Likenyelletso
Li-catalyst tsa tšepe ea bohlokoa ke litšepe tse ntle tse sebelisoang haholo indastering ea lik'hemik'hale ka lebaka la bokhoni ba tsona ba ho potlakisa ts'ebetso ea lik'hemik'hale. Khauta, palladium, platinum, rhodium le silevera ke tse ling tsa mehlala ea litšepe tsa bohlokoa. Li-catalyst tsa tšepe ea bohlokoa ke tse nang le likaroloana tsa tšepe ea bohlokoa tse hasaneng haholo tse tšehelitsoeng sebakeng se phahameng joalo ka khabone, silica le alumina. Li-catalyst tsena li na le lits'ebetso tse 'maloa liindastering tse fapaneng. Catalyst e 'ngoe le e 'ngoe ea tšepe ea bohlokoa e na le litšobotsi tse ikhethang. Li-catalyst tsena li sebelisoa haholo bakeng sa likarabelo tsa tlhahiso ea lintho tse phelang. Lintlha tse kang tlhoko e ntseng e hola ho tsoa makaleng a tšebeliso ea ho qetela, matšoenyeho a tikoloho le litlamorao tsa tsona tsa molao li khanna kholo ea' maraka.

1. Mosebetsi o phahameng le khetho e phahameng ea litšepe tsa bohlokoa ho catalysis
Li-catalyst tsa tšepe ea bohlokoa li entsoe ka likaroloana tsa tšepe ea bohlokoa tse hasaneng haholo tse tšehetsang tse nang le sebaka se phahameng joalo ka khabone, silica le alumina. Likaroloana tsa tšepe ea nanoscale li monya haeterojene le oksijene habonolo sepakapakeng. Haeterojene kapa oksijene e sebetsa haholo ka lebaka la ho monya ha eona ka li-dissociative adsorption ka d-electron ea liathomo tsa tšepe ea bohlokoa.
2.Botsitso
Tšepe tsa bohlokoa li tsitsitse. Ha li etse li-oxide habonolo ka oxidation. Li-oxide tsa tšepe tsa bohlokoa, ka lehlakoreng le leng, ha li tsitsitse. Tšepe tsa bohlokoa ha li qhibilihe habonolo ka har'a tharollo ea asiti kapa alkaline. Ka lebaka la botsitso bo phahameng ba mocheso, catalyst ea tšepe ea bohlokoa e 'nile ea sebelisoa e le catalyst ea tlhoekiso ea khase ea mosi oa likoloi.
