Water photoelectrolysis has the potential to produce renewable hydrogen fuel, therefore addressing intermittent nature of sunlight. Herein, a monolithic, photovoltaic (PV)-assisted water electrolysis device minimal engineering and low (in μg range) noble-metal-free catalysts loading is presented for unassisted splitting in alkaline media. An efficient double perovskite cobaltite catalyst, originally developed high-temperature proton-conducting ceramic electrolyzers, possesses high activity...
A galvanic deposition method for the in-situ formation of Pt nanoparticles (NPs) on top and inner surfaces high-aspect-ratio black TiO
We suggest ways to control the size of exsolved particles and create regions high particle density within materials.
There is a growing need to control and tune nanoparticles (NPs) increase their stability effectiveness, especially for photo- electrochemical energy conversion applications. Exsolved particles are well anchored can be re-shaped without changing initial location structural arrangement. However, this usually involves lengthy treatments use of toxic gases. Here, the galvanic replacement/deposition method used, which simpler, safer, leads wealth new hybrid nanostructures with higher degree...
Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically themselves, these particles allow lower energy photons in wide band gap Here, we present A-site excess SrTiO3 thin films, doped with Ni, where through subsequent exsolution process created well-socketed Ni surface SrTiO3. These were galvanically replaced by Au, resulting Au variable size on surface, depending galvanic replacement time....

The Cover Feature shows the spontaneous galvanic deposition of metallic Pt nanoparticles on top, but also inner TiO2 nanotube surfaces. High-aspect-ratio and heavily reduced serves as sacrificial template during this electroless deposition. A high-performing stable hydrogen evolution cathode in acidic media is demonstrated prepared via minimal engineering low noble metal loadings. More information can be found Full Paper by A.
