Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) is an infrared technique used on powder samples that is ideal for catalyst surface research. DRIFTS allows evaluation of non-transparent, highly absorbing materials to detect subtle changes on rough surfaces, designed to minimize reflection losses. Understanding surface chemistry is crucial for catalyst innovation and determining modifications that will produce enhanced performance. With DRIFTS, this surface information is attainable.
