Abstract: Rh@Pt core-shell, RhPt (1:1) alloy, and Rh + Pt monometallic nanoparticles (NPs) were prepared
using standard polyol reduction chemistry in ethylene glycol (EG) with standard inorganic salts and
polyvinylpyrrolidine (PVP55000) stabilizers. PVP-free colloids were also prepared but less stable than the
PVP-protected NPs. Rh@Pt core-shell particles were prepared from 2.7, 3.3, and 3.9 nm Rh cores with
varying shell thicknesses (∼1 and ∼2 ML). The particles were characterized by a combination of TEM,
single-particle EDS, EDS line scans, XRD analysis, Debye Function simulations, FT-IR, and micro-Raman
CO-probe experiments. The three different architectures were evaluated for preferential oxidation of CO in
hydrogen (PROX) using 1.0 wt % Pt loadings in Al2O3 supports. For hydrogen feeds with 0.2% CO and
0.5% O2 the Rh@Pt NP catalyst has the best activity with complete CO oxidation at 70 °C and very high
PROX selectivity at 40 °C with 50% CO conversion.

不知是不是指一个或者两个分子层,就是包两层或者一层Pt包着,

"法语的毫米是 millemètre,一般按国际惯例缩写成mm,我想这个法国客户是按自己的方式缩写的ml,理解成毫米就行了。"

peng0701(金币+1,VIP+0):对,是分子层 1-13 16:34
毫米也忒大了吧, 太离谱了
应该是分子层
