What Are the Techniques Used in IR Spectroscopy for Catalysis?
Several techniques are employed in IR spectroscopy for catalytic studies, including:
Transmission IR Spectroscopy: Where the IR radiation passes through a sample, and the transmitted light is analyzed. Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS): Suitable for studying powders and rough surfaces, it measures the scattered IR radiation. Attenuated Total Reflectance (ATR) IR Spectroscopy: Involves measuring the IR radiation that reflects off a sample surface, useful for analyzing liquid and solid samples. In Situ IR Spectroscopy: Allows real-time monitoring of catalytic reactions under actual reaction conditions.
