Special Issue Information

Dear Colleagues,

In recent years, materials-based research work has been attracting the global research community due to its unprecedented role in various parts of device fabrications. Among them, electrochemical methods such as, supercaps, dye-sensitized solar cells, batteries, water splitting, and so on are highly imminent in terms of meeting the future globe energy requirements. Innovation of novel material for electrochemical systems is highly crucial to develop capable components of future energy devices, including storage and production, to improve the currently used, inept devices.

In the last couple of decades, nanomaterials and 1- and 2-dimensional materials have served as gifted materials for various applications, including energy, opto-electronics, bioelectronics, sensors, and biological applications. Recently, nanocomposites, polymer-mixed nanocomposites, and metal organic frameworks have ruled the materialist world due to their unbelievable performance in various electrochemical devices. Hence, this Special Issue is especially focused on publishing novel materials design and characterization for future electrochemical systems. Further, we have planned to extend its scope towards novel characterization techniques to analyze the materials’ capability for device fabrications.

CoO/Co3O4 nanoparticles (NPs) were synthesized by using a fresh egg white-assisted combustion method which acts as a new approach for green synthesis of this composite. This method was carried out by the direct heat of cobalt precursor with egg white at low temperature for very short period. In fact, this route is a novel, cheap and appropriate technique yielding nanoparticle-based materials. CoO/Co3O4 nanoparticles were characterized by examining the structure and identifying the elements and determining the morphology via XRD, FTIR, SEM, EDS and TEM techniques. The sample magnetic observations were measured through the use of a vibrating sample magnetometer (VSM). The results of XRD, EDS, SEM and TEM confirmed the positive synthesis of the cubic CoO/Co3O4 NPs with sponge crystals which proceed. For the as synthesized composite, 57.75 m2/g, 0.0148 cc/g and 10.31 nm were identified to be the SBET, Vp and ȓ, respectively. The cobalt oxide particles in their nature were polycrystalline, and the crystallite sizes varied from 10 to 20 nm. The magnetic measurement showed that the prepared nanocomposite displays room temperature ferromagnetism with an optimum value, 3.45 emu/g, of saturation magnetization. Full article
