摘要：

Very small Pt particles (6-8 angstrom) located inside pores of silicalite have been prepared. These Pt particles exhibit peculiar behaviour towards H-2 chemisorption (H/Pt = 2). Infrared studies indicate the presence of hydrogen species vibrating at 3200 cm-1 which are tentatively correlated to extra hydrogen chemisorbed. (C) 1994 Academic Press, Inc.
