High-resolution IR spectroscopy reveals new insights into hydrogen bonding in hydrogen sulfide
Far-infrared spectrum of H2S-H2S at T = 0.37 K calculated using ab initio intermolecular potentials and dipole functions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-53444-6 At first glance, water and the foul-smelling molecule hydrogen sulfide don’t seem to have much in common. However, if you invest a little energy, some differences will disappear. At first glance, the smell of soft drink…

Schottky junction catalyst promotes hydrogen production by non-precious metals in water electrolysis
By KeAi Communications Co. The space charge region generated by the dual modulation induced a local “OH and H+ rich” environment, selectively promoting the OER and HER kinetic behaviors. Credit: Guangping Yang, Sining Yun. Electrically driven water electrolysis has attracted attention as an environmentally friendly method for hydrogen production, as high-purity hydrogen is essential to resolving the energy crisis. However,…
