Abstract Development of sustainable electrochemical energy storage devices faces great challenge in exploring highly efficient and low cost electrode materials. Biomass waste derived carbonaceous materials can be used as an alternative to expensive metals in supercapacitor. However, their application limited by low performance. In this study, the combination use of persimmon waste derived carbon and transition metal nitride demonstrated strong potential for supercapacitor application. Persimmon based carbonaceous gel decorated with bimetallic-nitride (N-NiCo/PC) was firstly synthesized through a green hydrothermal method. Electrochemical properties of N-NiCo/PC as electrode in 6 M KOH electrolyte solution were evaluated by using cyclic voltammetry (CV) and charge-discharge measurements. The N-NiCo/PC exhibited 895.5 F/g specific capacitance at 1 A/g current density and maintained 91.5% capacitance retention after 900 cycles. Hence, the bimetallic nitride-based-composite catalyst is a potentially suitable material for high-performance energy storage devices. In addition, this work demonstrated a promising pathway for transforming environmental waste into sustainable energy conversion materials.

Electric field enhanced approach has been used to synthesize different copper hydroxide morphologies as high-performance supercapacitors electrode materials. Employing this efficient, simple and low cost method, various shapes such as rod, flower and cube with an average grain size of 30[Formula: see text]nm to 1[Formula: see text][Formula: see text]m were obtained on the copper substrate. The results revealed that applied electric field considerably accelerates the formation time of nanostructures from several days to close to 1[Formula: see text]min, where some of the desired nanostructures were obtained even in 1[Formula: see text]s. The electrochemical properties of different morphologies were compared using cyclic voltammograms and charge/discharge tests and electrochemical impedance spectroscopy. The obtained results demonstrated that the two types of fabricated structures showed high maximum areal and specific capacitance of 42[Formula: see text]mF/cm2 and 178[Formula: see text]F/g at scan rate of 20[Formula: see text]mVs[Formula: see text], respectively, which make them excellent and promising electrode materials for supercapacitors.
