Belousov-Zhabotinsky(BZ) reaction for CO oxidation

（1）D原子与D覆盖Pt （111）表面的相互作用已通过直接产品方法和TPD （温度编程降解）特性研究。首先， D原子被暴露在清洁Pt （111）表面上的D覆盖超过了表面饱和覆盖。我们发现D原子被吸收到表面上，吸收到大块中。我们已经研究了两个被设计的D22 D2的机制，通过TPD技术。我们将第二次订单反应结合在一起，以防止D2分子反应。（2） Platinum是一种众所周知的催化剂，用于氢和氧之间的反应，两个实验已经被TPD Spectra试过对其进行调查。（I） Intensity of D22 D2O desorption， after D atoms are exposed at O adsorbed Pt （111） surface。（ii）D22 D2O下降强度后，O原子在D Adsorbed Pt （111）表面暴露，我们在170 K和210 K上发现了两个相同的峰值温度，但这些在170 K上明显不同的下降机制。对于（I），D22 D20在表面暴露于170 K上发现了两个相同的实验，D22 D2O formed from OD bond at surface by TPD is desorbed at 210 K。For （ii）、D22 D2O is desorbed on the reaction of OD bond on surface with desorbed D atoms from the bulk at 170 K by TPD、D22 D2O is desorbed at 210 K as same as （I）mManagement ism。

(1) The interaction of D atoms with D covered Pt (111) surfaces was studied with direct product methods and TPD (temperature-programmed desorption) spectra. First, D atoms are exposed with clean Pt (111) surface at D coverage more than the surface saturation coverage. We found D atom is adsorbed on the surface and absorbed into the bulk. We have investigated two mechanism of desorbed DィイD22ィエD2 through TPD technique. We concluded second orders reaction for reaction of desorbed D2 molecules.(2) Platinum is a well-known catalyst for the reaction between hydrogen and oxygen.Two experiments have been tried to investigate for it by TPD spectra.(I) Intensity of DィイD22ィエD2O desorption, after D atoms are exposed at O adsorbed Pt (111) surface.(ii) Intensity of DィイD22ィエD2O desorption, after O atoms are exposed at D adsorbed Pt (111) surface.We found for two experiment same two peak temperatures at 170K and 210K by TPD spectra have been observed, but these are quite different desorption mechanisms at 170K.For (I), DィイD22ィエD20 formed at surface is desorbed at 170K by TPD, and DィイD22ィエD2O formed from OD bond at surface by TPD is desorbed at 210K.For (ii), DィイD22ィエD2O is desorbed on the reaction of OD bond on surface with desorbed D atoms from the bulk at 170K by TPD, and DィイD22ィエD2O is desorbed at 210K as same as (I) mechanism.
