文摘
- •
Thermal treatment of support in nitrogen atmosphere leads to most active catalyst (5CMLa–N2) for ammonia decomposition.
- •
The interaction of Mg, La and Co varied with support thermal treatment in different atmospheres (N2, Air, Vaccum).
- •
The surface metal concentration was increased in 5CMLa–N2catalysts.
- •
The moderate basic site density was increased in 5CMLa–N2catalysts compared with other catalysts.
