Ag2Se/SnTe nanorod as potential candidate for energy conversion system developed via hydrothermal route

The synthesis of CaCO3/Cu2O/GO nanocomposites was developed by sol-gel auto-combustion method. The analysis of structure was completed on X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and environmental scanning electron microscopy (ESEM). The XRD spectra of the nanocomposites matched the crystal structure of CaCO3/Cu2O. The average crystal size was 20 nm for Cu2O and 25 nm for CaCO3 nanoparticles. FTIR data showed the absorption bands of Cu2O and GO. Raman spectroscopy data confirmed the formation of GO sheets. ESEM micrographs displayed spherical nanoparticles dispersed in GO sheets. X-ray photoelectron spectroscopy showed the peaks of Cu 2p, O 1s, C 1s, Cu 3s, and Ca 2p. The spectra of optical absorption revealed an absorption band of around 450 nm. The calcium content increase led to a decrease in the optical energy gap from 2.14 to 1.5 eV. The production of hydrogen from NaBH4 across the methanolysis reaction was accelerated by the CaCO3/Cu2O/GO nanocomposites. Therefore, these nanocomposites are superior in catalytic hydrogen production systems.

Energy‐saving strategies and programs have been developed by the appropriate organizations in response to rising concerns about the pollution created by fossil fuels in the environment. Compared to conventional batteries, supercapacitors have several advantages than other, including faster charge and discharge times, higher power density, a longer cycle life, and fever negative effects on the environment. Researchers explored perovskite as a novel class of eco‐friendly electrodes for energy conversion devices. In this study, we developed ZnMnO3 via a sol gel route for supercapacitor application. The phases, structure, valance, morphology and surface of the material are determined by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and Brunauer Emmett Teller (BET), respectively. The electrochemical behavior manifested that the fabricated perovskite exhibited high capacitive efficiency of 889 F g−1 at 1 A g−1. The GCD stability test displays the highest capacitive retention of 97 % after 5000 cycles and shows prolong the stability of 50 h. Our findings suggest that the perovskite exhibited the fascinating feature for supercapacitor application to replace the other polluted source of energy.
