| 英文摘要 | Earth-abundant cobalt oxides as active water oxidation catalysts have attracted extensive attention, but the controlled synthesis of small cobalt oxide clusters still remains challenging. herein we introduce a novel approach to deposit small cobalt oxide clusters on alumina which involves mild oxidation of molecularly dispersed co-4(co)(12) precursor. scanning transmission electron microscope (stem) shows that the size of prepared coox clusters is smaller than 2 nm. turnover frequency (tof) value of water oxidation on the synthesized cobalt oxide clusters can reach as high as 0.067 s(-1) in photochemical ru(bpy)(3)(2+)-na2s2o8 system, which is at least an order of magnitude higher than bulk cobalt oxide nanoparticles. the remarkably enhanced activity of cobalt oxide cluster is attributed to its more surface-exposed cobalt atoms and higher intrinsic activity.
