英文摘要	Pristine graphitic carbon nitride g-c3n4 materials, as a novel metal-free photocatalyst with moderate activity, have attracted intense interest. however, its fast photogenerated carriers recombination always induces a relative low performance. herein, we for the first time report one new =c=o group linked g-c3n4 (co-c3n4) through co2-assisted thermal polymerization of urea. it is found that the edge =c=o groups work as the photogenerated electrons collection sites and then promote the carriers separation. the visible-light photo-tatalytic hydrogen evolution performance of our synthesized samples shows 1.85 times higher than that of the reference g-c3n4. to get a considerable visible-light driven photocatalytic hydrogen generation, a new few layered mos2 with a small size (ca. 20 nm) is prepared through a liquid exfoliation and then is loaded onto the co-c3n4. the optimal mos2/co-c3n4 sample gives the photocatalytic hydrogen evolution of 1990 and 1440 mu mol/(g*h) under the lambda > 400 and 420 illumination, higher than the reported values in the literature. the sample also shows a considerable excellent photocatalytic activity of 44.3 mu mol/(g*h) under led-600 condition.
