Special Issue Information

Dear Colleagues,

Combinatorial and high-throughput (CHT) technologies for the discovery and optimization of catalysts have now become an indispensable tool for catalysis research. Including biosciences, the actual number of Scifinder entries on this topic is more than 11,000. CHT technologies couple the capability of parallel production of arrays of catalyst libraries with different high-throughput measurement techniques for catalytic performance properties. “Lead” materials can then be ascertained by data mining of collected data. CHT technologies include also dynamic or reversible chemistry approaches as self-assembly, self-selection or self-evolving libraries. The already generated impressive set of tools for productivity acceleration demonstrates the broad applicability of CHT experimentation technologies in catalysis. This is the foundation for continuing, substantial improvements in the efficiency and economics of catalytic processes.

This Special Issue focuses on recent advances in catalyst discovery and optimization via combinatorial and high-throughput methods in homogeneous and heterogeneous catalysis, as well as in biocatalysis. The Special Issue scope also includes methodological and theoretical approaches and developments. The Special Issue further aims to establish this matured field by monitoring recent developments in catalyst synthesis, characterization, and data mining. Also, industrial applications of catalyst developments are welcome, especially when they illustrate successful applications of high-throughput technologies.

A high-throughput (HT) screening platform developed at hte with the application focus on automotive catalysis is described. hte HT units are configured for performing steady-state testing, as well as dynamic tests with fast feed switches, such as lean/rich excursions for the evaluation of NOx storage capacity and efficiency of lean NOx traps (LNT), ammonia storage capacity for selective catalytic reduction (SCR), evaluation of oxygen storage capacity (OSC), as well as lambda sweep tests for screening of three-way catalysts (TWC). Even though catalysts are screened on a rather small scale (~100 mg powder), experience showed that dosing rather complex gas mixtures in concentrations close to that found in real exhaust for the given application is mandatory to generate relevant data. The objective of this work is to give additional insight into HT technology. In the industrial research laboratory, HT screening has matured to become a reliable approach for rapid screening of both reaction parameter spaces, as well as material properties relevant for exhaust gas catalyst development. Due to the speed of optimized screening involving 48 parallel reactors, automated handling of primary data is an imported requirement. Software for data reduction, like estimation of light-off temperature, needs to be robust and handle results for diverse sample libraries in an unattended fashion. In combination with the statistical design of experiment and multivariate data analysis, HT testing has become a valuable enhancement to automotive catalyst development. Full article

A novel methodology is presented for more comprehensive catalyst development by maximizing the acquired information rather than relying on statistical methods or tedious, elaborate experimental testing. Two dedicated high-throughput kinetics (HTK) set-ups are employed to achieve this objective, i.e., a screening (HTK-S) and a mechanistic investigation one (HTK-MI). While the former aims at evaluating a wide range of candidate catalysts, a limited selection is more elaborately investigated in the latter one. It allows focusing on an in-depth mechanistic analysis of the reaction mechanism resulting in so called “kinetic” descriptors and on the effect of key catalysts properties, also denoted as “catalyst” descriptors, on the catalyst performance. Both types of descriptors are integrated into a (micro)kinetic model that allows a reliable extrapolation towards operating conditions and catalyst properties beyond those included in the high-throughput testing. A case study on ethanol conversion to hydrocarbons is employed to illustrate the concept behind this methodology. The methodology is believed to be particularly useful for potentially large-scale chemical reactions. Full article
