Hydrogenolysis of polyolefins

This is a major achievement, mainly due to Basset and his group, in surface organometallic chemistry because it has been thus possible to prepare single site catalysts for various known or new catalytic reactions [53] such as metathesis of olefins [54], polymerization of olefins [55], alkane metathesis [56], coupHng of methane to ethane and hydrogen [57], cleavage of alkanes by methane [58], hydrogenolysis of polyolefins [59] and alkanes [60], direct transformation of ethylene into propylene [61], etc. These topics are considered in detail in subsequent chapters. 

Zirconium hydride(s) supported on oxide materials catalyze several classical reactions such as hydrogenation, reductive cyclizahon, cyclo-trimerization and olefin polymerization [43-47]. Notably, it also catalyzes the hydrogenolysis of polyolefins...
