光催化材料原位红外池系统的研制

光催化可利用充足的太阳能分解水制氢以及降解各种有机污染物, 同时还可以将CO₂还原成有机低碳燃料, 是解决当今所面临的能源和环境问题最理想的技术途径之一.目前, 红外光谱仪只能对光催化材料的分子结构进行常规分析, 无法对其进行光照过程的实时监测, 也无法实现光照时光催化反应机理的实时探测与表征.光催化材料原位红外池系统可以实现光催化材料光照过程的实时监测, 从而解析原位红外光催化的反应机理, 实现光照时光催化材料反应机理的实时探测与表征.系统为光催化材料的测试研究提供了有力的技术保障, 是红外光谱仪功能开发的重要技术创新.

Development of In-Situ Infrared Spectroscopic Cell System for Photocatalytic Materials

Photocatalysis is one of the most ideal technology to solve the energy and environmental problem, which could make use of sufficient solar energy to decompose water to H₂, degrade various organic pollutants, and reduce CO₂ to organic low-carbon fuel.The present infrared spectrometer can only be used to analyze the molecular structure of photocatalytic materials in a conventional manner, which cannot investigate the illumination process in real time, and cannot realize the real-time detection and characterization of the change of photocatalytic material and reaction mechanism during the illumination process.An in-situ infrared spectroscopic cell system for the photocatalytic materials has been designed to provide a real-time detection and characterization of catalytic materials during the illumination process, so as to analyze the reaction mechanism of in-situ infrared photocatalysis and realize the real-time detection and characterization of the reaction mechanism of photocatalytic materials.The system provides a strong technical support to study the real-time structure change of photocatalytic materials, and is a very important technical innovation for the functional development of infrared spectrometers.
