The surface properties of MOs are mainly governed by the density of oxygen particles and also the ionic nature of the metal-oxygen bond. Moreover, the large surface area of MOs enables the analyte to effectively interact. The surface oxygen introduces different properties to MOs such as atomic ...
Anodic oxygen evolution reaction (OER) is recognized as kinetic bottleneck in water electrolysis. Transition metal sites with high valence states can accelerate the reaction kinetics to offer highly intrinsic activity, but suffer from thermodynamic formation barrier. Here, we show subtle engineering of h...
20. It is reasonable to conjecture that diffusion along metal/ceramic interfaces will be comparable to that along other internal interfaces (e.g., GBs in metals). Yet, metal–oxygen bonds (in
The alkali metals react readily with atmospheric oxygen and water vapour. (Lithium also reacts withnitrogen.) They react vigorously, and often violently, with water to releasehydrogenand form strong caustic solutions. Most common nonmetallic substances such ashalogens,halogenacids,sulfur, andphosphorus...
1–13 Since a great majority of these structures are anionic, and thus salts with obligatory cations, and constituted primarily of early-transition-metal (d-block) elements in their highest oxidation states, the name early-transition-metal-oxygen-anion clusters is generally viewed as appropriate. ...
Luxurious Dream House Looks Like A James Bond-Inspired Villa Dream houses are all over LA and its surroundings. But I bet you haven’t seen the Desert House designed by super-organic architect Kendrick Bangs Kellogg in Joshua Tree, located in Californias’ Mojave Desert is a fusion of what ...
Niobium was produced directly from Nb2O5 using solid oxygen-ion membrane(SOM).In molten flux CaCl2 system,electrolysis voltage is 3.2 V,Nb2O5 pellets preformed and sintered at 1 200 ℃ for 4 h and liquid metal saturated with carbon loaded in zirconia tube act as the cathode and anode,res...
The effect of polarity of a covalent bond is magnified in the case of a hydrogen atom bonded to an atom of either fluorine, oxygen, or nitrogen. In simple molecules, the distortion of the electron cloud is large, causing the hydrogen atoms to be slightly positively charged. For instance, ...
fabricated a new class of oxygen vacancy-enriched CeO2 catalyst with the stabilization of the crucial intermediate of *NO via inserting into vacant sites, which was conducive to the subsequent C–N coupling process rather than protonation [9]. Moreover, Zhang’s group reported a novel Mott–...
