Abstract The deposition of preformed nanocluster beams onto suitable supports represents a new paradigm for the precise preparation heterogeneous catalysts. performance materials must be validated in model catalytic reactions. It is shown that gold/copper (Au/Cu) nanoalloy clusters (nanoparticles) variable composition, created by sputtering and gas phase condensation before magnesium oxide powders, are highly active reduction 4‐nitrophenol solution at room temperature. Au/Cu bimetallic offer...
We report the fabrication and electrochemical study of edge-abundant transition metal dichalcogenide (TMD) nanocone arrays. Time-dependent etching by sequential use isotropic O2 anisotropic SF6/C4F8 plasmas on nanosphere monolayer-modified TMD crystals results in very high coverage array structures with tunable aspect ratios interspacings. Electrochemical characterization these arrays via hydrogen evolution reaction (HER), using a low proton concentration electrolyte (2 mM HClO4, 0.1 M...
The activity of transition metal sulfides for the hydrogen evolution reaction (HER) can be increased by sulfur-enrichment active metal-sulfide sites. In this report, we investigate electrochemical sulfidation atmospherically aged WS2 nanoarrays with respect to enhancing HER activity. contrast MoS2, it is found that diminishes Electrochemical and XPS experiments suggest involvement insoluble tungsten oxides in altered electron transfer properties. This demonstrates strong dependence...
Cluster beam deposition is a solvent-free method to prepare films of nanoparticles, one obvious application being heterogeneous catalysis. To address the problem low cluster rates, novel source, “Matrix Assembly Source” was invented recently. Following proof principle studies, here, we demonstrate further scale-up by 2 orders magnitude, equivalent reaching production ∼10 mg clusters (Au100) per hour. This allows preparation cluster-decorated powder catalysts at gram scale, comfortably...
Application of revolve sphere levelling (RSL) as a practical and effective image processing tool for enhancing scanning tunnelling microscopy (STM) images graphene atomic lattices is presented. Low-cost, ambient, non-invasive STM methods overcome limitations traditional imaging like transmission electron (STEM) (TEM) that can introduce or alter defects in graphene. Utilizing high-quality synthesized via Paragraf's patented Metal-Organic Chemical Vapor Deposition (MOCVD) method, RSL, which...
The anodic behavior of silver was investigated under controlled diffusion conditions in alkaline solutions. Experiments were carried out linear flow control and also using a rotating disk electrode. electrical optical properties the oxide films measured. On basis these results, we point difficulties involved with surface roughness interpreting layer kinetics. Finally, suggest mechanism for film formation stirred conditions, involving dissolution followed by precipitation, rate‐controlling...
