The strongest metal-support interaction in Rh/Al2 O3 is attributed to the highest interfacial Rh–O–Al bond from the results of XAFS and NMR. The smallest particle size and highest redox property on Rh/Al2 O3 led to the highest NH3 yield below 300 °C. Pt/Al2 O3 produced more NH3 ...
The mechanism of the self-regenerative function is studied by X-ray absorption fine-structure (XAFS) analyses. The function was realized through a cyclic movement of Pd between the outside (as Pd nanoparticles) and the inside (as Pd cations in the lattice) of the perovskite crystal in ...
XAFSIt was reported that the innovation of "An Intelligent Catalyst" which has the self-regenerative function of Pd, and the development for application to the Japanese ULEV standard. In this paper, the answer for a left-behind big question was replied to. It was whether the self-regenerative...
We present Pt L_3-edge grazing incidence x-ray absorption fine structure (GIXAFS) and high energy resolution fluorescence detection (HERFD) XAS measurements of Pt/Rh(111) in 0.01 M HClO_4 solution. In the HERFD-XAS experiment, we used a multi-crystal analyzer to suppress the core hole ...
