“…Due to the poison of surface reactive sites, the activity of common catalysts degrades with increasing reaction time. [36,37] To date, most catalytic systems for the photoreduction of CO 2 can only operate steadily over periods of several to several tens of h, [4][5][6] and only few catalysts reach around 100 h stability, [16,38] significantly impeding the commercialization of existing catalysts. Herein, the long-term stability of the catalyst was evaluated by comparing NMR, UV/ Vis absorption, and Fourier-transform infrared (FTIR) spectra (Figure S9) of the fresh and the used DTBT-C 60 .…”

Conversion of CO2 into carbonaceous fuels with the aid of solar energy has been an important research subject for decades. Owing to their excellent electron‐accepting capacities, fullerene derivatives have been extensively used as n‐type semiconductors. This work reports that the fulleropyrrolidine functionalized with 4,7‐di(thiophen‐2‐yl)benzo[c][1,2,5]thiadiazole, abbreviated as DTBT‐C60, could efficiently catalyze the photoreduction of CO2 to CO. The novel C60‐chromophore dyad structure facilitated better usage of solar light and effective dissociation of excitons. Consequently, the DTBT‐C60 exhibited a promising CO yield of 144 μmol gcat−1 under AM1.5G solar illumination for 24 h. Moreover, the isotope experiments demonstrated that water molecules could function as an electron source to reactivate DTBT‐C60. Impressively, DTBT‐C60 exhibited an extremely durable catalytic activity for more than one week, facilitating the practical application of photochemical CO2 reaction.

“…MOFs are a new type of porous material with metal ions or clusters coordinated with organic ligands. Due to their high porosity, large specific surface area and flexible structure, MOFs have been applied in electrocatalytic research recently [43,132]. However, some disadvantages, such as poor conductivity and less active centers, hamper their electrocatalytic activity.…”

“…Therefore, 2D structures can promote the chemisorption of reactants and improve catalytic performance. A large class of 2D materials, such as noble metals, metal oxides, graphene, graphite carbon nitride (g-C 3 N 4 ), transition metal dichalcogenides (TMDs), metal-organic frameworks (MOFs), etc., has been demonstrated to have great potential to catalyze CO 2 conversion reactions [38][39][40][41][42][43]. Particularly, graphene, known as the first invented 2D material, has attracted extensive attention for many applications [44].…”

Electrocatalytic CO2 reduction (ECR) is an attractive approach to convert atmospheric CO2 to value-added chemicals and fuels. However, this process is still hindered by sluggish CO2 reaction kinetics and the lack of efficient electrocatalysts. Therefore, new strategies for electrocatalyst design should be developed to solve these problems. Two-dimensional (2D) materials possess great potential in ECR because of their unique electronic and structural properties, excellent electrical conductivity, high atomic utilization and high specific surface area. In this review, we summarize the recent progress on 2D electrocatalysts applied in ECR. We first give a brief description of ECR fundamentals and then discuss in detail the development of different types of 2D electrocatalysts for ECR, including metal, graphene-based materials, transition metal dichalcogenides (TMDs), metal–organic frameworks (MOFs), metal oxide nanosheets and 2D materials incorporated with single atoms as single-atom catalysts (SACs). Metals, such as Ag, Cu, Au, Pt and Pd, graphene-based materials, metal-doped nitric carbide, TMDs and MOFs can mostly only produce CO with a Faradic efficiencies (FE) of 80~90%. Particularly, SACs can exhibit FEs of CO higher than 90%. Metal oxides and graphene-based materials can produce HCOOH, but the FEs are generally lower than that of CO. Only Cu-based materials can produce high carbon products such as C2H4 but they have low product selectivity. It was proposed that the design and synthesis of novel 2D materials for ECR should be based on thorough understanding of the reaction mechanism through combined theoretical prediction with experimental study, especially in situ characterization techniques. The gap between laboratory synthesis and large-scale production of 2D materials also needs to be closed for commercial applications.

“…[25,26] However, these reviews could not fully cover the representative research achievements of titanium-based MOF from crystal engineering to photocatalysis in the recent years, especially the latest several years, at which time both the structures and photocatalytic applications of Ti-MOFs had made a significant progress. [27,28] Recently, a review about Ti-MOFs and their derived materials for photocatalysis had been reported. [29] This review article focuses on the titanium-based MOFs composites and derived TiO 2 materials for photocatalytic reaction of H 2 production, remediation of organic and inorganic pollutants, and organic transformation reaction.…”

Titanium‐Based MOF Materials: From Crystal Engineering to Photocatalysis

Titanium (Ti)‐based metal–organic frameworks (MOFs) have attracted intensive attention due to the low toxicity, high earth's crust abundance, and unique photocatalytic properties of Ti elements. Great efforts have been devoted to the synthesis of novel architectures and their potential applications involving photocatalysis. However, Ti‐MOFs are still very scarce owing to their challenges in controlling the Ti chemistry in the reaction system. Until now, some significant results have been achieved, which may shed new insight into the future investigation of Ti‐MOFs. Herein, some representative researches in Ti‐MOFs are summarized and reviewed from the following four aspects: first, various synthetic strategies for preparing Ti‐MOFs are introduced; second, diverse structures containing multi‐connected ligands are presented in detail; third, the potential photocatalytic applications of Ti‐based MOFs involving H2 production, CO2 reduction, H2O2 production, N2 fixation, remediation of organic and inorganic pollutants, as well as organic transformation reaction and photocatalytic sensors are discussed; finally, perspectives on current challenges and emerging opportunities in this research field are discussed. Through summarizing this specific type of MOF, this review is expected to stimulate researchers’ interest for in‐depth investigation of novel structures synthesis, as well as new applications and concepts in these intriguing fields.
