“…[ 150 ] At the same time, Lan group reported COFs based on earth‐abundant Ni/Co/Zn active centers metalated using PSM method. [ 151 ] Especially, metal active sites in DQTP COF‐M (DQ = 2,6‐diaminoanthraquinone; TP = 2,4,6‐triformylphloroglucinol; M = Ni, Co, Zn) were intercalated between two layers of the COF through strong coordination bonds of COM (strong interaction); metal active sites in DATP COF‐M (DA = 2,6‐diaminoanthracene) were physically located near the TP moieties (weak interaction). The high charge‐carrier mobility originating from the high π–π interaction of linkers contributed to enhancing the photocatalytic properties of the resultant COFs toward the CO 2 photoreduction.…”

fatally affects the natural greenhouse. Therefore, seeking solutions that ameliorate fossil fuel dependency and CO 2 emission undoubtedly is of urgency. [4] The carbon cycle including selective CO 2 capture, [5] sequestration, [6] and conversion [7] has been used for years to deal with the issues mentioned above. Unlike the capture and sequestration, which have been successfully explored using a variety of porous materials, [8] CO 2 conversion, in which CO 2 is used as C1 starting material for the chemical transformation into other useful feedstocks, is in the early stage of development because there is a lack of effective catalysts and/or optimized conversion processes; therefore, the CO 2 reduction becomes one of the most important but challenging tasks. [9] To cope with this crucial challenge, it is necessary to briefly review the natural photosynthesis, [10] which plants, algae, and/or bacteria capture sunlight and use its photon energy to reduce CO 2 into oxygen (Scheme 1). Notably, in the oxygenic photosynthesis conducted by plants, O 2 and water molecules (six molecules of each) are formed as equivalent as CO 2 input (six molecules). This photosynthesis process not only reintroduces the breathable oxygen but also inspires researchers in imitating the natural photoreduction of CO 2 into clean-burning fuels. The reduction of CO 2 using catalysts activated by sunlight, the universal photon energy from Nature, termed photocatalysis is of great importance for renewable energy. In 1972, Fujishima and Honda discovered the application of TiO 2 as a semiconductor for water hydrolysis under ultraviolet irradiation. [11] This work has influentially underpinned scientists to artificially synthesize many kinds of photocatalytic materials for the transformation of CO 2 under ultraviolet or visible light irradiation, of which the latter is more applicable and important due to its environmental friendly attributes. [12-14] To date, semiconductors commonly used for photocatalysis are TiO 2 , metal alloys, nanowires, quantum dots, graphenebased composites, and to name but a few. [15-17] Among them, porous crystalline materials have been proven to be promising candidates for the CO 2 photoreduction into high value-added chemicals because of their large internal surface area and densely catalytically active sites. [18,19] Particularly, reticular chemistry of metal-organic frameworks (MOFs) possessing endless possibilities to precisely control crystal structures

Photoreduction of CO2 into value‐added fuels is one of the most promising strategies for tackling the energy crisis and mitigating the “greenhouse effect.” Recently, metal–organic frameworks (MOFs) have been widely investigated in the field of CO2 photoreduction owing to their high CO2 uptake and adjustable functional groups. The fundamental factors and state‐of‐the‐art advancements in MOFs for photocatalytic CO2 reduction are summarized from the critical perspectives of light absorption, carrier dynamics, adsorption/activation, and reaction on the surface of photocatalysts, which are the three main critical aspects for CO2 photoreduction and determine the overall photocatalytic efficiency. In view of the merits of porous materials, recent progress of three other types of porous materials are also briefly summarized, namely zeolite‐based, covalent–organic frameworks based (COFs‐based), and porous semiconductor or organic polymer based photocatalysts. The remarkable performance of these porous materials for solar‐driven CO2 reduction systems is highlighted. Finally, challenges and opportunities of porous materials for photocatalytic CO2 reduction are presented, aiming to provide a new viewpoint for improving the overall photocatalytic CO2 reduction efficiency with porous materials.

“…Their study demonstrated that Co dopants not only improved the visible light absorption of TiO 2 but also adjusted the selectivity of the products (CO and CH 4 ) by controlling the molar ratio of Co and Ti hence the amount of V O formed in Co-doped TiO 2 . Lu et al reported a COF composed of 2,6-diaminoanthraquinone-2,4,6-tryiformylphloroglucinol (DQTP) doped with various transition metal ions [53]. The transition metal ion dopants exerted an obvious influence on both reactivity and product selectivity of DQTP COF during the photocatalytic CRR.…”

The excessive use of fossil fuels during rapid industrialization of world has inevitably led to the continuous increase in the atmospheric CO 2 level, which became one of the major concerns worldwide. Using solar energy to convert CO 2 into useful fuels is a promising approach to address both energy shortage and environmental crisis, and this has recently emerged as one of the most important research areas. However, the stable nature of CO 2 molecule under ambient conditions and the complicated reaction mechanism involved in its reduction reaction pose great challenges in both aspects of thermodynamics and kinetics for realizing the practical transformation of CO 2. Nanostructured materials with large surface areas and unique optical and electronic properties are one of core elements in the development of photocatalytic CO 2 conversion platform. In this chapter, a comprehensive understanding on photocatalytic CO 2 reduction, including the reaction mechanism, challenges in both thermodynamic and kinetic aspect, the design principles of a photocatalytic CO 2 reduction system, and the detection methods for various reduction products will be discussed. In addition, recent research developments in high-performance photocatalytic CO 2 conversion systems based on nanomaterials design and their hybrids will be summarized with an outlook on the research trend.
