Abstract:	摘要： AbstractNi nanoparticles (around 4 nm diameter) were successfully supported on cage‐type mesoporous silica SBA‐16 (denoted as NiSBA‐16) via wet impregnation at pH 9, followed by the calcination‐reduction process. The NiSBA‐16 catalyst with a very high Ni loading amount (22.9 wt %) exhibited exceptionally high CH4 selectivity for CO2 hydrogenation. At a nearly identical loading amount, the NiSBA‐16 catalysts with smaller particle size of Ni NPs surprisingly exhibited a higher catalytic activity of CO2 hydrogenation and also led to a higher selectivity on CH4 formation than the NiSiO2 catalysts. This enhanced activity of the NiSBA‐16 catalyst is suggested to be an accumulative result of the advantageous structural properties of the support SBA‐16 and the well confined Ni NPs within the support; both induced a favorable reaction pathway for high selectivity of CH4 in CO2 hydrogenation. 出版者： Wiley 出版日期： 2016-08-17 出處： ChemSusChem, 2016-08, Vol.9, p.2326-2331 識別號： ISSN: 1864-5631 識別號： EISSN: 1864-564X 識別號： DOI: 10.1002/cssc.201600710
