在这一研究中获得的结果已经过了三年了，如以下所示。2.在palladized Pd sheet上的氢化中，对烯烃的选择性进行了评估，作为烯烃到烯烃的生产率的比率，增加了目前原子氢的生产中的一个增加。在α，β-未饱和的醛与C=C和C=平行化Pd表上的O键，C=C键与饱和的醛完全氢化。关于加载Pt的pallazized Pd表，不仅仅是C=C键，但也是C=O被氢化成饱和的醛和不饱和的酒精，建议将产品的分布依赖于加载金属的种类。In the reduction of NイイD22エD2O gas on a palladized Pd sheet， NイD22エD2 was solely produced。在降低硝酸盐溶液、硝酸盐和N-D22-D2可靠地在一个铜填充的钯化Pd表上生产，同时氨在一个镍填充的钯化Pd表上可靠地生产。一个新的脱氢系统是由一个通过钯化的Pd板组合而成的正酸的脱氢生成和潜在的静态氧化的原子氢氧化物。从氧化电流的时间过程中对渗透原子氢的氧化电流和氢的扩散协同作用的时间过程中进行了理论分析，并在与先前评估的值一致的情况下得到了很好的评价。

The result obtained in this study for three years are summarized as follows.1. In the hydrogenation of alkyne on a palladized Pd sheet, the selectivity of alkane, which was evaluated as the ratio of the production rate of alkane to alkane, increased with an increase in current for the production of atomic hydrogen.2. In the hydrogenation of α,β-unsaturated aldehyde with C=C and C=O bonds on a palladized Pd sheet, the C=C bond was solely hydrogenated to saturated aldehyde. On Pt-loaded palladized Pd sheet, not only C=C bond but also C=O were hydrogenated to saturated aldehyde and unsaturated alcohol, suggesting that the distribution of product depended on the kind of the loaded metal.3. In the reduction of NィイD22ィエD2O gas on a palladized Pd sheet, NィイD22ィエD2 was solely produced. In the case of the reduction of nitrate solution, nitrite and NィイD22ィエD2 were consecutively produced on a Cu-laded palladized Pd sheet while ammonia was solely produced on a Ni-loaded palladized Pd sheet.4. New dehydrogenation system was constructed by combining the dehydrogenation of formic acid with potentiostatic oxidation of atomic hydrogen permeating through the palladized Pd sheet. From a theoretical analysis of time course of the oxidation current of permeated atomic hydrogen, the diffusion coefficient of hydrogen was evaluated and it was in good agreement with the previously evaluated value.
