Special Issue Information

Dear Colleagues,

Until today, inorganic nanomaterials for energy conversion and catalysis have become increasingly significant in academic research and industrial applications compared to before, such as in air purification, wastewater treatment, bacterial disinfection, and medical science. This is primarily due to unique properties such as their nanoporosity, optical absorption, intense crystalline phases, high specific surface areas, nanomorphology, and high oxidation. Hence, they play a vital role in the successful design of composite catalysts with enhanced efficiency and selectivity and a steady catalytic activity.

This Special Issue aims to track the most recent advances in inorganic nanomaterials in energy conversion and catalysis applications by hosting a mix of original research articles and comprehensive reviews.

Abstract: Growing demands for regenerative energy and electric automotive applications in recent decades. Supercapacitor device has more applications in consumer alternative electronic products due to their excellent energy density, rapid charge/discharge time, and safety. The CuFe2O4 incorporated three-dimensional graphene oxide (3DGS) nanocomposites have been prepared by an ultrasonication process. The synthesized nanocomposites were studied by different characterization studies such as X-ray diffraction, Transmission electron microscopy, Scanning electron microscopy, and X-ray photoelectron spectroscopy. The electrochemical studies were carried out by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) measurements. As prepared 3DGS/CuFe2O4 nanocomposites have exhibited an excellent surface area, high energy storage with appreciable durability also excellent electrocatalysis properties. In addition, the 3DGS has enhanced conductivity, decreased agglomeration, and interfacial charge transportation in the nanocomposites. A supercapacitor with 3DGS/CuFe2O4 coated nickel foam (NF) electrodes exhibits an excellent specific capacitance of 488.98 Fg-1, a higher current density, as well as a higher power density. After 5000 cycles of charge-discharge in a 2.0 M KOH aqueous electrolyte solution, the 3DGS/CuFe2O4/NF electrodes exhibit an outstanding cyclic stability of roughly 95% at 10 Ag-1. As a result, intimates that the prepared nanocomposites could have the potential for energy storage applications. Moreover, the 3DGS/CuFe2O4 electrode exhibited an excellent electrochemical detection of chloramphenicol with a detection limit of 0.5 µM, linear range of 5-400 µM, and electrode sensitivity of 3.7478 µA µM-1 cm-2.

Title: Synthesis of -SO3H functionalized g-C3N4/BiOI heterojunctions for photo(electro)catalytic applications

Abstract: We synthesized a heterojunction photocatalyst combining sulfonic acid-modified graphitic carbon nitride (g-C3N4–SO3H) and bismuth oxyiodide (BiOI). The g-C3N4–SO3H and BiOI were prepared via wet-impregnation and hydrothermal methods, respectively. We characterized the BiOI/g-C3N4-SO3H using various spectroscopic and microscopic techniques. This photocatalyst demonstrates potential for photocatalytic wastewater treatment and photoelectrochemical water oxidation. Furthermore, we employed electrochemical Mott-Schottky measurements to determine the detailed band energy potentials. The results validate the BiOI/g-C3N4-SO3H heterojunction as a promising catalyst for energy and environmental remediation applications.
