本文讨论了利用热等离子体和冷等离子体制备催化剂。一般来说，利用等离子体技术制备催化剂有三个主要趋势：（1）等离子体化学合成超细颗粒催化剂;（2）等离子体辅助沉积催化活性化合物在各种载体上，特别是等离子体喷涂制备负载型催化剂;（3）等离子体增强制备或等离子体改性催化剂。与传统的催化剂制备相比，使用等离子体有几个优点，包括：（1）高度分布的活性物质;（2）降低的能量需求;（3）增强的催化剂活化、选择性和寿命;（4）缩短的制备时间。这些优点导致了等离子体制备催化剂的许多潜在应用。(C)2002 Elsevier Science B. V.保留所有权利。
This paper discusses catalyst preparation using thermal and cold plasmas. In general, there are three main trends in preparing catalysts using plasma technologies: (1) plasma chemical synthesis of ultrafine particle catalysts; (2) plasma assisted deposition of catalytically active compounds on various carriers, especially plasma spraying for the preparation of supported catalysts; (3) plasma enhanced preparation or plasma modification of catalysts. Compared to conventional catalyst preparation, there are several advantages of using plasmas, including: (1) a highly distributed active species; (2) reduced energy requirements; (3) enhanced catalyst activation, selectivity, and lifetime; (4) shortened preparation time. These advantages are leading to many potential applications of plasma prepared catalysts. (C) 2002 Elsevier Science B.V. All rights reserved.
