A versatile photoionization detection (PID) system has been developed to rapidly screen libraries of catalytic materials. The PID approach involves the use of an appropriately selected dc discharge lamp to obtain monoenergetic photons, which are then used to photoionize gaseous molecules whose ionization potentials are lower than the photon energy. The suitability of the PID as a rapid screening tool...
Direct oxidation of propylene by oxygen to propylene oxide (PO) has been studied through the application of the techniques of combinatorial catalysis. Catalytic materials containing single and binary metal components were prepared by impregnating standard γ-Al 2 O 3 pellets. In the first stage, 34 single component catalytic materials at three different metal loading levels were prepared...
