“…The FT-IR spectrum of CoTLM exhibits a broader peak at 2000-3400 cm −1 , which can be attributed to its higher hydrophilic and conductive nature. Peaks at 1457, 1592, and 1710 cm −1 are assigned to the ester and carboxylic acid functional groups in cellulose-based polysaccharides 6,[22][23][24][25] . These peaks have been pronounced in 3DFAB, as compared to the RAB, as the result of a series of reactions, which have been shown in Eqs.…”

Two state-of-the-art electrodes were successfully synthesized and used to assemble both symmetric and asymmetric type supercapacitors. 3DFAB was fabricated by direct pyrolysis of green macroalgae in the presence of NaOH. Possible NaOH activation mechanisms are proposed, which explains the formation of oxygen functional groups through quick penetration of OH- and NaOH into the vacancies. To obtain CoTLM, the tile-like architecture of cobalt oxides was introduced to the 3D interconnected functional algal biochar (3DFAB) by a simple one-pot hydrothermal method under mild conditions. For the symmetric supercapacitors, the maximum specific capacitance of RAB, 3DFAB, and CoTLM were 158, 296, and 445 F g−1 at the current density of 1 A g−1. Regarding cobalt-based asymmetric systems, the maximum capacitance for the 3DFAB//CoTLM was 411 F g−1. This asymmetric supercapacitor device also retained 100.9% of its initial capacitance after 4000 cycles at the current density of 4 A g−1. Unbuffered aqueous electrolyte and the unique morphological structure used in this study might catapult forward commercialization of such advanced energy storage devices.

For the symmetric supercapacitors, the maximum specific capacitance of RAB, 3DFAB, and CoTLM were 177 F g− 1, 322 F g− 1, and 529 F g− 1 at a scan rate of 5mVs− 1. Regarding cobalt-based asymmetric systems, the maximum capacitance for the RAB//CoTLM and 3DFAB//CoTLM were ∼300 F g− 1 and 400 F g− 1, respectively. The 3DFAB//CoTLM showed a higher energy density compared with RAB//CoTLM, while the RAB//CoTLM exhibited better cycling performance (99.1% of its initial capacitance after 4 k cycles at the current density of 4 A g 1).

“…Cocurrently, the use of hydrochar as a precursor of composite materials has been an increasing trend in recent years [11]. Hydrochar-based composites made from the physical and chemical addition of metal oxides, zeolites, nano carbons (i.e., carbon nanotubes, carbon nanofibers, graphene, and carbon nitride), and polymers (i.e., polyaniline, polypyrrol, and polythiophene) have been developed for use in various energy conversion and storage systems [12][13][14][15][16]. It is believed that the three-dimensional (3D) structure of modified hydro/biochar uses the interconnected structure as channels for increasing the density of reactants by creating a locally higher pressure [17].…”

This study provides fundamental insight and offers a promising catalytic hydrothermal method to harness cranberry pomace as a potential bioenergy and/or hydrochar source. The physical and chemical properties of Canadian cranberry pomace, supplied by Fruit d’Or Inc., were examined and the optimum operational conditions, in terms of biocrude yield, were obtained by the I-optimal matrix of Design Expert 11. Afterward, cranberry pomace hydrochar (CPH) and zeolite were separately introduced to the hydrothermal liquefaction (HTL) process to investigate the benefits and disadvantages associated with their catalytic activity. CPH was found to be a better host than zeolite to accommodate cellulosic sugars and showed great catalytic performance in producing hydrocarbons. However, high amounts of corrosive amino and aliphatic acids hinder the practical application of CPH as a catalyst. Alternatively, zeolite, as a commercial high surface area catalyst, had a higher activity for deoxygenation of compounds containing carbonyl, carboxyl, and hydroxyl groups than CPH and resulted in higher selectivity of phenols. Due to the low hydrothermal structural stability, coke formation, and narrow pore size distribution, further activations and modifications are needed to improve the catalytic behavior of zeolite. Our results suggest that a composite composed of CPH and zeolite can resolve the abovementioned limitations and help with the development and commercialization of advanced biofuels from cranberry pomace.
