(General Physics) the splitting of a spectral line of an atom or molecule into two or more closely spaced components as a result of interaction of the electrons with the magnetic moments of the nuclei. Comparefine structureSee alsoZeeman effect ...
Hydrogen spillover, the migration of activated hydrogen atoms generated by the dissociation of di-hydrogen adsorbed on a metal surface onto a reducible metal oxide support, is a common phenomenon in heterogeneous catalysis22,23,24,25,26. Recently, hydrogen spillover strategy has been taken into ...
advancements in bimSACs, with an emphasis on their pivotal role in hydrogen generation via water splitting. We subsequently delve into advanced experimental methodologies for the elaborate characterization of SACs, elucidate their electronic properties, and discuss their local coordination environment. Overall...
Water splitting is recognized as an environmentally friendly and feasible method to produce hydrogen. However, the high cost, low storage capacity, and poor stability of traditional noble metal-based electrocatalysts have severely limited the industrial application of electrocatalytic water splitting. The...

For several decades, ceria-based catalysts have been the subject of a huge number of studies [24], [25], [26], [27]. Ceria is an oxide which can be reduced by hydrogen into a great variety of cerium suboxides CeO2-x with 0 < x < 0.5 [28]. The temperature-programmed reduction ...
Multiple lines, called multiplets, are often observed for the absorptions of equivalent hydrogen atoms. This phenomenon is called spin-spin splitting. It results from the interaction of the nuclear spin of the hydrogen atoms on an adjacent carbon atoms. In general, sets of hydrogen atoms on non...

A hyperfine splitting at the protons of the hydroxy groups participating in the formation of stable intramolecular hydrogen bonds with the carbonyl oxygen atoms is observed for all radicals. The spin density was calculated by the MO LCAO method in the H眉ckel approximation, taking into ...
But in the presence of a catalyst – in this case cobalt borate – the array of positive charges can withdraw electrons from a water molecule (whose formula can be written as H-O-H), pulling it apart into a positively charged proton – the nucleus of a hydrogen atom – and a neutral...
