“…Cyclic Voltammetry (CV) experiments were carried out on a-N-CDs in our previous work [ 42 ] to measure their redox activity and correlate the energy levels of the nanomaterials with the relative band gap. a-N-CDs showed a negative potential (E onset red = −1.94 vs Ag|AgCl), suggesting a good reducing capability.…”

The synthesis, characterization and photoreduction ability of a new class of carbon dots made from fish scales is here described. Fish scales are a waste material that contains mainly chitin, one of the most abundant natural biopolymers, and collagen. These components make the scales rich, not only in carbon, hydrogen and oxygen, but also in nitrogen. These self-nitrogen-doped carbonaceous nanostructured photocatalyst were synthesized from fish scales by a hydrothermal method in the absence of any other reagents. The morphology, structure and optical properties of these materials were investigated. Their photocatalytic activity was compared with the one of conventional nitrogen-doped carbon dots made from citric acid and diethylenetriamine in the photoreduction reaction of methyl viologen.

“…The CDs were then employed as photosensitizers in an organic reaction, demonstrating excellent performance depending on their structure and synthetic pathway. 154,155 Zhu et al fabricated nitrogen-doped citric acid derived CDs by a hydrothermal method. Citric acid and ethylenediamine were dissolved in deionized-water and heated at 200 °C for 5 h in a Teflon-lined autoclave.…”

“…As a new member of the carbon‐based material, CDs are considered to be a promising material in the field of energy storage and conversion systems due to the abundant surface functional groups, good biocompatibility, high aqueous solubility, as well as low cost. [ 236,237 ] Owing to its exceptional electron transfer ability, a few researchers have utilized the CDs as a co‐catalyst to prepare high‐performance CDs/MOFs photocatalysts. [ 238,239 ]…”

Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due to their unique morphology, high photocatalytic performance, good chemical stability, easy synthesis, and low cost. In this review, the synthetic strategies of developing MOFs‐based photocatalysts are first introduced. Second, the recent progress in the fabrication of various types of MOFs composites photocatalysts is summarized. Third, the different applications including hydrogen evolution reaction, oxygen evolution reaction, overall water splitting, nitrogen reduction reaction, carbon dioxide reduction reaction as well as photodegradation of organic pollutants of MOFs‐based photocatalysts are summed up. Finally, the challenges and some suggestions for the future development of MOFs‐ and their composites‐based photocatalysts are also highlighted. It is expected that this report will help researchers to systematically devise and develop highly efficient photocatalysts based on MOFs and their composites.

Carbon dots as photocatalysts for organic synthesis: metal-free methylene–oxygen-bond photocleavage

Abstract: We report for the first time that irradiation of four different citric acid-derived carbon dots (CDs), in the absence of any other redox mediators, promotes an organic reaction.
