The bi-transition-metal interstitial compounds (BTMICs) are promising for water electrolysis. The previous BTMICs are usually composed of irregular particles. Here, this work shows the synthesis of novel 1D CoMoC-based heterojunction nanowires (1D Co/CoMoC) with diameters about 50 nm and a length-to-diameter ratio about 20 for efficient water electrolysis.

Article Synopsis
- The crystalline zirconium tungstate (ZrWO) exhibits catalytic properties particularly suited for liquid-phase selective oxidation of various organic substrates using aqueous hydrogen peroxide as a green oxidant.
- Characterization techniques like N adsorption, PXRD, and IR spectroscopy indicated the presence of Brønsted acidic and basic sites on ZrWO's surface, enhancing its catalytic activity.
- The catalyst effectively facilitates reactions such as epoxidation of alkenes, oxidation of thioethers and alcohols, and regenerates well without losing activity or selectivity.
In the presented work, the effect of friction stir processing admixing the zirconium tungstate ZrWO powder on the microstructure, mechanical and tribological properties of the AA5056 Al-Mg alloy stir zone has been studied. The FSP resulted in obtaining dense composite stir zones where α-ZrWO underwent the following changes: (i) high-temperature transformation into metastable β'-ZrWO and (ii) decomposition into WO and ZrO oxides followed by the formation of intermetallic compounds WAl and ZrA. These precipitates served as reinforcing phases to improve mechanical and tribological characteristics of the obtained fine-grained composites.
