文摘

Highly ordered and size controlled Ni nanoparticles in Ce-Zr modified SBA-15 nanochannels were achieved. Ce-Zr promoted Ni/SBA-15 shows stable activity in propylene glycol reforming than Ni/SBA-15 catalyst. Higher mobility of surface oxygen species of ceria and zirconia inhibits the carbon deposition. The strong interaction of Ni-ceria and/or zirconia improves the sintering resistance.
