The C 1sXPS peak of the NiCuCr/C (Supplementary Fig.8) can be deconvoluted into three peaks at 284.8, 286.1, and 289.5 eV, assigned to the C−C, C−O, and C=O bond, respectively. The coordination environments of NiCuCr/C were further characterized by X-ray absorption fine st...
Besides, the results show that the biaxial strain is an effective tool for adjusting the energy gap where the indirect energy gap under the strain effects ranged within a range of 0.33/0.34 eV at −8% to 0.361/0.464 eV at 6%. At −8% compressive strain, the interfacial charge transfer...
In proton-bearing ionic solids, the proton is tightly localized to a host, or “donor” species and creates a hydrogen bond between the donor and an acceptor species. Both donor and acceptor are often oxygen ions. Unlike other ions, a proton does not have its own electron cloud, so it i...
In response to the pressing need for sustainable and greener energy alternatives, this study investigates into the exploration of hydrogen energy as a promising solution. The purpose of this study is to identify the common challenges and potential solutions in hydrogen energy transition and to validate...
4a), the ground electronic state is V+(5D) which displays a M+–OH2 bond energy of 1.86 eV, which is consistent with the previous studies by Armentrout and colleagues55. The adsorption products (I1) comply with the spin conservation for triplet and quintet potential energy surfaces (...
Metal Fluorides Form Strong Hydrogen Bonds and Halogen Bonds: Measuring Interaction Enthalpies and Entropies in Solution The organometallic compound trans-(tetrafluoropyrid-2-yl)bis(triethylphosphine)-fluoronickel(II) (NiF) is shown to serve as a strong hydrogen bond and halo... S Libri,NA Jasim...
Hydrogen, as a clean energy carrier, is of great potential to be an alternative fuel in the future. Proton exchange membrane (PEM) water electrolysis is ha
A method of separating isotopes of hydrogen which comprises subjecting a mixture of methane and isotopes of hydrogen in a methane to hydrogen mole ratio from about 1000:1 to about 1:10 to a glow electrical discharge from about 10.sup.-3 to about 50eV per hydrogen bond at a temperature fr...
2021, International Journal of Hydrogen Energy Citation Excerpt : Zr-and Hf-MOF-525 hydrogen-binding energies are 0.04–0.15 eV/H2 and 0.06–016 eV/H2. The Zr and Hf-MOF-525 had high dipole moments, which allowed them to trap molecules of hydrogen on their surface [82]. The examination ...
(ii) High energy inci- dent neutron beam: since the collective excitations typically travel at velocities of the order of few thousands of m/s in liquids, the use of high energy (~10–100 meV) thermal neutrons is mandatory. Satisfying both conditions is extremely demanding at experimental ...
