A new mechanism of catalyst has been demonstrated in this article. With the interaction between carbon nitride (CN) and encapsulated nickel, the CN in the catalyst has been endowed with new active sites for the adsorption and activation of hydrogen while nickel itself is physically isolated from the contact with reactive molecules. For the selective hydrogenation of acetylene in large amount of ethylene,...
The successful development of Li-O2 battery technology depends on developing a stable and efficient cathode. As an important step toward this goal, for the first time, we report the development of CeO2 nanoparticles modified NiCo2O4 nanowire arrays (NWAs) grown on the carbon textiles as a new carbon-free and binder-free cathode system. In this study, the Li-O2 battery with the CeO2@NiCo2O4 NWAs has...
