Urchin-like hierarchical ruthenium cobalt oxide nanosheets on TiCT MXene as a binder-free bifunctional electrode for overall water splitting and supercapacitors.

Synthesizing efficient electrode materials for water splitting and supercapacitors is essential for developing clean electrochemical energy conversion/storage devices. In the present work, we report the construction of a ruthenium cobalt oxide (RuCoO)/TiCT MXene hybrid by electrophoretic deposition of TiCT MXene on nickel foam (NF) followed by RuCoO nanostructure growth through an electrodeposition process. Owing to the strong interactions between RuCoO and TiCT sheets, which are verified by density functional theory (DFT)-based simulations, RuCoO/TiCT MXene@NF can serve as a bifunctional electrode for both water splitting and supercapacitor applications.

Three-dimensional hybrid of iron-titanium mixed oxide/nitrogen-doped graphene on Ni foam as a superior electrocatalyst for oxygen evolution reaction.

Growing demands for clean and renewable energy technologies have sparked broad research on the development of highly efficient and stable non-noble metal electrocatalysts for oxygen evolution reaction (OER). In this regard, in the present work a three-dimensional FeTiO/nitrogen-doped graphene (denoted as 3D FTO/NG) hybrid electrocatalyst was synthesized via a facile in-situ process using a hydrothermal method. Structural characterization of the prepared nanocomposite is performed by various techniques e.
