ʻIke Koʻikoʻi

Ua paʻi kahi hui noiʻi mai ka Chinese Academy of Sciences (CAS) i kā lākou mau ʻike ma Angewandte Chemie International Edition, e hoʻomohala ana i kahi ʻenehana photocatalytic hou. Hoʻohana kēia ʻenehana i kahi photocatalyst Pt₁Au/TiO₂ e hiki ai i kahi hopena hoʻopili CN ma waena o ka ethylene glycol (i loaʻa mai ka hydrolysis o ka ʻōpala PET plastic) a me ka wai ammonia ma lalo o nā kūlana akahai, e hana pololei ana i ka formamide—kahi mea maka kemika waiwai nui.

Hāʻawi kēia kaʻina hana i kahi ʻano hou no ka "upcycling" o ka ʻōpala plastic, ma kahi o ka downcycling maʻalahi, a he waiwai nui ia no ke kaiapuni a me ka hoʻokele waiwai.

Ka Hopena o ka ʻOihana

Hāʻawi ia i kahi hopena waiwai nui hou loa no ka kaohi ʻana i ka haumia plastik, ʻoiai e wehe ana i kahi ala hou no ka synthesis ʻōmaʻomaʻo o nā kemika maikaʻi i loaʻa ka naikokene.
