NiO和In2O3@Ni的Ni−O配位分别在3.9和4.2 Å−1处产生了WT强度最大值,而与Ni−Ni配位相关的最大强度在6.8 Å−1处只能在Ni箔上观察到,这进一步说明In2O3@Ni中的Ni物种是原子分散的,没有聚集。 Fig.2. (a) Ni K-edge EXAFS s...
Ni含量在3-20 wt%范围内,silicalite-1分子筛均呈现为规整的中空六棱柱形貌,即使负载量高达20 wt%,Ni颗粒的平均粒径仍为4-5 nm。 ▲Fig. 1. Characterization of the samples during different synthesis stages. (a) XRD patterns of the DR-...

(XANES) spectra. The NiCuCr spectrum was close to that of Ni foil, demonstrating the metallic form of Ni in the NiCuCr. However, compared with Ni foil, NiCuCr went to a higher valence state with regard to the adsorption edge position, revealing the charge transfer out of Ni, which was...
