Abstract Molybdenum disulfide (MoS 2) nanostructures are promising catalysts for proton‐exchange‐membrane (PEM) electrolyzers to replace expensive noble metals. Their large‐scale application demands high activity the hydrogen evolution reaction (HER) as well robust durability. Doping is commonly applied enhance HER of MoS 2 ‐based nanocatalysts, but effect dopants on electrochemical and structural stability yet be discussed. Herein, operando measurements materials down nanometric scale...
Sapphire is a technologically highly relevant material, but it poses many challenges when performing epitaxial thin-film deposition. We have identified and applied the conditions for adsorption-controlled homoepitaxial growth of c-plane sapphire. The films thus grown are atomically smooth, controlled termination, outstanding crystallinity. Their chemical purity exceeds that substrates. exhibit exceptional optical properties, such as single-crystal-like bandgap low density F+ centers.
Active and reliable electrocatalysts are fundamental to renewable energy technologies. [1] PdCoO 2 has recently been recognized as a promising catalyst for the hydrogen evolution reaction (HER) in acidic media. [2] This study unveils activation mechanism of , highlighting two key processes: leaching Co atoms from structure formation palladium hydride (PdH x ) nanoparticles. The former process is studied by operando measurement dissolution found be kinetically related HER. Scanning electron...
MoS2 nanostructures are promising catalysts for proton-exchange-membrane (PEM) electrolyzers to replace expensive noble metals. Their broadscale application demands high activity the hydrogen evolution reaction (HER) as well good durability. Doping in is commonly applied enhance HER of MoS2-based nanocatalysts, but effect dopants electrochemical and structural stability yet be discussed. Herein, we correlate operando measurements materials down nanometric scale by identical location electron...
