Nano- and Microparticles of Iron with a Modified Surface and Prospects for Their Application. Part II: Chemical and Galvanic Methods of Treatment of Iron Particles

摘要

The possibility of the application of nano- and microparticles of iron as the carriers for palladium and platinum catalysts are shown. An increase in the efficiency of the catalytic activity by 2-5 times is found to be reached by way of microstirring of the reaction medium using magnetic fields with a variable direction of the intensity gradient. The possibility of manufacturing composite materials of iron-silver and iron-gold is also shown, which can be used in electric engineering. The techniques for producing catalytic and conducting materials based on the chemical depositing of certain metals on iron particles arc described. Galvanic methods were shown to be used for the development of metal shells on the particles of magnetic current-conducting materials.
