(1) Preparation of fabricated surface.The fabricated VSbO_4-Sb_2O_4 catalyst which shows high selectivity for hydrocarbon oxidation reaction under the interaction between the two phases was prepared by electron lithography method. VSbO_4 thin layer was produced by sol-gel technique. After the resist deposition, the patterns were drawn by electron beam. Sb_2O_4 was deposited on it to create the fabricated Sb_2O_4 domain on VSbO_4 surface. The surface was characterized by XPS, XRD and AFM and we found the surface was stable up to 773 K.(2) Improvement of XPEEMWe installed X-ray tube and tried XPEEM measurements. But we found that it took so long a time that we had to use much stronger X-ray source. We are now bringing the system to Photon Factory (SR facility in Tsukuba)(3) Setup of reaction systemWe produced a reaction system under the following design concept a) Fast analysis and high resolution using QMS.b) Reaction under high pressure by using differential pumping. c) Direct heating of samples by IR hearter. d) Combination of SEM, LEED, and AES.e) Fine measurement of temperature by TC
