โœฆ Synopsis

It IS shown that surface heterogeneity can mduce sustined lunetic oscillations, when a sunple, isothermal reaction occurs on a catalyttc surface Moreover, the proposed model demonstrates that these osctllatlons may occur for reahstlc values of surface heterogeneity Simple crrtena have been developed, for predlctmg the kmetx parameters for which a umque, unstable steady-state solution exists iNTRODUC!TION
