Embodiment Construction

[0048] Best Mode for Carrying Out the Invention

[0049] Referring now to the Figures, an apparatus in which the continuous process of the present invention for producing nanoscale metal particles may be practiced is indicated generally by the reference numeral 10 or 100 . exist figure 1 and 2 , the apparatus 10 is a closed system comprising a closed reactor vessel 20, and in Figure 3-5 In the example, the apparatus 100 is a flow-through reaction apparatus including a flow-through reactor vessel 120 .

[0050] It should be noted that Figure 1-5 The device 10, 100 is shown in a particular orientation. However, it should be appreciated that other orientations are equally suitable for the device 10,100. For example, the reactor vessel 20 may be in any orientation for effectiveness when under vacuum. Likewise, in the flow-through reactor vessel 120, Figure 3-5 The flow of the inert carrier gas and the decomposable moieties or the flow of the decomposable moieties drawn b...

Abstract

A continuous process and system for producing nano-scale metal particles includes feeding at least one decomposable moiety selected from the group consisting of organometallic compounds, metal complexes, metal coordination compounds and mixtures thereof into a reactor vessel (20); exposing the decomposable moiety to a source of energy sufficient to decompose the moiety and produce nano-scale metal particles; and depositing or collecting the nano-scale metal particles.

Description

technical field [0001] The present invention relates to the continuous preparation of nanoscale metal particles for catalytic and other applications. By practicing the present invention, nanoscale metal particles can be prepared and collected with greater speed, precision and flexibility than can be accomplished with conventional processes. Thus, the present invention provides a practical and cost-effective system for preparing such nanoscale metal particles. Background technique [0002] Catalysts are becoming ubiquitous in modern chemical processing. Catalysts are used in the production of materials such as fuels, lubricants, refrigerants, polymers, pharmaceuticals, etc., and play an important role in water and air pollution mitigation processes. In fact, catalysts are thought to play a role in a full third of the physical GNP of the United States, as described by Alexis T. Bell in "The Impact of Nanoscience on Heterogeneous Catalysis" (Science, Vol. 299, pp. 1688, 2003 ...
