来自复旦大学的卢建忠课题组设计出了正己烷催化化学发光传感器。该研究发表在Anal.Chem.,2007,79(4),1425-1432。该传感器基于固体催化剂表面的化学发光,不需要光源,也没有发光试剂不断被消耗和脱落的缺点。相比于常见的催化剂,分子筛催化剂具有均匀的通道和空腔,能够有效筛分特定的反应物和产物,很好地识别结构相似的同系物。此外,其酸碱性可通过离子交换加以调节,为改善气体传感器的选择性和灵敏度提供新的思路。
Lu Jianzhong from Fudan University team designed a n-hexane catalytic chemiluminescence sensor. This study is published in Anal. Chem., 2007, 79 (4), 1425-1432. The sensor is based on the chemiluminescence of the solid catalyst surface, does not require a light source and has the disadvantage that the luminescent reagent is constantly depleted and shedding. Compared with the common catalysts, the molecular sieve catalyst has uniform channels and cavities, which can effectively screen specific reactants and products and well recognize structurally similar homologs. In addition, its acid-base can be adjusted by ion exchange, to provide new ideas for improving the selectivity and sensitivity of gas sensors.
