Researchers report green synthesis of graphene for targeted recovery of silver from photovoltaic waste
In 2015, scientists at James Cook University in Queensland, Australia, and collaborators from institutions in Australia, Singapore, Japan, and the US developed a technique for growing graphene from tea tree extract. Now, scientists from James Cook University developed a process to synthesize graphene from tangerine peel oil, which they then used to recover silver from waste PV material. To demonstrate the quality of the recovered silver and the synthesized graphene, they made a dopamine sensor that reportedly outperformed reference devices.
The team synthesized “freestanding” graphene using non-toxic and renewable tangerine peel oil that can reportedly be used for the recovery of silver from end-of-life organic PV devices. The researchers said that their process result in high-quality graphene and demonstrated a remarkable ability to selectively recover silver from photovoltaic waste. One of the most surprising findings, according to the team, was how selective the graphene was in targeting silver.
