“…[364] In situ detection of the formation of syngas through the optical read-out of Cu reduction has been applied by Omata et al for HTS of catalysts for oxidative methane reforming under pressure. [365] Uniformly sized, multimetallic catalyst nanoparticles deposited onto different substrates (for example, g-Al 2 O 3, CeO 2 , TiO 2 , SiO 2 , or Y-ZrO 2 ) can be prepared by highthroughput through pulsed laser ablation (HT-PLA). The method was developed by Senkan et al, and its use was demonstrated in a search for catalysts for the selective oxidation of propylene.…”

There is increasing acceptance of high-throughput technologies for the discovery, development, and optimization of materials and catalysts in industry. Over the years, the relative synchronous development of technologies for parallel synthesis and characterization has been accompanied by developments in associated software and information technologies. This Review aims to provide a comprehensive overview on the state of the art of the field by selected examples. Technologies developed to aid research on complex materials are covered as well as databases, design of experiment, data-mining technologies, modeling approaches, and evolutionary strategies for development. Different methods for parallel synthesis provide single sample libraries, gradient libraries for electronic or optical materials, similar to polymers and catalysts, and products produced through formulation strategies. Many examples illustrate the variety of isolated solutions and document the barely recognized variety of new methods for the synthesis and analysis of almost any material. The Review ends with a summary of success stories and statements on still-present problems and future tasks.

A high-throughput screening (HTS) reactor for high-pressure oxidative reforming of methane in a direct reaction route was developed. With a combination of catalyst preparation by a split-and-pool method and HTS, Ni-K/alpha-Al(2)O(3) catalyst was found to show high activity under 1 MPa at 650 degrees C with high selectivity even when O(2) conversion is less than 100%. The HTS reactor required a new simple syngas detector operable under high pressure because the number of parallel reactor is limited when equipped with the conventional detection system. The complexity of the pressure reducing unit is the main reason of the limitation. Reduction of metal oxide accompanied with the color change was applied to the detection system. Copper oxide was supported on the filter disk made of alumina, and the filter was placed underneath the catalyst bed. After the methane was oxidatively reformed under 1 MPa at 650 degrees C, color change of spots from dark brown to light brown was observed just under the catalyst which produced hydrogen. Color change of the disk can be used to detect hydrogen formation from the reforming catalyst under pressure.

Hochdurchsatztechniken zur Entdeckung, Entwicklung und Optimierung von Materialien und Katalysatoren gewinnen zunehmend an Akzeptanz in der Industrie. Über die Jahre ist eine relative, synchron verlaufende Entwicklung von Techniken zur parallelisierten Herstellung und Charakterisierung mit dazugehöriger Software und Informationstechnologien zu verzeichnen. Im vorliegenden Aufsatz wird versucht, einen umfassenden Überblick über den Stand der Technik an ausgewählten Beispielen zu vermitteln. Datenbanken, “Design of Experiment”, Data‐Mining‐Techniken, Modellierungstechniken und Entwicklung evolutionärer Strategien werden ebenso angesprochen wie die vielen komplexen Materialien, für deren Erforschung bereits geeignete Techniken entwickelt wurden. Unterschiedlichste Methoden zur parallelisierten Synthese führen zu Einzelsubstanz‐ oder Gradientenbibliotheken für elektronische und optische Materialien ebenso wie für Polymere und Katalysatoren oder anhand von Formulierungsstrategien erzeugten Produkten. Viele Beispiele illustrieren die unterschiedlichsten Insellösungen und dokumentieren eine bisher kaum wahrgenommene Vielfalt an neuen Verfahren für Synthese und Analyse nahezu beliebiger Materialien. Der Aufsatz endet mit einer Zusammenfassung literaturbekannter Erfolge und einer Abschätzung von noch vorhandenen Problemen und Zukunftsaufgaben.
