【 摘 要 】

Ruthenium (Ru) single atoms were decorated on the surface of the graphitic carbon nitride (g-C3N4) successfully in this work. By varieties of characterization, the existence of Ru single atoms and the defects (cyano groups) caused in the process of synthesis have been confirmed. The catalyst decorated by Ru atoms (Ru-CCN-0.05) had better absorption capacity and a wider absorption range of light than the catalyst with no Ru atoms loading on (Ru-CCN-0). Without the help of hole-scavengers, the rate of photocatalytic nitrogen fixation of Ru-CCN-0.05 in ultra-pure water was 2.26 mg L−1 gcat −1 h−1, 1.5 times that of bare g-C3N4.
