使用傅里叶变换红外成像进行高通量筛选
High-Throughput Screening Using Fourier-Transform Infrared Imaging
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/Al2O3和氧化钴纳米粒子的一氧化碳氧化反应进行评估。
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 gas-chromatography 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 reducer-reductant molar ratios, surfactant types, metal and surfactant concentrations, synthesis temperatures, and ramp rates.
