摘要：

Core/shell-structured nanodiamonds exhibit excellent adsorption and photocatalytic properties by annealing in an Ar atmosphere. Results show that core/shell-structured nanodiamond/onion-like carbon materials are obtained at high-temperature annealing (1400 degrees C-1500 degrees C) and possess a favorable visible light photocatalytic activity. Solutions with 10 and 100 mg L-1 methyl orange can be nearly degraded completely within 30 min and 1 h, respectively, using nanodiamonds annealed at 1500 degrees C.
