRDE) measurements. The Fe‐bpdc‐C3N4‐CA catalyst calcined at 800 °C exhibits the highest oxygen reduction reaction activity with the initial reduction potential and half‐wave potential reaching 1.09 and 0.96 V, respectively, versus RHE in 0.1 M KOH. It also possesses high stability and follows approximately a complete four‐electron (4e−) reaction pathway, as commercial Pt/C catalysts do.
