“…This phenomenon is maybe connected with the relatively lower ionic mobility of EMIMBF 4 and LiPF 6 electrolytes, which have a higher viscosity. Besides, it can be easily found that the Nyquist plots of all supercapacitors are almost vertical lines at the low frequency region, manifesting that the supercapacitors possess a good ion diffusion/migration behavior and typical double-layer charge storage characteristic …”

Supercapacitive behaviors of the porous carbon electrode principally depend on the properties of electrolyte. In this paper, activated hollow porous carbon spheres (AHPCSs) with large specific areas were prepared by the hydrothermal method and subsequent one-step KOH activation treatment. The electrochemical performances and supercapacitive characteristics of the AHPCS supercapacitors were evaluated in 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF4) ionic liquid electrolyte, 1 mol L–1 LiPF6 organic electrolyte, and 6 mol L–1 KOH aqueous electrolyte. It has been found that the supercapacitors with AHPCS electrode have definitely good supercapacitive behaviors in the three electrolytes. Especially, the AHPCS supercapacitor in the EMIMBF4 ionic liquid electrolyte that has a wide operating voltage of 0–3.0 V exhibits an excellent rate performance with capacitance retention of 72.3% from 0.5 to 10 A g–1 and a good cycle performance with a high capacitance retention of 94.2% after 4000 consecutive cycles. Moreover, it obtains a high energy density of 80.5 Wh kg–1 at 750 W kg–1, which transcends most of the currently reported carbon-based supercapacitors. Therefore, the supercapacitors with EMIMBF4 ionic liquid as electrolyte and AHPCSs as active electrode materials show tremendous potential in terms of boosting comprehensively electrochemical performance.

Low‐ and negative‐value (waste) products represent a valuable resource. Its use as a source for the fabrication of high value materials represents a lucrative pathway to increasing sustainability and decreasing the economic cost of various industries. Thermochemical methods for the valorization of biowaste and low‐value natural products are simple and cheap yet sufficiently efficient to deliver significant economic benefits. Plasma‐based methods represent another family of technologies for waste‐to‐value conversion. The nanostructure nucleation and growth in plasmas involve a complex set of physical and chemical processes that occur in bulk plasma and on surfaces. The choice between these two types of technology assumes a complex optimization that takes into account several factors including the cost of precursors; initial outlay and operating cost of equipment; the cost of labor; the cost of production engineering including the research and development efforts for designing the industrial technology, which is typically higher for the plasma‐based systems, and so on. In this article a technology level comparison of thermochemical and plasma‐based techniques for the valorization of raw and waste biomass, where the intent is to use the resulting products for environmental remediation, energy storage, optoelectronics, and biomedical applications, is presented.

Peanut Shell Derived Carbon Combined with Nano Cobalt: An Effective Flame Retardant for Epoxy Resin

et al. 2021

Biomass-derived carbon has been recognised as a green, economic and promising flame retardant (FR) for polymer matrix. In this paper, it is considered that the two-dimensional (2D) structure of carbonised peanut shells (PS) can lead to a physical barrier effect on polymers. The carbonised sample was prepared by the three facile methods, and firstly adopted as flame retardants for epoxy resin. The results of thermal gravimetric analysis (TGA) and cone calorimeter tests indicate that the carbon combined with nano Cobalt provides the most outstanding thermal stability in the current study. With 3 wt.% addition of the FR, both peak heat release rate (pHRR) and peak smoke production rate (PSPR) decrease by 37.9% and 33.3%, correspondingly. The flame retardancy mechanisms of the FR are further explored by XPS and TG-FTIR. The effectiveness of carbonised PS can be mainly attributed to the physical barrier effect derived by PS’s 2D structure and the catalysis effect from Cobalt, which contribute to form a dense char layer.
