Current Advances of Hollow All-solid-state Z-Scheme Photocatalysts

Hollow structural materials have great application value in photocatalytic applications due to their large specific surface area， low density and short charge transport distance. Z-Scheme photocatalysts have wide range of spectral response， high stability， high separation efficiency of photogenerated carriers， strong oxidation and reduction capabilities， have received widespread attention. However， due to the instability of Z-scheme multi- element structure and hollow structure， it is still a huge challenge to design efficient and stable hollow all-solid-state Z-scheme photocatalysts. In this review， we summarized and discussed the advances progress in the types， construction strategies and performance researches of hollow all-solid-state Z-scheme photocatalysts in recent years， and envisioned the problems and challenges on the future applications， which will provide references for the design of stable photocatalysts.
