Preparation of Catalysts by Ion Soft Landing

總結: Researchers at Purdue University have developed a new methodology for preparing catalytic surfaces through molecular soft landing of mass selected ions. The principal advantage of this method is that mass spectrometry allows almost any imaginable combination of atoms in a particular geometrical arrangement to be generated and ion soft landing allows this molecular entity or combination of entities to be selected and then gently deposited onto a surface while remaining intact. Using electrospray ionization, delicate molecular structures or mixtures of structures can be generated and mass selected. Using an ion trap, mass selection of ions can be done prior to landing. The result is a well-controlled selection of the desired catalyst particle size and molecular composition; therefore, catalytic surfaces of known composition can be prepared.

技術優勢: Can define chemical composition of catalytic surfaceControl of catalyst particle size and molecular composition Optimal cluster size and composition

*Background: Most catalytic surfaces involve metal atoms in certain arrangements, sizes, and compositions that lead to high reactivity. Previous studies have shown that both the size and composition of catalytic particles play large roles in the catalytic activity of such surfaces. Existing methods provide some control over the catalyst surface composition, but offer only limited or no control with respect to the size of the active catalyst material. Unless great care is taken, a wide distribution of sizes is often seen. There is a need for methods and apparatuses that can prepare a surface precisely and accurately with a compound capable of having catalytic activity as an ion.
