Reductive Immobilization of Hexavalent Chromium by Polysulfide-Reduced Lepidocrocite
, 2019 The anoxic reduction of lepidocrocite by polysulfide was studied under alkaline conditions (pH 9.5), and the reducing capacity of the resultant reduced lepidocrocite (RL) for hexavalent chromium (Cr(VI)) reduction was examined in the pH range from 6 to ...

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.
