Transport and Crystallization of Noble Platinum in Supercritical C-O-H Fluid
Abstract
Experimental data is provided for the transport of platinum in a supercritical C-O-H fluid system. The transfer of platinum in space with its condensation on the surface of native carbon (diamond and amorphous carbon) in the form of micro- and nanocrystals, shapeless particles, and filamentous formations is established for the first time. The dominant participation of platinum in the formation of carbon micro- and nanotubes is demonstrated. The results are important in modeling the formation of noble metal deposits with deep fluid carbon systems.
