Finally, Inal et al 39 investigated the catalytic activity of Microcystis aeruginosa microalgae supported manganese material in the methanolysis reaction of sodium boron hydride, and they calculated the capacitance of the electrodes as 40 F/g by measuring the supercapacitor of this material. In addition, by using this catalyst material, a supercapacitor cell was designed for energy storage.…”

Summary In this study, pomegranate peel (PP) waste was used as an efficient, cost‐effective, and metal‐free catalyst for the methanolysis reaction of sodium borohydride (NaBH4); furthermore, the prepared active material was utilized as a supercapacitor for electricity storage. The effect of several parameters, such as different acid concentrations, burning temperature, and burning times on the catalytic performance of the pomegranate peel catalyst (PP‐H3PO4‐Cat) were examined. Under optimum conditions, the most active catalyst was obtained by burning with 7 M phosphoric acid (H3PO4) solution at 400°C for 45 minutes. The maximum hydrogen generation rate (HGR) obtained from the methanolysis reaction of NaBH4 at 30°C and 60°C was found as 57 200 and 76 228 mL min−1 gcat−1, respectively. The activation energy value for the catalytic methanolysis reaction was calculated as 7.89 kJ mol−1. Furthermore, Fourier transform infrared spectroscopy (FTIR), inductively coupled plasma ‐ optical emission spectrometry (ICP‐OES), X‐ray diffractometer spectroscopy (XRD), Brunauer‐Emmett‐Teller (BET), and scanning electron microscope (SEM) analyses were performed for characterization of the synthesized catalyst. The gravimetric capacitance of the prepared electrode (catalyst material with best results) was calculated as 29 F/g at 0.25 A/g current density. The electrodes made from biomass waste are both cheap and have a good capacity.

Orijinal Bilimsel Makale Bu çalışmada, asetik asit ile muamele edilmiş metal katkılı atık asfalt katalizörü kullanılarak sodyum bor hidrürün metanolizinde hidrojen sentezi gerçekleştirilmiştir. Farklı metal türleri denenerek en verimli metal türü belirlenmesinin ardından farklı oranlarda metal kullanılmış ve en etkin katalizör üretilmiştir. En verimli katalizör, 3M asetik asit ve % 30 Cu ile muamele edilmiş atık asfalt katalizörüdür. Seçilen katalizör varlığında, en yüksek hidrojen verimini elde etmek için farklı katalizör miktarları, farklı sodyum bor hidrür konsantrasyonları ve farklı sıcaklıklar kullanılarak deneyler yapılmış ve sonuçlar yorumlanmıştır. Maksimum hidrojen üretimi verimi 9518,3 mLdk-1g-1 ve katalizörün aktivasyon enerjisi 38,2 kj/mol olarak belirlenmiştir.

“…This can primarily be attributed to its copious sources, affordability, eco-friendliness, and excellent electrochemical performance. [16] However, it is practically challenging to apply a single carbon material in a large-scale commercial supercapacitor with the key requirements (energy density and power density). [17,18] Layered double hydroxides (LDH) have emerged as a highly promising greener material for future research in supercapacitors.…”

Energy density and power density are the two most crucial metrics in advanced electrochemical energy storage (EES) devices. The design of pseudocapacitor materials with good structure and reasonable composition can ensure that the power density can be greatly increased under the condition of little or no reduction in energy density. However, how to reasonably design excellent pseudocapacitor materials is still a huge challenge. Herein, layered double hydroxides containing Ni and Co elements on carbon materials derived from distillers’ grains by hydrothermal synthesis (NiCo‐LDH/JKPC‐2) are grown. The fabricated NiCo‐LDH/JKPC‐2 has exhibited a sea urchin‐like nanostructure that primarily consists of mesoporous and possesses a high specific surface area (303 m2 g−1), which facilitates the formation of larger active sites, thereby increasing the rate of charge transport. The specific capacitance of the NiCo‐LDH/JKPC‐2 reaches a maximum value of 1454 F g−1 at 1 A g−1. When it combines with carbon materials originating from distillers’ grains, the assembled asymmetric supercapacitor electrode exhibits a remarkable energy density (40.86 Wh kg−1 at 775 W kg−1) and superior power density (7750.8 W kg−1 at 21.53 Wh kg−1). Thus, the NiCo‐LDH/JKPC‐2 asymmetric supercapacitor electrode can be considered as a potential candidate in advanced energy storage device systems.
