By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Chalcogens have been presented. According to news reporting out of Jeddah, Saudi Arabia, by NewsRx editors, research stated, "Direct mixing of aqueous dispersions of ultrathin g-C3N4 nanosheets and graphene oxide (GO) under ultrasonication leads to three-dimensional (3D) porous supramolecular architecture. Photoreduction of GO yields conductive porous g-C3N4/rGO hybrid."
Our news journalists obtained a quote from the research from King Abdul-Aziz University, "The resulting 3D architecture possesses high surface area, multilevel porous structure, good electrical conductivity, efficient electron transport network, and fast charge transfer kinetics at g-C3N4/rGO interfaces, which facilitate the diffusion of O-2, electrolyte, and electrons in the porous frameworks during oxygen reduction reaction (ORR). Ultrathin g-C3N4 nanosheet also causes effective electron tunneling through g-C3N4 barrier, leading to rich electrode-electrolyte-gas three-phase boundaries, and shortens the electron diffusion distance from rGO to O-2."
According to the news editors, the research concluded: "As a novel ORR catalyst, such 3D hybrid exhibits remarkable catalytic performance, outperformed other g-C3N4/rGO composites, and exhibits excellent durability."
