Design and Application of an in situ FTIR System for Heterogeneous Catalytic Reaction

摘要: 设计和建立了一套能耐高温的用于多相催化反应研究的原位红外系统,反应温度可从室温到1150K,系统真空度为1.0×10⁵～1.0～10^-4Pa,红外光谱检测范围为4800～200cm^-1.此系统扩展了原仪器的功能,提高了仪器的利用率和效率.

Abstract: An in situ FTIR system which can endure hig hreaction temperature for heterogeneous catalytic reaction is desigened and set up. The reaction temperature of the systemform can be from room temperature to 1 150 K,with vacuum from 1.0×10⁵Pa to 1.0×10^-4 Pa, and the IR spectral range is 4800cm^-1 to 200cm^-1. The sample can be easily loaded. The function of the Bruker IFS 120HR FTIR spectrometer is extended and the efficiency of the measurement was also improved.
