The δ+hydrogen of one molecule is strongly attracted to the lone pair of electrons on the oxygen of other molecules. It is not a covalent bond, but the attraction is significantly stronger than a typical dipole–dipole interaction. Hydrogen bonds have about a 1/10th of thestrengthof an aver...
The variation of bonding as function of water molecule content can be seen in Fig. 2 that shows side views of the equilibrium structures of MSA.(H2O)n,(n=1−5) together with the bond. The H2O molecules form two H-bonds (donor and acceptor). For n=1and2(Fig. 2a and b), only ...
The local structure of liquid water as a function of temperature is a source of intense research. This structure is intimately linked to the dynamics of water molecules, which can be measured using Raman and infrared spectroscopies. The assignment of spectral peaks depends on whether they are coll...
However, hydrogen solubility in brine is much less than that of CO2because hydrogen occupies the spaces available between the water molecules during thedissolution processand makes only weakVan der Waals forces. Dipole CO2can make stronghydrogen bondswith hydrogen from its negative atoms. Therefore, ...
Hydrogen is produced by water electrolysis, steam methane reforming, methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems, transportation, hydrocarbon and ammonia production, and metallugical ...
and NMR.90The first hydration layer consists of chemisorbed water, which dissociates to passivate dangling bonds at the solid surface. At moderate humidities, the first layer of physisorbed water forms with rigid, ice-like structure, followed by subsequent physisorbed layers with liquid-like structu...

Therefore, developing non-Pt based earth-abundant materials with a desirable efficiency and ideal longevity as a catalyst for both ORR and HER is of great importance, and has potential practical values for water splitting, metal–air batteries, fuel cells, and other renewable energy devices [5,7...
Understanding the process of PEM water electrolysis Our Proton Exchange Membrane (PEM), simply explained, splits water into its molecules hydrogen and oxygen using an electric current. The PEM membrane serves as barrier between the two electrodes and allows the protons to pass through while prevent...
