We show that the activity of cobalt for the oxygen evolution reaction (OER) can be enhanced by confining it in the interlayer region of birnessite (layered manganese oxide). The cobalt intercalation was verified by employing state-of-the-art characterization techniques such as X-ray diffraction, Raman spectroscopy, and electron microscopy. It is demonstrated that the Co/birnessite electrocataly...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
The usefulness of Pt-based nanomaterials for catalysis can be greatly enhanced by coupling morphology engineering to the strategic presence of a second or even third metal. Here we demonstrate the design and preparation of stellated Ag-Pt bimetallic nanoparticles where significant activity difference between the methanol oxidation reaction (MOR) and the oxygen reduction reaction (ORR) may be re...
Developing efficient platinum-based electrocatalysts with super durability for the oxygen reduction reaction (ORR) is highly desirable to promote large-scale commercialization of fuel cells. Although progress has been made in this aspect, electrochemical kinetics and stability catalysts are still far from requirements practical applications. Herein, PtPdFeCoNi high-entropy alloy (HEA) nanoparti...
Abstract Nitrogen-doped reduced graphene oxide is successfully synthesized and functionalized with hydroxylated copper ions via one-pot microwave-assisted route. The presence of cationic Cu coordinated to the layer fully elucidated through a set experimental characterizations theoretical calculations. Thanks these hydroxyl-coordinated 2+ active sites, proposed material shows good electrocatalyt...
