Photocatalytic technology based on semiconductor materials is expected to use clean solar energy to control the environmental pollution and ease the energy shortages.In recent years, some silver-containing semiconductor materials with narrow band gap exhibit excellent oxidation and reduction ability under visible light irradiation, hence, silver-containing photocatalysts have become one of the focuses in the field of photocatalytic materials. Single silver-containing photocatalytic materials have high cost and poor stability, which limit their practical applications. As a result, the composite photocatalytic materials have been widely studied. Recently, simulating the photosynthesis process of green plants, all-solid-state Z-scheme photocatalytic systems are established, which can enhance the stability and reduce the cost of silver-containing photocatalytic materials as well as improve their photocatalytic performances. In this paper, we firstly describes the derivation and reaction mechanism about the all-solid-state Z-scheme photocatalytic systems, and then reviews the construction, application and reaction mechanism of silver-containing semiconductor materials-based all-solid-state Z-scheme photocatalytic systems so far.At last, we point out some existing problems about these silver-containing semiconductor materials-based Z-scheme photocatalytic systems, and their research prospects are also proposed.
