Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

open access: yesCarbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.

Rose Bengal sensitized bilayered photoanode of nano-crystalline TiO–CeO for dye-sensitized solar cell application [PDF]

open access: yes, 2015
There are two traditional ways to read Kant’s claim that every event necessarily has a cause: the weaker every-event some-cause (WCP) and the stronger same-cause same-effect (SCP) causal principles.

Green Chemistry im Chemieunterricht: eine farbstoffsensibilisierte Solarzelle mit sicheren und leicht verfügbaren Materialien

open access: yesCHEMKON, EarlyView.
Farbstoffsensibilisierte Solarzellen (Dye‐sensitized Solar Cells, DSSCs) stellen einen biomimetischen Ansatz zur Umwandlung von Sonnenlicht in elektrische Energie dar, der sich am Funktionsprinzip der Photosynthese orientiert. Trotz ihres seit den frühen 1990er‐Jahren bekannten Konzepts existieren bislang nur wenige experimentelle Zugänge, die zugleich

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,
