摘要: Abstract The aggregation of nickel supported on amorphous carbon during heating in vacuum and at how hydrogen pressures the temperature range 1000 K was investigated by means high resolution electron microscopy, diffraction microdiffraction. It established that interaction highly dispersed with substrates is strong enough to break away atoms from bulk relatively low temperatures (∼ 700 K) Carbon dissolved precipitate as graphite. As a result accompanied conversion substrate graphitic carbon.
