Generally, the low electron–hole separation efficiency of covalent organic frameworks (COFs) prevents their catalytic performance from reaching satisfactory results. For this reason, the creation of heterojunctions is considered an effective strategy but usually suffers from dimensional mismatch of the integrated material, even at the expense of its redox capacity. To overcome these difficulties, a novel 2D/2D S‐scheme heterojunction between H2N–Cu–MOF (NCM) and TpPa–1–COF (TP1C) is successfully constructed for efficient photocatalytic H2 production. The matching dimensions of two crystalline porous materials enables the integrated materials with abundant surface reactive sites, strong interaction and optimized electronic structure. Moreover, the combination of two crystalline porous materials can also form a S–scheme heterojunction, which can not only promote the separation of electron–hole pair, but also preserve the redox ability, thus remarkably boosting the catalytic competence. Consequently, the rate of optimal 20% NCM/TP1C in photocatalytic H2 production reaches 4.19 mmol g−1 h−1, which is 46.5 times higher than that of bare NCM, and 22.1 folds over that of pure TP1C. This research offers an innovative perspective for the formation of S–scheme heterojunctions based on porous crystal materials for efficient solar energy utilization.

Metal-organic frameworks (MOFs) materials have become a research forefront in the field of photocatalytic CO 2 reduction attributed to their ultra-high specific surface area, adjustable structure, and abundant catalytic active sites. Particularly, MOFs can be facilely tuned to match CO 2 photoreduction by utilizing post-modification of metal nodes, functionalization of organic linkers, and combination with other active materials. Herein, the recent advances in the construction strategy of MOF-based photocatalysts materials for CO 2 reduction are highlighted. Some systematic modification strategies on MOF-based photocatalysts are also discussed, such as modification of metal sites and organic ligands, construction of heterojunction, introduction of single/dual-atom, and strain engineering. Finally, the future development directions of MOF-based photocatalysts in the field of CO 2 reduction are presented.

“…5,[9][10][11] Among them, metal-organic frameworks (MOFs) have achieved remarkable achievements in catalyzing the conversion of CO 2 for high-performance cathodes. [12][13][14][15][16][17] However, the bulky nature of MOFs impedes the further enhancement of catalytic performance by reason of limited exposure of catalytic surface. [18][19][20] In this regard at least, lowering the size of bulky MOFs into two-dimensional (2D) metal-organic layers (MOLs) holds great promise for boosting CO 2 reduction/evolution kinetics due to their well exposed catalytically active sites and inherited structural advantages.…”
