“…The proximate analysis of petroleum coke is shown in Table 1. 10 It is noticed from the table, that the carbon content is 90% and ash content is low. The presence of ash influences the leakage of current and low electrochemical stability so if the ash content is low the electrochemical performance becomes better.…”

The present work is to use petroleum coke as a carbon material for energy storage application. Activated petroleum coke (APC) is prepared using potassium hydroxide as an activation agent. Then the APC is doped with nitrogen and manganese-nitrogen components to enhance the capacitance of the material. The X-ray diffraction result shows the turbo static behavior, which is fully disordered structure. The Fourier transform infrared spectroscopy shows the functional groups present in the prepared sample. Using the cyclic voltametry, the specific capacitances are found to be 3.2, 4.8, and 6.3 F/g for APC, nitrogendoped activated petroleum coke (N-APC), and manganese-and nitrogen-doped activated petroleum coke (Mn/N-APC), respectively. The specific capacitance of charge and discharge are also found to be 3.5, 5.2, and 10.3 F/g, respectively, for the above-prepared materials. The specific capacitance of the fabricated Mn/N-APC electrode was found to be 76.1 F/g. From the experimental results, the energy density and power density was found to be 105 and 131.2 Wh/kg, respectively, for the abovementioned material. It is concluded from the present experiment that Mn/N-APC shows good electrochemical properties. Hence, this can be used as a supercapacitor for energy storage applications.

Bu çalışmada, atık çay çalısından elde edilen düşük maliyetli, bol miktarda bulunan, verimli ve çevre dostu bir biyo-atık, adsorban olarak değerlendirilmiştir. Çevreyi kirleten maddelerin giderimleri için bu çalışmada kullanılan doğal ürün, mevcut pahalı yöntem ve hammaddelerine alternatif olarak sunulmuştur. Eosin Y (EY) sulu çözeltiden adsorpsiyonunda, etkileşim süresi, pH, adsorban miktarı vb. gibi çeşitli parametrelerin etkileri incelenmiş ve optimum deney koşulları ortaya konmuştur. Deneysel sonuçlar ışığında, Langmuir izoterm modelinde, 25°C'da maksimum adsorpsiyon kapasitesi 3,56 mg/g olarak hesaplanmıştır. Veriler ışığında Freundlich modelinin deneysel verilerle daha iyi bir uyum sağladığı tespit edilmiştir. Mevcut araştırmalar ve bildirilen diğer adsorbanlarla karşılaştırıldığında, çay çalısının, sulu çözeltiden EY'nin giderilmesi için düşük maliyetli doğal ürün olması sebebiyle, bir seçenek olarak uygulanabileceği sonucuna varılmıştır.

“…Among the emergent dyes, Congo red (CR) in terms of molecular structure presents a kind of complex azo compound constituting of many carcinogenic aromatic rings, amines, and imines ( Figure 1) [3]. Under appropriate aerobic reactions, these CR molecules are likely to react/combine with functional groups on the surface of other molecular systems in the body, raising potential risks of genetic mutation (GM) [4,5]. Therefore, treatment of persistent and non-degradable CR molecules should be a priority regardless of the huge challenges relating to cost and technologies.…”

Natural graphite, a locally available, eco-friendly, and low-cost carbonaceous source, can be easily transformed into exfoliated graphite (EG) with many surface functional groups via a chemical oxidation route. Combination between EG and magnetic MnFe2O4 is a promising strategy to create a hybrid kind of nanocomposite (EG@MnFe2O4) for the efficient adsorptive removal of Congo red (CR) dye from water. Here, we reported the facile synthesis and characterization of chemical bonds of EG@MnFe2O4 using several techniques such as Fourier-transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS). In particular, the quantity method by Boehm titration was employed to identify the content of functional groups: Carboxylic acid (0.044 mmol/g), phenol (0.032 mmol/g), lactone (0.020 mmol/g), and total base (0.0156 mmol/g) on the surface of EG@MnFe2O4. Through the response surface methodology-optimized models, we found a clear difference in the adsorption capacity between EG-decorated MnFe2O4 (62.0 mg/g) and MnFe2O4 without EG decoration (11.1 mg/g). This result was also interpreted via a proposed mechanism to elucidate the contribution of surface functional groups of EG@MnFe2O4 to adsorption efficiency towards CR dye.
