Question

The results of a series of consecutive TPR profiles of fresh and aged catalysts are illustrated in Figure 1. For the fresh catalysts, all of the samples exhibit a dominate low-temperature reduction feature at ca. 65 °C (peak a)andthree small peaks denoted by b, c,anddappeared in the range of 150-400 °C. Previous investigations have
reported that palladium oxide is reduced to palladium on exposure to H2 at room temperature (22, 23). In addition, no characterization was observed below 150 °C in the TPR profiles of fresh supports (not shown), which further proves that peak a can be attributed to the reduction of PdO.
The results of classical TPR experiments for CeO2-ZrO2 mixed oxide show two peaks at 500 and 830 °C, which have been, respectively, attributed to reduction of the surface and the bulk (24). The three peaks in the range of 150-400 °C are also associated with reduction of the surface, and are assigned to reduction of small crystallites, the surface of larger crystallites and some subsurface reduction of the larger crystallites as reported (9, 16, 23). In fact, it was shown that the TPR behavior of these mixed oxides depends on different
factors such as pretreatment conditions, degree of sintering, and phase structure (25-27). In our previous study, we have found that the bulk reduction temperature of CeO2-ZrO2 solid solution increased with the increase of Zr content, and no bulk reduction occurred for Ce0.2Zr0.8O2 in the range of 30-1000 °C. Therefore, the absence of bulk reduction for the corresponding catalyst is easy to understand.
Based on the amount of H2 consumption observed over a standard CuO sample in similar TPR procedures, the amount of mobile oxygen reacted with H2 in the fresh and aged catalysts were estimated and the data are summarized in SI Tables S1 and S2, respectively.
In comparison with the TPR profile of the support, the presence ofPdproduces the well-established overall decrease in the reduction temperature, which indicates that the noble metal particles cause spillover of hydrogen onto the support inducing a concurrent reduction of both the metal oxide and the surface of solid solution (8). Regarding SI Table S1, it was noticed that the total amount of theH2 consumption of peak a is too large to be reasonably attributed to the reduction of noble metal oxides, the theoreticalH2 consumption of which is just 40.84 μmol/gcat, indicating the back-spillover of the oxygen process from the support to the PdO surface (28, 29). Moreover, all the Pd/CZR catalysts showed increased total H2 uptake than Pd/CZ, especially for peak a, indicating that the appearance of rare earth have an effect on the reducibility of both the solid solution and the noble metal. From what has been discussed above, we may draw a conclusion that there is a strong interaction between supports and noble metal (30), and the presence of rare earth shows a promotional effect on this interaction.

The results of a series of consecutive TPR profiles of fresh and aged catalysts are illustrated in Figure 1. For the fresh catalysts, all of the samples exhibit a dominate low-temperature reduction feature at ca. 65 °C (peak a)andthree small peaks denoted by b, c,anddappeared in the range of 150-400 °C. Previous investigations have reported that palladium oxide is reduced to palladium on exposure to H2 at room temperature (22, 23). In addition, no characterization was observed below 150 °C in the TPR profiles of fresh supports (not shown), which further proves that peak a can be attributed to the reduction of PdO.

图1示出了新制和老化的催化剂的一系列连续TPR截图。所有新制催化剂样品呈现出低温为主的还原特性，65°C附近出现峰a，还有三个小峰以b,c表示【注】，而在150-400°C范围内还原性消失。先前的研究报道认为在室温下，氧化钯置于H2中可被还原为金属钯(22、23)。而新制的（催化剂）载体在TPR截图上低于150°C区域未观察到特征峰（该图未在这里给出），这进一步证明峰a可以归属于PdO被还原。

【注】原文此处恐有误，或原文表述不够恰当。

The results of classical TPR experiments for CeO2-ZrO2 mixed oxide show two peaks at 500 and 830 °C, which have been, respectively, attributed to reduction of the surface and the bulk (24). The three peaks in the range of 150-400 °C are also associated with reduction of the surface, and are assigned to reduction of small crystallites, the surface of larger crystallites and some subsurface reduction of the larger crystallites as reported (9, 16, 23). In fact, it was shown that the TPR behavior of these mixed oxides depends on different factors such as pretreatment conditions, degree of sintering, and phase structure (25-27). In our previous study, we have found that the bulk reduction temperature of CeO2-ZrO2 solid solution increased with the increase of Zr content, and no bulk reduction occurred for Ce0.2Zr0.8O2 in the range of 30-1000 °C. Therefore, the absence of bulk reduction for the corresponding catalyst is easy to understand.

CeO2-ZrO2混合氧化物的经典TPR实验结果中出现了两个峰500和830°C，它们分别归属为（混合物）表面和本体的还原(24)。在150 - 400°C之间的三个峰同样与表面的还原有关，它们可归属为小晶粒，较大晶粒（上）表面和下表面的还原，正如文献(9,16,23)报道的那样。事实上，人们业已证明这些混合氧化物的TPR行为依赖于诸如预处理条件、烧结程度、相结构等不同因素(25 - 27)。我们先前的研究发现CeO2-ZrO2固溶体的本体还原温度随Zr含量增大而升高，并且Ce0.2Zr0.8O2在30 - 1000°C的范围内不发生本体还原。因此,对应催化剂不存在本体还原是容易理解的。

Based on the amount of H2 consumption observed over a standard CuO sample in similar TPR procedures, the amount of mobile oxygen reacted with H2 in the fresh and aged catalysts were estimated and the data are summarized in SI Tables S1 and S2, respectively.

根据标准CuO样品进行的类似TPR实验中测出的H2消耗量，可以估算出新制和老化的催化剂中与H2反应的流动氧气量，H2和O2消耗量数据分别汇总在补充材料（SI）的S1和S2表中。

In comparison with the TPR profile of the support, the presence of Pd produces the well-established overall decrease in the reduction temperature, which indicates that the noble metal particles cause spillover of hydrogen onto the support inducing a concurrent reduction of both the metal oxide and the surface of solid solution (8).

对比载体的TPR截图，Pd的存在引起还原温度总体上降低（这业已被公认），这表明贵金属（Pd）粒子引起氢气流向载体表面，诱导金属氧化物和固溶体表面同时发生还原(8)。

Regarding SI Table S1, it was noticed that the total amount of the H2 consumption of peak a is too large to be reasonably attributed to the reduction of noble metal oxides, the theoreticalH2 consumption of which is just 40.84 μmol/gcat, indicating the back-spillover of the oxygen process from the support to the PdO surface (28, 29).

从补充材料的S1表中可见，峰a消耗的H2量太大（理论耗氢量仅为40.84 μmol/gcat），以至于不能归属为贵金属氧化物的还原【注】，这意味着存在自载体流向PdO表面的逆向氧气流。

【注】文章不完整，各部分的逻辑关系不很清楚（作者的表达逻辑个人感觉也有点问题），此处看起来与首段自相矛盾，第一段和后面各段讲的应当不是同一回事。

Moreover, all the Pd/CZR catalysts showed increased total H2 uptake than Pd/CZ, especially for peak a, indicating that the appearance of rare earth have an effect on the reducibility of both the solid solution and the noble metal. From what has been discussed above, we may draw a conclusion that there is a strong interaction between supports and noble metal (30), and the presence of rare earth shows a promotional effect on this interaction.

此外，所有Pd/CZR催化剂显示出比Pd/CZ催化剂更高的H2总吸收量，尤其是峰a，表明稀土的存在对固溶体和贵金属氧化物的还原产生影响。由上文讨论可以得出结论，即载体和贵金属间存在强的相互作用 (30)，而稀土的存在对相互作用具有促进效应。

结果一系列的连续还原概况和老年新鲜催化剂如图1所示。对新鲜的催化剂，所有的样品展示一个占主导地位的低温还原功能在约65°丙（峰）和三个小峰被命名的乙，丙型anddappeared，范围在150 - 400°公元前调查报道钯氧化物还原成钯接触氢在室温（22，23）。此外，没有定性观察低于150°在还原概况新鲜支持（未显示），这进一步证明了峰可以归因于减少丙二醇。结果古典铈锆混合氧化物还原实验表明2高峰在500和830摄氏°，已，分别，由于减少表面和散装（24）。三峰范围在150 - 400°丙也与减少表面，并分配到减少小晶粒，较大的表面和表层晶粒较大的减少晶体的报告（9，16，23）。事实上，这是表明，这些混合氧化物的还原行为取决于不同的因素，如预处理条件下，烧结程度，及相结构（27）。在我们先前的研究中，我们发现，大部分的还原温度铈锆固溶体的增加而增加的锆含量，并没有大量减少发生ce0.2zr0.8o2范围在30 - 1000°角因此，没有大量减少的相应催化剂很容易理解。基于大量的氢气消耗观察一个标准铜样品在类似的还原程序，数额移动氧反应与氢气在催化剂的新鲜和年龄估计和数据汇总在表一和二，分别。在比较与还原文件的支持，存在ofpdproduces既定的总体下降的还原温度，这表明，贵金属粒子产生溢出氢气到支持诱导减少并发的金属氧化物和固体表面的解决办法（8）。有关硅表中，值得注意的是，总金额theh2消费的高峰期是太大，合理归因于减少贵金属氧化物的theoreticalh2消费，这只是40.84μ摩尔/ gcat，表明back-spillover的氧气的过程从支持的表面（28，29-丙二醇）。此外，所有的钯/该催化剂显示增加总氢气摄取比钯/锆石，尤其对峰，表明出现稀土已影响还原的固体溶液和贵金属。通过以上讨论，我们可以得出结论之间存在强的相互作用的支持和贵金属（30），和在场的稀土显示促销效果这种相互作用。(只能帮你帮到这儿了。自己整理整理吧。。）
