Engineering Research Equipment: A Diffuse Reflectance Fourier Transform Infrared Spectroscopy System

粉末表面吸附物种的表征系统 在操作条件下的催化剂被组装。 组件包括傅里叶变换红外（FTIR） 光谱仪，漫反射（DRIFTS）附件，质量 流量控制器和温度控制器。 本设备 将在几项研究中使用，重点是减少 来自固定电源的氮氧化物排放。 的 研究包括一氧化氮和氮的分解 二氧化物对锰氧化物的还原作用， 甲烷对氧化镧或掺杂氧化镁，和表征 使用吸附的一氧化碳的碳载钯。

A system for the characterization of adsorbed species on powder catalysts under operating conditions is being assembled. Components include a Fourier-transform infrared (FTIR) spectrometer, a diffuse reflectance (DRIFTS) attachment, mass flow controllers, and a temperature controller. This equipment will be used in several studies, with emphasis on abatement of nitrogen oxide emissions from stationary power sources. The studies include decomposition of nitric oxide and nitrogen dioxide on manganese oxides, reduction of nitric oxide by methane ovre lanthana or doped magnesia, and characterization of carbon-supported palladium using adsorbed carbon monoxide.//
