Facile Microwave-Assisted Preparation of Hetero-Structured CuCo2S4/CuCo2O4 Nanoparticles Using Organic Agent of Thiourea

Abstract

Ultra-fast one-put microwave assisted strategy is introduced for the synthesis of heterostructured CuCo2S4/CuCo2O4 nanoparticles into a domestic microwave oven with the power of 900 W for 20 min. Thiourea as an organic agent was used as a sulfur source and driving agent to lead the solvent free combustion reaction to obtain this earth-abundant and low-cost mixed chalcogenide/oxide product. The structural and morphological specifications were studied in details using powder x-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and energy dispersion of x-ray spectrometry (EDX). The employed strategy relatively clarifies a new facile, rapid and eco-friendly route to produce heterostructured nanocomposites for different functional purposes.

A Comparative Study of the Influence of Nitrogen Content and Structural Characteristics of NiS/Nitrogen-Doped Carbon Nanocomposites on Capacitive Performances in Alkaline Medium

“…However, the methods described earlier are usually timeconsuming and energy-wasting processes as compared with a microwave reactor. Unlike the conventional heat-transportation mode, the energy required for growing the nanocrystals can be efficiently and homogeneously diffused to the precursors through microwave irradiation [29][30][31]. Therefore, the samples thus obtained are similar to those synthesized by previous methods and can even be completed in a shorter time or at a lower temperature [32,33].…”
