Maʻiʻo kumu

Ua paʻi kekahi hui noiʻi mai ka Chinese Academy of Science (CAS) i kā lākou ʻike ma Angewandte Chemie International Edition, e hoʻomohala ana i kahi ʻenehana photocatalytic hou. Ke hoʻohana nei kēia ʻenehana i kahi photocatalyst Pt₁Au/TiO₂ e hiki ai i ka hoʻohui ʻana i ka CN ma waena o ka ethylene glycol (loaʻa mai ka hydrolysis o ka ʻōpala PET plastic) a me ka wai amonia ma lalo o nā kūlana haʻahaʻa, e hoʻopili pololei ana i ka formamide-he mea waiwai nui.

Hāʻawi kēia kaʻina hana i kahi paradigm hou no ka "upcycling" o ka palaka ʻōpala, ma mua o ka hoʻohaʻahaʻa maʻalahi, a ke kaena nei i ka waiwai kaiapuni a me ka waiwai.

Ka hopena o ka ʻoihana

Hāʻawi ia i kahi hopena hoʻohui waiwai kiʻekiʻe hou no ka mālama ʻana i ka pollution plastic, ʻoiai e wehe ana i kahi ala hou no ka synthesis ʻōmaʻomaʻo o nā kemika maikaʻi i loko o ka nitrogen.
