摘要

在本文中，我们报告了如何组装一个DRIFTS系统，该系统可以使用易于获取的组件精确控制电池内的压力，从<；10−6托到大气压。作为原理证明，我们在Pd/Al2O3催化剂上吸附和反应CO，我们可以观察到压力，温度和反应依赖于吸附位点的优先结合。

Using precise gas exposures to resolve surface site filling in diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS)†

In this communication we report how to assemble a DRIFTS system that can precisely control the pressure in the cell from <10⁻⁶ Torr to atmospheric pressure using easily accessible components. As a proof-of-principle we adsorb and react CO over a Pd/Al₂O₃ catalyst where we can observe pressure, temperature, and reaction-dependent preferential binding to adsorption sites.
