文摘
- •
Methane decomposition was studied over various silica supported Ni catalysts.
- •
The crystalline structure of the support improves the metal dispersion.
- •
Different types of carbon nanomaterials were obtained based on the support nature.
- •
CNTs were grown on crystalline silica support whereas GNS were obtained on amorphous silica.
