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 g_cat ⁻¹ h⁻¹, 1.5 times that of bare g-C₃N₄.

在这项工作中，成功地将钌（Ru）单原子装饰在了石墨氮化碳（gC ₃ N ₄）的表面上。通过各种表征，已经证实了Ru单原子的存在和在合成过程中引起的缺陷（氰基）。与没有Ru原子负载的催化剂（Ru-CCN-0）相比，由Ru原子修饰的催化剂（Ru-CCN-0.05）具有更好的吸收能力和更宽的光吸收范围。在没有空穴清除剂的帮助下，Ru-CCN-0.05在超纯水中的光催化固氮速率为2.26 mg L ^-1 g _cat ^-1  h ^-1，是裸露gC ₃ N _4的1.5倍。
