Solar‐driven water splitting is a promising way to produce renewable hydrogen. The design of efficient semiconductor photocatalysts plays a vital role in this process. The recent dynamic development of metal–organic framework (MOF) materials provides a good opportunity to design efficient composite photocatalysts toward solar water splitting. Herein, a critical review of the design and development of MOF/semiconductor composite photocatalysts for solar‐driven water splitting is presented. The designing strategies of MOF‐based composite photocatalysts, including the use of organic ligands, quantum dots and carbon‐based materials to form heterostructures, and the combination of MOF layers with semiconductors to fabricate thin‐film photoelectrodes for photoelectrochemical water splitting, are introduced. The remaining challenges and future perspectives of the MOF‐based composites with the hope of achieving improved solar water splitting are also discussed.

“…Recently, Han et al obtained a range of TiO 2 @NH 2 -MIL-125(Ti) heterostructures with different degrees of exposed active crystal planes by adding a directional chemical protective agent to insitu hydrolyze and etch NH 2 -MIL-125(Ti) from inside to outside (Fig. 9) [64]. The morphology of heterostructures changed from core-shell, hollow to frame with increasing hydrolysis time.…”

“…Since the metal organic frameworks (MOFs) were synthesized in the 1990s, they have been widely used in adsorption, separation, catalysis, energy storage, pharmaceutical, and other fields due to their large specific surface area, porosity, convenient synthesis, good thermal stability, variable skeleton size, and chemical modification (Ren et al, 2018 ; Sun et al, 2020a , b ). Selecting the precursors and calcination conditions of MOFs is an effective strategy to prepare new carbon nanomaterials with controllable size, shape, and composition.…”

“…Recently, carbon-based nanomaterials have been widely developed and been used in many fields such as energy storage and conversion, photocatalysis, electrocatalysis, gas, and water treatment systems and biomedicine (Liu et al, 2017a(Liu et al, ,b, 2018Yang et al, 2018;Liu Y.

Among various carbon nanomaterials, hollow carbon nanostructures (HCNs) (Figure 1) have attracted considerable interests due to their high thermal stability, strong electron transport ability, large specific surface area, plentiful exposed active sites, and flexible shape and structure (Wen et al, 2007;Guo et al, 2019;Chen et al, 2020;Gao et al, 2020;Wang et al, 2020;Yuan et al, 2020b). A large number of studies have shown that HCNs exhibit excellent performance for energy, catalysis, electronics, biomedical, and so on in terms of their unique hollow structures.…”

Carbon nanomaterials with high electrical conductivity, good chemical, and mechanical stability have attracted increasing attentions and shown wide applications in recent years. In particularly, hollow carbon nanomaterials, which possess ultrahigh specific surface area, large surface-to-volume ratios, and controllable pore size distribution, will benefit to provide abundant active sites, and mass loading vacancy, accelerate electron/ion transfer as well as contribute to the specific density of energy storage systems. In this mini-review, we summarize the recent progresses of hollow carbon nanomaterials by focusing on the synthesis approaches and corresponding nanostructures, including template-free and hard-template carbon hollow structures, metal organic framework-based hollow carbon structures, bowl-like and cage-like structures, as well as hollow fibers. The design and synthesis strategies of these hollow carbon nanomaterials have been systematically discussed. Finally, the emerging challenges and future prospective for developing advanced hollow carbon structures were outlined.
