摘要:
Water-in-CO2 (W/C) microemulsion technology offers a new environmentally friendly approach for the synthesis of a variety of metal nano-particles in supercritical CO2 using water-soluble reagents as starting material. W/C microemulsions have unique advantages over conventional water-in-oil (W/O) microemulsions because of the use of environmentally benign, cheap, and recyclable CO2 as the continuous phase in place of organic solvents. In this review, we will discuss some recent progress on the preparation and applications of metal nano-particles prepared in W/C microemulsions. (C) 2003 Elsevier Ltd. All rights reserved.
