“…The application of high throughput, combinatorial screening methods to screen a large number of catalysts using an optical fluorescence technique by detecting proton production on an array of catalyst inks with different compositions has been successfully demonstrated. 8,19 Individually addressable array electrodes have also been investigated for rapid screening. [20][21][22] Recently, simple thermodynamic principles are proposed as guidelines that assume that one metal breaks the oxygen-oxygen bond of O 2 and the other metal acts to reduce the resulting adsorbed atomic oxygen.…”

Fuel cells represent an attractive technology for tomorrow's energy vector because hydrogen is an efficient fuel and environmentally clean, but one of the important challenges for fuel cell commercialization is the preparation of active, robust and low-cost catalysts. The synthesis and processing of molecularly-capped multimetallic nanoparticles, as described in this report, serves as an intriguing way to address this challenge. Such nanoparticles are exploited as building blocks for engineering the nanoscale catalytic materials by taking advantage of diverse attributes, including monodispersity, processability, solubility, stability, capability in terms of size, shape, composition and surface properties. This article discusses recent findings of our investigations of the synthesis and processing of nanostructured catalysts with controlled size, composition, and surface properties by highlighting a few examples of bimetallic/trimetallic nanoparticles and supported catalysts for

Robotic Catalysis: A High‐Throughput Method for Miniature Screening of Mesoporous Metal Oxides**

et al. 2020

We have developed a high-throughput system to synthesise and explore up to 96 heterogeneous catalysts at the same time.The system was developed as a proof of concept, using a standard glass plate and a 3D printed 96-well plate. Nanodroplets of catalyst formulations were transferred to the glass plate using an acoustic liquid handler and upon heat treatments, the miniature mesoporous metal oxide (MMO) catalysts were formed. The 3D printed bottomless 96-well plate was fixed to the glass plate, to give 96 individual wells, each containing a catalyst. Four catalyst plates were prepared (Co 3 O 4 -, Au/Co 3 O 4 -, Pd/Co 3 O 4 -and Co/Mn-MMO) to be screened for their activity in the oxidation of morin, as a model reaction. The observed reaction rates (k obs ) for each catalyst were calculated to identify the most active catalyst. The general method described herein requires microscopic amounts of catalysts with derivates of the catalyst's composition.

“…These methods (parallel synthesis and screening) are being implemented to reduce the time and cost of compound optimisation from a hit with relatively low affinity with a protein, to a lead that can progress to a future clinical stage of the drug development. In recent years, these methods have also been adapted for the discovery and optimisation of catalysts [31]. The terms high-throughput and/or combinatorial approach may also refer to the automated parallel or rapid sequential synthesis or evaluation of materials [32].…”
