摘要: Abstract Dielectric barrier discharge (DBD) plasma was applied for the decomposition of nickel nitrate under air at ∼150 °C. Calcination (at 500 °C) and hydrogen reduction thermally were then conducted. The obtained Ni/SiO 2 catalyst investigated steam reforming methane (SRM) reaction temperatures 600, 700 800 °C with a very low to molar ratio (H O/CH 4 = 0.5), in order test coke resistance catalyst. DBD prepared possesses an average particle size 5.5 nm, much smaller than 15.3 nm calcined one. can lead enhanced over carbon nanotubes on used are different from those formed is excellent further investigation effect structure beyond
