Mar as trice, thathas a’ riochdachadh catalyst Adams, ris an canar cuideachd platanam dà-ogsaid, mar hydrate ogsaid platanam(IV), PtO2•H2O. ’S e catalyst a th’ ann airson hydrogenation agus hydrogenolysis ann an co-chur organach. Tha am pùdar donn dorcha seo ri fhaighinn gu malairteach. Chan e catalyst gnìomhach a th’ anns an ogsaid fhèin, ach bidh e gnìomhach às dèidh dha a bhith fosgailte do haidridean agus an uairsin bidh e ag atharrachadh gu platanam dubh, a tha an urra ri ath-bheachdan.
1. Catalaiche hydrogenation, freagarrach airson ceangal dùbailte, ceangal trì-fhillte, hydrocarbon aramatach, carbonyl, nitrile, lughdachadh nitro.
2.Stuthan sàr-mhath airson gabhail a-steach haidridean.
3. Resistance le raon luach strì ìosal ann an gnìomhachas dealanach.
4. Stuthan amh airson co-phàirtean leithid potentiometer agus stuthan loidhne film thiugh airson gnìomhachas dealanach.
