EPR Study of Furan Compounds Adsorbed on Cu() Y Zeolite

[摘要] The EPR absorption of furan compounds adsorbed on CuY zeolite was studied. With the adsorption of furan on CuY a new high field having a width of 8 gauss and g-factor of 2.002 appeared in EPR spectrum, while the original signal of Cu(¥±) decreased. When 2-methylfuran was adsorbed on Cu(15)Y a new absorption band with a hyperfine structure appeared. With the increase of the degree of Cu(¥±) ion exchange the resolution of the hyperfine structure became poor. The appearance of the new band was interpreted in terms of the formation of a charge transfer complex between Cu(¥±) ion and the furan ring.
