CrN/Cu composite powders were synthesized by employing a novel two-step technique. Firstly, the Cr2O3+CuO precursors were prepared by the solution combustion synthesis (SCS) method using cupric nitrate, urea, and chromium nitrate as initial materials. Subsequently, the SCS precursors were calcined at 850 °C in NH3 for 6 h, and transformed to CrN/Cu composite powders. The composite powders consi...

The enhanced power density, long term cycling stability, and fast rate of operation, makes supercapacitors as desirable energy storage devices. Though metal oxides play a significant part in systems, Vanadium have piqued the interest electrochemists due to their multi-valency, potential window, unique layer structure, affordability, plentiful availability. pentoxide typically has relatively low...

The paper presents the results of a detailed study process and products combustion during self-propagating high-temperature synthesis (SHS) ZnO zinc oxide powder from mixtures such common reagents as oxidizer nitrate reducing agent (fuel) glycine, well application synthesized highly dispersed submicron nanosized for phenol photocatalytic decomposition under action ultraviolet irradiation. An aq...

High-entropy metal spinel oxide (HEO) is proved to be a promising oxygen evolution reaction (OER) catalyst with high catalytic performance and stability. A short routine synthesis process based on solution combustion was proposed prepare (Co0.25Ni0.25Mn0.25Zn0.25)Fe2O4 HEO in this work. During the process, products were rapidly synthesized melted due high-temperature reaction, then quickly crys...
