“…Apart from its importance as food, potatoes have extensive uses in industries, mainly due to their starchy nature (Dupuis and Liu 2019). An interesting study conducted by Li et al (2012) used potato starch for in situ fabrication of hybrid carbon nano-fibers and activated carbon used as the substrate to produce eco-friendly and cost-effective carbon nanotubes, which are desirable features for nanotechnology applications in coming times. Potato starch, like its counterparts from other plant sources, consists of amylose and amylopectin.…”

Potatoes are highly consumed food around the world, usually following processing of some kind. Apart from its noteworthy presence in diets, potato starch has a multitude of industrial applications as a food additive and recently in novel domains such as nanotechnology and bioengineering. This review examines the microscopic and spectroscopic methods of characterizing potato starch and compares the different properties. The microscopic techniques such as optical microscopy and Scanning Electron Microscopy (SEM) allow observation of structural elements of potato starch. Differential Scanning Calorimetry (DSC) delves into the thermal behavior of starch in presence of water, while Fourier Transform Infrared (FTIR) spectroscopy and X-Ray Diffraction (XRD) analyze the behavior of various chemical bonds and crystallinity of starch. These characterizations are important from a dietary point of view for patients requiring a low-glycemic diet, as well as in facilitating research into a wider array of industrial applications.

“…In recent years, biomass has attracted significant attention for the preparation of activated carbon [10], due to its renewable nature, low price, minimal environmental impact, and abundant supply [11]. Many different biomass materials have been proposed, including coconut shell [12], cashew shells [13], rice husks [14,15], durian skin [16], sugarcane trash and corn crops [17][18][19], potato starch [20], and banana skin [21] However, these materials typically have low carbon content, high volume-toweight ratio, and high ash content [22]. Accordingly, studies on developing alternative, low-cost carbon sources continue to attract significant attention from researchers.…”

Fine activated carbon (FAC) is prepared from rubber fruit shells (RFS) using two chemical activating agents (ZnCl2 and KOH) and three impregnation ratios (1:3, 1:4, and 1:5). The Brunauer–Emmett–Teller (BET) results show that for a constant impregnation ratio, the ZnCl2 activating agent yields a higher specific surface area than the KOH agent. In particular, for the maximum impregnation ratio of 1:5, the FAC prepared using ZnCl2 has a BET surface area of 456 m2/g, a nitrogen absorption capacity of 150.38 cm3/g, and an average pore size of 3.44 nm. Moreover, the FAC structure consists of 70.1% mesopores and has a carbon content of 80.05 at.%. Overall, the results confirm that RFS, activated using an appropriate quantity of ZnCl2, provides a cheap, abundant, and highly promising precursor material for the preparation of activated carbon with high carbon content and good adsorption properties

“…Based on their specific charge storage mechanism, supercapacitors can be classified into two different categories: electrochemical double layer capacitors (EDLCs) and pseudocapacitors. Generally, pseudocapacitors exhibit significantly higher capacitance and energy density than EDLCs ,. Among the wide range of pseudocapacitance materials investigated, Ni(OH) 2 is one of the most promising candidate as electrode material, owing to its cost effectiveness, high redox activity, and large theoretical capacity (2082 F g −1 ) during the charge/discharge process .…”

Two‐Step Deposition/Reduction Synthesis of Porous Lamellar β‐Ni(OH)₂/Reduced Graphene Oxide Composites with Large Capacitance for Supercapacitors

Ni(OH)2/RGO composite are synthesized though a facile two‐step method, in which the Ni(OH)2 deposition and GO reduction processes take place separately. The present methods promote the deposition of more Ni(OH)2 and full utilization of RGO, owing to the high reactivity, good solubility, and dispersity of GO. Moreover, the utilization of additives is avoided. The Ni(OH)2/RGO synthesized by using the two‐step method shows a uniform porous lamellar structure with a high specific surface area. When employed as a supercapacitor electrode material, the Ni(OH)2/RGO composite exhibits a high specific capacitance of 2877 F g−1, long cycle life with capacitance retention of 86.5 % after 4000 cycles, and high energy density of 120.9 Wh kg−1 at a power density of 0.14 kW kg−1. The Ni(OH)2/RGO composite prepared by using the two‐step method in this work shows 11.8–85.1 % higher specific capacitances than composites fabricated by using the other method. The excellent performances and the facile synthesis method highlight the promising potential of the present Ni(OH)2/RGO composite in supercapacitor applications.
