翻译 In the case of Cu/γ-Al2O3, metal particles
In the case of Cu/γ-Al2O3, metal particles, with size in the 3–9 nm range, form quite dense ensemble on the support (figure 1A). Passing to the Cu/Fe2O3 system, Cu particles appeared more homogeneously located on the support, and their size distribution, although spread between the same limit values, exhibited a significantly higher presence of particles with size in the 4–7 nm domain (figure 1B). Finally, the Cu/TiO2 catalyst was found to contain very small Cu particles, highly homogeneously distributed on the TiO2 grains and with size essentially confined between 1 and 3 nm (figure 1C). In all samples the HRTEM analysis indicated the presence of a narrow distribution of quite small Cu particles, averaging 6.0 nm in diameter in the Cu/γ-Al2O3 and Cu/Fe2O3 samples and 2.2 nm in the Cu/TiO2 sample.
The Cu particle sizes are largely are quite small pointing out the powerful of solvated metal atoms in the generation of nanosized supported metal particles homogeneously distributed [27].

就Cu/γ-Al2O3 来说,3-9纳米范围内的金属屑,在负载上形成了紧密相连的一体(如图1A所示).转到Cu/Fe2O3体系,铜屑同样也在负载上显现,它们的大小尺寸都在相同的限值范围内分布,并在4–7 nm的大小范围内以一个相当明显地形式体现出来(如图1B所示).最终,Cu/TiO2催化剂中可以发现有有少量铜屑存在,同样,也极其明显地分布在TiO2颗粒上,而且大小也精确地限制在1和3nm(如图1C所示).所有样本中,根据高倍显微镜显示,可以发现微小铜屑的分布范围很小,Cu/γ-Al2O3 和 Cu/Fe2O3的样本中的平均范围直径为6.0 nm,Cu/TiO2 样本中得平均范围直径为2.2 nm
铜屑的大小足以显示了金属原子溶解物中纳米负载金属屑分布状态的生成中产生的能量
