Core Content
A research team from the Chinese Academy of Sciences (CAS) published their findings in Angewandte Chemie International Edition, developing a new photocatalytic technology. This technology uses a Pt₁Au/TiO₂ photocatalyst to enable a C-N coupling reaction between ethylene glycol (obtained from the hydrolysis of waste PET plastic) and ammonia water under mild conditions, directly synthesizing formamide—a high-value chemical raw material.
This process provides a new paradigm for the “upcycling” of waste plastic, rather than simple downcycling, and boasts both environmental and economic value.
Industry Impact
It offers an entirely new high-value-added solution for plastic pollution control, while also opening up a new path for the green synthesis of nitrogen-containing fine chemicals.
