组合库的有效平行筛选是高通量(HT)多相催化工作流中最具挑战性的难题之一。目前,已有包括各种光学、质谱分析以及气相色谱技术在内的大量方法用于高通量催化剂研究。在这些技术中,快速扫描傅里叶变换红外(FTIR)成像是最快、最通用的筛选技术。本文介绍了16通道高通量反应器的新设计,并给出了其准确性和重复性试验结果。该系统的性能,通过在不同的还原剂-还原剂摩尔比、表面活性剂类型、金属和表面活性剂浓度、合成温度和升温速率下合成的商用Pd/Al_2O_3和氧化钴纳米粒子的一氧化碳氧化反应进行评估。
Effective parallel screening of combinatorial libraries is one of the most challenging challenges in high-throughput (HT) heterogeneous catalytic workflows. Currently, a large number of methods have been developed for high-throughput catalysts, including various optical, mass spectrometry and gas chromatography techniques. Among these technologies, Fast Scanning Fourier Transform Infrared (FTIR) imaging is the fastest and most versatile screening technique. This article describes the new design of a 16-channel high throughput reactor and gives its accuracy and repeatability test results. The performance of this system was optimized by the carbon monoxide oxidation of commercial Pd / Al 2 O 3 and cobalt oxide nanoparticles synthesized at different reductant-reductant molar ratios, surfactant types, metal and surfactant concentrations, synthesis temperatures and heating rates to evaluate.
