Coke yield is a key measurement of catalyst performance and often used in catalyst selection. However, the existing methods for heterogeneous catalyst evaluations are limited by low-throughput, meaning each time only one catalyst can be tested. Barcodes have been used to tag products, but common barcodes attached on packing are not suitable for catalyst evaluation. There is an unmet need to develop a new type of barcodes to label each catalyst, and lots of catalysts can be evaluated simultaneously to save efforts. This paper establishes a high-throughput evaluation system, in which a selected panel of phase change nanoparticles (PCMs) as thermal barcode was embedded into catalyst pellet. Lots of catalysts could be evaluated in one reaction due to the large labeling capacity of the thermal barcode. After the reaction, coke formation was determined by thermogravimetric analysis and the thermal barcode was decoded with a differential scanning calorimeter to correlate with the catalyst composition.

带有热条形码的耐焦炭催化剂的高通量筛选

焦炭收率是催化剂性能的关键指标，经常用于催化剂的选择。但是，现有的多相催化剂评估方法受到低通量的限制，这意味着每次只能测试一种催化剂。条形码已用于标记产品，但包装上所附的常见条形码不适用于催化剂评估。迫切需要开发一种新型条形码以标记每种催化剂，并且可以同时评估许多催化剂以节省工作量。本文建立了一个高通量评估系统，其中将选定的一组相变纳米粒子（PCM）作为热条形码嵌入到催化剂颗粒中。由于热条形码的标记能力强，可以在一个反应​​中评估许多催化剂。反应后
