Seeking clean energy as an alternative to traditional fossil fuels is the inevitable choice to realize the sustainable development of the society. Photocatalytic technique is considered a promising energy conversion approach to store the abundant solar energy into other wieldy energy carriers like chemical energy. Carbon dots, as a class of fascinating carbon nanomaterials, have already become the hotspots in numerous photoelectric researching fields and particularly drawn keen interests as metal-free photocatalysts owing to strong UV-vis optical absorption, tunable energy-level configuration, superior charge transfer ability, excellent physicochemical stability, facile fabrication, low toxicity, and high solubility. In this review, the classification, microstructures, general synthetic methods, optical and photoelectrical properties of carbon dots are systematically summarized. In addition, recent advances of carbon dots based photoinduced reactions including photodegradation, photocatalytic hydrogen generation, CO 2 conversion, N 2 fixation, and photochemical synthesis are highlighted in detail, deep insights into the roles of carbon dots in various systems combining with the photocatalytic mechanisms are provided. Finally, several critical issues remaining in photocatalysis field are also proposed.

Carbon dots (CDs), fluorescent carbon nanoparticles with particle sizes < 10 nm, are constantly being developed for potential large‐scale applications. Recently, methods allow CD synthesis to be carried out on large‐scale preparation in a controlled fashion are potentially important for multiple disciplines, including bottom‐up strategy, top‐down method. In this review, the recent progresses in the research of the methods for large‐scale production of CDs and their functionalization are summarized. Especially, the methods of CD synthesis, such as large‐scale preparation, hydrothermal/solvothermal, microwave‐assisted, magnetic hyperthermia microfluidic and other methods, along with functionalization of CDs, are summarized in detail. By promising applications of CDs, there are three aspects have been already reported, such as enhancing mechanical properties, flame retardancy, and energy storage. Also, future development of CDs is prospected.

“…Then, the generated activator Cu I /L reacts with a C(sp 3 )–X polymer chain end to form a carbon radical and the X–Cu II /L deactivator. Oxygen tolerance in this approach can be achieved using an excess ligand. − However, photoinduced Cu-catalyzed ATRP typically requires the use of biocidal UV light. ,, In organocatalyzed ATRP (O-ATRP), the dormant polymer chain is directly activated by electron transfer from a photoredox catalyst (PC) in the excited state (Figure b). − O-ATRP is compatible with a wide range of visible light but is mainly limited to methacrylates and organic solvents. − ATRP with dual catalysis uses copper complexes to attain a controlled radical propagation and PCs to trigger and drive polymerization (Figure c). ,− The photoredox/copper dual catalysis overcomes the challenges of using biocidal UV light, poor oxygen tolerance, and limited monomer scope.…”

Fully Oxygen-Tolerant Visible-Light-Induced ATRP of Acrylates in Water: Toward Synthesis of Protein-Polymer Hybrids

Over the last decade, photoinduced ATRP techniques have been developed to harness the energy of light to generate radicals. Most of these methods require the use of UV light to initiate polymerization. However, UV light has several disadvantages: it can degrade proteins, damage DNA, cause undesirable side reactions, and has low penetration depth in reaction media. Recently, we demonstrated green-light-induced ATRP with dual catalysis, where eosin Y (EYH 2 ) was used as an organic photoredox catalyst in conjunction with a copper complex. This dual catalysis proved to be highly efficient, allowing rapid and well-controlled aqueous polymerization of oligo(ethylene oxide) methyl ether methacrylate without the need for deoxygenation. Herein, we expanded this system to synthesize polyacrylates under biologically relevant conditions using Cu II /Me 6 TREN (Me 6 TREN = tris[2-(dimethylamino)ethyl]amine) and EYH 2 at ppm levels. Water-soluble oligo(ethylene oxide) methyl ether acrylate (average M n = 480, OEOA 480 ) was polymerized in open reaction vessels under green light irradiation (520 nm). Despite continuous oxygen diffusion, high monomer conversions were achieved within 40 min, yielding polymers with narrow molecular weight distributions (1.17 ≤ D̵ ≤ 1.23) for a wide targeted DP range (50−800). In situ chain extension and block copolymerization confirmed the preserved chain end functionality. In addition, polymerization was triggered/halted by turning on/off a green light, showing temporal control. The optimized conditions also enabled controlled polymerization of various hydrophilic acrylate monomers, such as 2-hydroxyethyl acrylate, 2-(methylsulfinyl)ethyl acrylate), and zwitterionic carboxy betaine acrylate. Notably, the method allowed the synthesis of well-defined acrylate-based protein-polymer hybrids using a straightforward reaction setup without rigorous deoxygenation.
