production, especially for hydroelectricity, sunlight, and wind energy, which cannot be gathered or released when they are needed. [5][6][7][8] Electrochemical energy storage devices provide a promising approach for the storage of electric energy from these sources. [9][10][11] Currently, carbonaceous materials have attracted much interest for their extensive applications including adsorption, [12] catalysis, [13] batteries, [14] fuel cells, [15,16] supercapacitors, [17,18] and drug delivery and imaging. [19] In addition, some sensors are also one of the important applications of carbonaceous materials, because they are closely related to human health. [20,21] For instance, Emran and co-workers [22] constructed ultrasensitive biosensors with N-doped mesoporous carbon (NMC)-based electrodes for in vitro monitoring of DA released from living cells. With the further study of the experiment, they also designed a series of S-doped carbon materials for a wider detection of DA, UA (uric acid), and AA (ascorbic acid). [23,24] The advantages of easy preparing, nontoxic and excellent electrical conductivity of carbonaceous materials, which are rare among energy storage materials, make carbonaceous materials superior to most of the energy storage materials. [25][26][27] There are varieties of approaches for the preparation of carbon materials, such as directly carbonizing from organic precursors, physically or chemically carbonizing from carbon, template methods using zeolites and mesoporous silica, solvothermal and hydrothermal methods with elevated temperature, the electrical arc methods, and chemical vapor decomposition (CVD) methods. [28][29][30][31][32][33][34] Among all these approaches, directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons (NPCs) due to its flexibility and simplicity. [35][36][37] However, these NPC materials present certain drawbacks, such as low surface areas, disordered structures, and ununiformed sizes, which will greatly limit their applications. [25] As studies have progressed, researchers found that carbon materials derived from metalorganic frameworks (MOFs) could overcome these limitations.Metal-organic frameworks, which are also named porous coordination polymers (PCPs), are crystalline porous materials with periodic network structures formed by metal ions (or metal clusters) and organic ligands. [38][39][40][41][42] They are usually prepared by solvothermal methods and used as precursors or templates to form nanostructured materials. [43][44][45] So far, many researchers have highlighted the advantages of MOFs. For Carbon materials derived from metal-organic frameworks (MOFs) have attracted much attention in the field of scientific research in recent years because of their advantages of excellent electron conductivity, high porosity, and diverse applications. Tremendous efforts are devoted to improving their chemical and physical properties, including optimizing the morphology and structure of the carbon materials, compositing them wi...

“…Therefore, the suitable combination of Co and Te [321] on a MOF module would improve the photocatalytic performance of the material not only by increasing conductivity in a minimized manner of charge recombination but also by requiring little free energy for the formation of intermediate substrates in the reduction process.…”

The accumulation of carbon dioxide (CO2) pollutants in the atmosphere begets global warming, forcing us to face tangible catastrophes worldwide. Environmental affability, affordability, and efficient CO2 metamorphotic capacity are critical factors for photocatalysts; metal-organic frameworks (MOFs) are one of the best candidates. MOFs, as hybrid organic ligand and inorganic nodal metal with tailorable morphological texture and adaptable electronic structure, are contemporary artificial photocatalysts. The semiconducting nature and porous topology of MOFs, respectively, assists with photogenerated multi-exciton injection and adsorption of substrate proximate to void cavities, thereby converting CO2. The vitality of the employment of MOFs in CO2 photolytic reaction has emerged from the fact that they are not only an inherently eco-friendly weapon for pollutant extermination, but also a potential tool for alleviating foreseeable fuel crises. The excellent synergistic interaction between the central metal and organic linker allows decisive implementation for the design, integration, and application of the catalytic bundle. In this review, we presented recent MOF headway focusing on reports of the last three years, exhaustively categorized based on central metal-type, and novel discussion, from material preparation to photocatalytic, simulated performance recordings of respective as-synthesized materials. The selective CO2 reduction capacities into syngas or formate of standalone or composite MOFs with definite photocatalytic reaction conditions was considered and compared.
