A novel kind of highly efficient photocatalyst composed of ultrathin P‐doped ZnO nanosheets decorated with atomic MoS2 layers is reported. Under natural sunlight, 95 % of the organic dyes can be degraded within six minutes. The photodegradation rate constant reaches up to 1.413 min −1 , which is 3.4 times larger than that of commercial P25 under the same reaction conditions. The superior photocatalytic activity of the hybrid photocatalyst can be attributed to the synergetic effects of many advantages, including enhanced light adsorption efficiency, suppression of charge recombination, improvement of interfacial charge transfer, and an increase in the number of reaction sites.
