PROBLEM TO BE SOLVED: To provide a method for extracting and separating a solvent of a novel metal, capable of efficiently extracting and separating noble metal elements from a hydrochloric acid solution with easy processes and operations.SASAKI YUJI...
A process for the direct hydrogenation of hop resin acids in the absence of a liquid, organic solvent by reacting the hop resin acids with hydrogen in the presence of a noble metal catalyst at a temperature at which the resin acids are sufficiently fluid to allow easy mixing with the catalys...
The well known methods of Job's continuous variations and mole-ratio were used for the determination of the compositions of some metal-N,N-diethyl-N'-benzoyl-thiourea complexes chromatographically using HPTLC-densitometry. A different and a simple application of these two methods makes the determina...
Noble metal-free Ni(OH)2–g-C3N4 composite photocatalyst with enhanced visible-light photocatalytic H2-production activity Ni(OH)2-modified graphitic carbon nitride (Ni(OH)2–g-C3N4) composite photocatalysts were prepared by a simple precipitation method using g-C3N4 as support... J Yu,S Wang,...
From Hydrogenases to Noble Metal–Free Catalytic Nanomaterials for H2 Production and Uptake Interconversion of water and hydrogen in unitized regenerative fuel cells is a promising energy storage framework for smoothing out the temporal fluctuatio... AL Goff,V Artero,B Jousselme,... - 《Science》 ...
This invention relates to a catalytic composite for treating an exhaust gas comprising a first support which is a refractory inorganic oxide having dispersed thereon at least one noble metal component and having dispersed immediately the... MG Henk,Jack C. Summers II - US 被引量: 236发表: 1991...
The transparent conductive layer forming coating liquid of the present invention is characterized in that it comprises, as its main components, a solvent and noble metal microparticles with a mean particle diameter of 1 to 100 nm dispersed in the solvent, and that the above-mentioned solvent ...
Due to the unique “solvent-pair surfactants” enabled indirect interaction, the SPEA method allows for a facile strategy to synthesize functionalized mMOs with tailored pore-wall microenvironments by directly introducing additional components like precursors of other metal oxides and noble metal nanoparticl...
For example, in studies conducted by Nguyen et al., Pd and Pt were extracted from an acidic chloride solution with the organic phase of the ionic liquid Cyphos IL 101 diluted with xylene. The obtained extraction efficiencies of both these metals indicated the quantitative recovery of the tested...
Based on the thermodynamically unstable nature of ultra-fine Te nanowires, they prepared series-based materials, such as noble metals, alloys, telluride, and carbon-based hybrids37–40. For instance, to obtain Pt nanowires37 or PtPdTe alloys38, the ultra-fine Te nanowires were used as ...
