Abstract

The long-order structure of micro porous silica thin films, deposited on Si substrates was improved by pH adjustment of the synthesis mixture to 2.0 during the hydrolysis of TEOS. It was further improved by incorporation of Al at an Al/Si ratio of 0.005. After exposure to non-polar solvents, the long-order structure was still present after 48 hours. The samples with an Al/Si ratio of 0.007 showed the smallest d-spacing shift after exposure to hexane. The stability was tested in the hydrogenation of phenyl acetylene perfonued over 1 wt% Pd/Si(Al)02/Si (A1/Si=0.007) films at 30 ‘C and 10 bar H2 with hexane as solvent. No deactivation was observed in two subsequent hydrogenation runs.
