Graphene oxide modified with magnesium hydroxide derived from dolomites for dyes adsorptions and supercapacitor
This research highlights the novelty of using dolomite as an Mg(OH)2 source for synthesizing GO/Mg(OH)2 nanocomposite, a dye adsorbent and supercapacitor material. So far, dolomite has only been conventionally used as fertilizer and building material. By utilizing dolomite as Mg(OH)2 raw materials, this nanocomposite shows high efficiency in removing methylene blue (MB) up to 97 % with adsorption kinetics following a pseudo-second-order model. At an optimal pH of 5, this material can be used repeatedly with satisfactory results. For supercapacitor applications, GO/Mg(OH)2 has a specific capacitance of 117.80 F g−1 at a current density of 0.5 A g−1 and 90 % cyclic capacity retention, making it an excellent candidate in modern energy storage technology.
