Many porous organic polymers (POPs) possess excellent light absorption capacity and CO2 absorption performance owing to their conjugated skeletons and large specific surface area values. Some of these fascinating materials have inherent reaction sites for CO2 conversion and appropriate band structures to catalyze the CO2 reduction reaction. Therefore, these POPs have been used as heterogeneous catalysts in the photocatalytic CO2 reduction reaction. Among those POPs, four kinds of catalytic systems have been developed for realizing the CO2 photoreduction reaction: POPs loaded with noble metals, POPs loaded with non‐noble metals, POPs combined with inorganic semiconductors, and metal‐free POPs. Each of these catalytic systems has its own advantages and drawbacks. In general, the catalytic system of supported metals has higher catalytic efficiency but lower durability than metal‐free POPs. It should be noted that in the process of catalyst development, the co‐catalyst is gradually minimizing in POPs to achieve a more green CO2 photoreduction reaction. In this review, different types of POPs and the relationship between their structures and catalytic performance in the photocatalytic reduction of CO2 are summarized.

“…Photocatalysis is one of the most clean and promising approaches to transform solar energy to available chemical energy through formations of chemical bonds in molecules. [1][2][3][4] Semiconducting materials have been widely used as photocatalysts for the production of value-added chemicals through the direct conversion of solar energy. To do so, a variety of photocatalysts such as organic/inorganic composites, 5,6 quantum dots, 7,8 and expensive transition metal complexes [9][10][11][12] have been developed for the wide photocatalytic applications.…”

Direct conversion of sunlight into value-added chemicals through artificial photosynthesis has been recognized as one of the most promising ways to address the global energy needs and to utilize the sustainable energy source. Even though the various semiconducting materials have been used for the solardriven production of chemicals, many experimental efforts have been still focusing on developing clean and reusable photocatalysts. In this study, we report the new metal-free graphitic carbon nitride (g-C 3 N 4 ) composite including anthracene moieties as a primary photosensitizer. The morphological and electronic structure of anthracene-based g-C 3 N 4 (An-g-C 3 N 4 ) composite were characterized by optical spectroscopies, electrochemical measurements, and theoretical calculations based on density-functional theory. The An-g-C 3 N 4 composite exhibited outstanding photocatalytic efficiency for the regenerations of NAD(P)H cofactors owing to the prominent charge-transferred character and the superb light absorption. This study demonstrates that the catalytic reaction employing the combination of An-g-C 3 N 4 photocatalyst and Z-scheme nature would be a suitable option for artificial photosynthesis.

Two‐Dimensional Covalent‐Organic Frameworks for Photocatalysis: The Critical Roles of Building Block and Linkage

et al. 2020

View full text Add to dashboard Cite

Covalent organic frameworks (COFs) are a class of crystalline porous materials which contain organic build blocks linked via covalent bonds to form ordered and periodic structures. In recent years, 2D COFs have been developed as promising heterogeneous photocatalysts due to their extended π‐conjugated skeletons, high surface area, tunable structure, regular pore structure, and high crystallinity. Herein, recent advances in the design and synthesis of 2D COFs for photocatalysts are surveyed, the illustration of the structural features and synthetic strategy is focused on, and the relationship between the construction and property of 2D COFs for photocatalytic water splitting, CO2 reduction, organic transformation, and degradation of organic pollutants is elucidated. This overview is expected to provide clues to rational design and synthesis of ultra‐stable, high crystalline, and high‐performance 2D COFs for photocatalytic applications.
