Outline of Final Research Achievements

In order to improve the life time of Y Zeolite catalyst we tried to develop a LPCVD enables intermediate substances to flow into micropores of Zeolite to deposit thin film for suppressing catalytic activity. we had started to assembled low pressure thermal CVD apparatus accompaning with continuous pressure reduction system since 2012. We also conducted fundamental experiments to measure the growth rate distribution of obtainined films depending various pressure(10 to 1700 Pa), various temperature(773K to 1173K), and various total flow rates(to max 100SCCM Nitrogen gas as carrie gas). In the above conditions, we were able to get one ideal film with smooth surface which were grown under 973K. We suppose a surface reaction rate is in a limiting step for growth. As future challenges we need to search a CVD mechanism occuring and an optimising the growth condition using the same apparatus.
