Scholarcy highlights

  • This paper describes the synthesis of a group of meso-xLaNiAl catalysts with ordered mesostructure and La promoters, and their catalytic performance for hydrogen production from ethanol steam reforming
  • The conventional 0LaNiAl catalyst was prepared by impregnation with γ-Al2O3
  • The characterization results exhibited that meso-xLaNiAl materials possessed excellent textural properties, such as high specific surface areas, large pore volumes and uniform pore sizes
  • The highest initial activity at 873 K is exhibited over meso-3LaNiAl catalyst, which is mainly attributed to the highly dispersed nickel nanoparticles and abundant active surface areas
  • Besides the excellent textural properties, the presence of La-modifiers enhanced the basicity of the catalyst, strengthened the metal-support interaction and cleaned the deposited carbon, resulting in the suppression of carbon deposition and the improvement of stability
