This study highlights the feasibility to scale-up photoelectrochemical water splitting TW level using Pt nanoparticles as hydrogen evolution catalyst.
Herein we present surface sensitive operando XAS L-edge measurements on IrOx/RuO2 thin films as well mass-selected RuOx and Ru nanoparticles. We observed shifts of the white line peak toward higher energies with applied electrochemical potential. Apart from case metallic nanoparticles, potential dependencies were purely core-level caused by a change in oxidation state, which indicates no structural changes. These findings can be explained different binding oxygenated species IrOx RuOx....
Nanoparticle engineering for catalytic applications requires both a synthesis technique the production of well-defined nanoparticles and measurements their performance. In this paper, we present new approach to rationally highly active Ni–Mo–S nanoparticle catalysts hydrodesulfurization (HDS), i.e., removal sulfur from fossil fuels. are synthesized by sputtering Mo75Ni25 metal target in reactive atmosphere Ar H2S followed gas aggregation sputtered material into nanoparticles. The filtered...
Mass distribution, morphology and chemical composition critically affect the catalytic properties of Pt<sub>x</sub>Y nanoparticles.
Tightened restrictions call for cleaner transportation fuels to minimize environmental and societal problems caused by the presence of sulfur in fuels. This emphasizes need new better catalysts field hydrodesulfurization (HDS), which aims at removing refractory from different petroleum streams mostly found form alkyl-substituted dibenzothiophenes (β-DBTs). In this work we demonstrate how a setup dedicated testing minute amounts (nanogram) well-defined catalytic systems μ-reactors can be used...
Recent years has seen enormous and impressive progress in the search for non-precious hydrogen evolution reaction (HER) catalysts both electrolysis photoelectrochemical water splitting (PEC) with molybdenum sulfide– cobalt phosphide families of HER showing great potential [1]. Despite progress, no catalyst which matches platinum performance yet been found. To a large degree, hunt is motived by notion that physical scarcity high price precludes it from usage on terawatt scale. Using numerical...

We have recently developed a unique vacuum inlet system, which couples mass spectrometer to an electrochemical experiment like conventional DEMS/OLEMS system – but with unprecedented combination of quantitative and ultrasensitive product detection sub-second time resolution. [1] Using this one-of-a-kind tool, we experimentally map out the behavior Cu-based CO reduction. In particular, study transient overproduction methane. find that very pronounced, methane (compared ethylene) is result...
