Ni-La2O3-Ce0.8Zr0.2O2 catalysts with various La2O3 loading were investigated for hydrogen production from steam reforming of methane (SRM). The La2O3 loading influenced the physicochemical properties of Ni-La2O3-Ce0.8Zr0.2O2 catalysts such as BET surface area, Ni dispersion, Ni size and reducibility. Among the prepared catalysts, Ni-70La2O3-Ce0.8Zr0.2O2 catalyst showed the highest activity and stability at a very high gas hourly space velocity (GHSV) of 932,556 h-1.
<br>This is mainly due to high Ni dispersion, small Ni size and high reducibility.
