Efficient parallel screening of combinatorial libraries is one of the most challenging aspects of the high-throughput (HT) heterogeneous catalysis workflow.Today,a number of methods have been used in HT catalyst studies,including various optical,mass-spectrometry,and gaschromatography techniques.Of these,rapid-scanning Fourier-transform infrared (FTIR) imaging is one of the fastest and most versatile screening techniques.Here,the new design of the 16-channel HT reactor is presented and test results for its accuracy and reproducibility are shown.The performance of the system was evaluated through the oxidation of CO over commercial Pd/Al2O3 and cobalt oxide nanoparticles synthesized with different reducerreductant molar ratios,surfactant types,metal and surfactant concentrations,synthesis temperatures,and ramp rates.
