(Nanowerk News) Researchers from the RESOLV Cluster of Excellence at Ruhr-Universität Bochum (RUB) have used current and voltage measurements on individual nanoparticles to determine that the capacitively stored charge at platinum interfaces can be significantly higher than previously assumed. They attribute this to a special arrangement and bonding of water molecules.
To this end, the international team led by Professor Kristina Tschulik, whose ideas were awarded an “ERC Starting Grant” by the European Research Council in 2020, cooperated with partners from France and Israel.
The authors describe their findings in the journal Angewandte Chemie International Edition (“Unexpectedly high capacitance of the metal nanoparticle/water interface: Molecular-level insights into the electrical double layer”).
Although interfaces between metals and water are the…
