“…[ 114 ] This work highlights the ability of MOF‐semiconductor heterojunctions in not only facilitating the electron migration via the NP‐MOF interfaces but also enhancing the CO 2 photocatalytic activity because of the plasmonic resonance stemming from NP‐MOF composites. This work, in addition to many others, also casts light on using the MOF composites, including metal‐transition‐based‐semiconductor/MOFs, [ 115–119 ] quantum‐dot/MOFs, [ 120,121 ] and conjugation‐polymer/MOFs [ 122–125 ] for enhancing the photocatalytic reduction of CO 2 .…”

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

“…Nevertheless, the energy barrier can be effectively reduced by introducing suitable chemical bonding interaction. [ 108,109 ] Wang et al proposed an effective strategy to combine NH 2 ‐UiO‐66 with 3D porous g‐C 3 N 4 (enriched in exposed amino groups) through NH x ZrO chemical bond. [ 108 ] The NH x ZrO chemical bond not only stabilizes the photocatalyst, but also leads to a close contact that can suppress carrier recombination via effect charge transfer.…”

Graphitic carbon nitride as a novel photocatalyst for CO2 reduction reaction (CO2RR) has attracted many recent efforts on the synthesis and modification for improving efficiency and selectivity. Herein, an overview of fundamental factors and the latest research progress of g‐C3N4‐based photocatalysts for CO2RR is provided. The main strategies of fabrication and modification to obtain g‐C3N4 and g‐C3N4‐based composites with high CO2RR efficiency are summarized. Working mechanisms of each enhancement approach in terms of their effects on electronic band structures, light‐harvesting capability, CO2 adsorption capacity, separation of photogenerated electron–hole pairs etc. are explained and discussed. Finally, a brief overview on the challenges and new directions in this field is proposed.

“…[ 8 ] These intrinsic features make MOFs a class of appealing materials for gas separation and storage, sensing, and heterogeneous catalysis. [ 9–16 ] The structural and functional tailorability provides us a promising platform that utilizes the intrinsic properties of organic building block and metal nodes for targeting a diversity of functional MOFs. Usually, the geometry and length of organic building blocks with specific length have much impact on the symmetry and topology of MOFs, while the metal nodes usually play an important role in the chemical stability and functional properties.…”

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.
