Selective deposition of plasmonic copper on few layers graphene with specific defects for efficiently synchronous photocatalytic hydrogen production

Graphene from chitosan (CG) with wrinkle, few layers and specific defects was prepared via a simple method of low carbonization temperature and high KOH activation temperature. At the activation temperature of 1100 °C, the obtained CG-1100 has the specific surface of 1212 m2·g−1 and the total volume of 1.02 cm3·g−1 at the optimized activation temperature. The results show that the CG-1100 is similar to another two graphenes: graphene...
