Graphitic Carbon Nitride Doped Copper–Manganese Alloy as High–Performance Electrode Material in Supercapacitor for Energy Storage

Abstract

Here, we report the synthesis of copper–manganese alloy (CuMnO2) using graphitic carbon nitride (gCN) as a novel support material. The successful formation of CuMnO2-gCN was confirmed through spectroscopic, optical, and other characterization techniques. We have applied this catalyst as the energy storage material in the alkaline media and it has shown good catalytic behavior in supercapacitor applications. The CuMnO2-gCN demonstrates outstanding electrocapacitive performance, having high capacitance (817.85 A·g−1) and well-cycling stability (1000 cycles) when used as a working electrode material for supercapacitor applications. For comparison, we have also used the gCN and Cu2O-gCN for supercapacitor applications. This study proposes a simple path for the extensive construction of self-attaining double metal alloy with control size and uniformity in high-performance energy-storing materials.

Thermal, Mechanical and Electrical Properties of Carbon Fiber Fabric and Graphene Reinforced Segmented Polyurethane Composites

“…Carbon materials such as carbon black, carbon nanotube, carbon fiber and graphene have been widely used in multifunctional composite materials with their unique structures and excellent thermal and electrical properties [9][10][11][12][13][14][15]. However, the content of one-dimensional or two-dimensional fillers must be larger than a percolation value to construct an interconnected structure and provide enough conducting paths for electron transport and heat transfer [16,17].…”

Facile Synthesis of Cobalt-Doped Porous Composites with Amorphous Carbon/Zn Shell for High-Performance Microwave Absorption

“…According to the microwave absorbing theory, the microwave absorbing performance is extremely dependent on the dielectric and magnetic loss, as well as the impedance matching of the microwave absorbers [11,12]. Synthesizing composites doped with other materials [13,14], like magnetic metal nanoparticles, by incorporating magnetic elements to precursors, is a recommendable strategy to prepare carbon composites with enhanced microwave absorption performance. Currently, the research of the most commonly used metal organic frameworks (MOFs) in the field of catalysts has provided inspiration for our work.…”

Relationship between morphological and physical properties in nanostructured CuMnO2

“…In the last few decades, there has been a renewed interest in the research on the CuMnO 2 material due to its an exceedingly rich spectrum of potential applications. As a p-type semiconductor [5][6][7], electrode material [8], CuMnO 2 has also been examined regarding photocatalytic activities for hydrogen production or hydrogen storage [9][10][11], oxygen storage [12,13], energy storage [14,15] as well as in the context of multiferroic peculiarities [16]. Remarkably, by the use of a hydrothermal method, nanoparticles with diameters of 50 -100 nm [6], or nanowires [15], can be obtained.…”
