GEMStar-CAT Dual™ Dual Reactor ALD and Catalyst Synthesis System by Arradiance

US ALD company Arradiance has released a new version of their GEMStar series of ALD tools -The GEMStar-CAT Dual™ Dual Reactor ALD and Catalyst Synthesis System. The custom GEMStar-DUAL CatalystTM System developed in partnership with the Chemical Sciences and Engineering Division of Argonne National Laboratory has unique capabilities. Arradiance used its skill combining Atomic Layer Deposition, System Design and Controls to produce a system that is unparalleled for Catalyst synthesis research

An integrated atomic layer deposition synthesis-catalysis (I-ALD-CAT) tool was developed. It combines an ALD manifold in-line with a plug-flow reactor system for the synthesis of supported catalytic materials by ALD and immediate evaluation of catalyst reactivity using gas-phase probe reactions. The I-ALD-CAT delivery system consists of 12 different metal ALD precursor channels, 4 oxidizing or reducing agents, and 4 catalytic reaction feeds to either of the two plug-flow reactors. The system can employ reactor pressures and temperatures in the range of 10−3 to 1 bar and 300–1000 K, respectively. The instrument is also equipped with a gas chromatograph and a mass spectrometer unit for the detection and quantification of volatile species from ALD and catalytic reactions. In this report, we demonstrate the use of the I-ALD-CAT tool for the synthesis of platinum active sites and Al2O3 overcoats, and evaluation of catalyst propylene hydrogenation activity. © 2015 AIP Publishing LLC.
