Enhancing the Oxygen Evolution Performance by Introducing NiO‐Supported Mesoporous Titanium Dioxide

open access: yesChemistryOpen, EarlyView.
Herein, a schematic representation of the synthesis of NiO‐supported mesoporous TiO2 is reported. The process involves self‐assembly of polyvinylpyrrolidone (PVP), Ti(acac)2, nickel salt, and ethanol, followed by solvent evaporation, thermal polymerization, and stepwise calcination under N2 (350 °C) and air (450 °C) to remove PVP and carbon, yielding ...

Water Co‐Adsorption in Ultrathin Films of Ionic Liquids on Pt(111)

open access: yesChemistryOpen, EarlyView.
At 100 K, IL adsorption on D2O precovered Pt(111) partially displaces interfacial water resulting in a water‐IL co‐adsorbed layer. Upon heating to 130 K, IL ions migrate to the metal interface, thereby destabilizing adsorbed water as shown by the ≈10 K reduction in its desorption temperature.
