The mixture was stirred at 110°C until the water had completely volatilized and then calcined at 500°C in air for 3 hours. The Cu/ZnO/Al 2 O 3 catalyst was prepared by coprecipitation analogous to the procedure described by Behrens and Schlögl . Aqueous solution ... A diffuse reflectance FTIR study: Part II.
Diffuse Reflection (DRIFTs) (rough surfaces) FTIR Reflection Techniques . FTIR Reflection Techniques • Infrared beam reflects from a interface via total internal reflectance • Sample must be in optical contact with the crystal • Collected information is from the ... abrasive material grinding of sample
