Spectroscopic investigation of the influence of Ni particle size in CO2 methanation
{{output}}
CO2 methanation was investigated over Ni/Al2O3 catalysts with Ni nanoparticle sizes ranging from 4.6 to 8.4 nm. Particle sizes were determined using electron microscopy and CO chemisorption measurements. The turnover frequency (TOF) increased from 0.005 s-1 to... ...
