CO2 reforming of CH4 over M(Ca, Ba, Sr)xLa1-xNiO3 perovskites used as coke resistant catalyst precursor

Methane and carbon dioxide are greenhouse gases that have been converted into synthesis gas for the production of oxygenated chemicals and hydrocarbons. In this paper, M(Ca, Ba, Sr)xLa1-xNiO3 (x = 0.0, 0.3 and 0.5) doped perovskites were successfully synthesized as catalyst precursors aiming at high...
