Researchers report fundamental discoveries about how water reacts with nanostructured metal oxide surfacesUniversity of WisconsinMadisonNature Communications
Supported metal nanoclusters consisting of several dozen atoms are highly attractive for heterogeneous catalysis with unique catalytic properties. However, the metal nanocluster catalysts face the challenges of thermal sintering and consequent deactivati
In a preliminary section, the interaction of water with metallic surfaces will be reviewed to examine if water selectively reacts with O vacancies of the support or not. 2. Interaction of water with metallic surfaces The behavior of water on metal surfaces was reviewed in 1988 by Heras and ...
Here, we report a highly orientated phase-enabled MOF homojunction with a well-defined junction interface for visible-light-driven CO2 reduction. It is well known that the dynamic feature of supramolecular coordination bonds in MOFs allows metal nanoparticles (NPs) to react with MOFs28,29. Metal ...
For Li-, Na-, and K-air batteries with aprotic electrolytes, oxygen reacts with metal ions on the air electrode, and the discharge product on the air electrode can be metal superoxides or peroxides. The electrode reactions are as follows:(Equation 3)Metal electrode: M ↔ M+ + e−,...
reactants. It is notable that due to the insolubility of N2gas and NO gas, the concentrations of N2and NO are uncertain during the experiments, this parameter cannot be applied in the reduction of N2and NO processes. An example equation is shown in the following for the evaluation of NOx...
the product of ionic mobility (μ) and free carrier concentration (c)19. Ion transport through polymer electrolytes is intimately coupled to the motion of the polymer chain. The activation energy (Ea) was calculated with the Vogel–Tamman–Fulcher (VTF) empirical equation. As shown in Fig.3f...
To sum up, the characterization results obtained after UOR demonstrate that, in these conditions, NiFePB reacts with KOH to generate a Ni(OH)2 phase on the Ni film, which is electrochemically converted to NiOOH at potentials more positive than 1.37 V vs RHE (Supplementary Fig. 19a)31,...
Biocatalytic transformations in living organisms, such as multi-enzyme catalytic cascades, proceed in different cellular membrane-compartmentalized organelles with high efficiency. Nevertheless, it remains challenging to mimicking biocatalytic cascade pr
Using Equation 2, we calculate Sand’s time for experiments performed at 0.2 mA/cm2 to be 1,519 s, or about 25 min, which corresponds well to a local voltage maximum in the high (negative) overpotential regime from data in Figure 3A, denoted with a circle. This signifies the point ...
