Abstract Carbon dots (CDs) have rapidly emerged as a new family of carbon‐based nanomaterials since their initial discovery two decades ago. Numerous appealing properties, such precursor and synthesis process flexibility, tunable photoluminescence, good biocompatibility, enabled widespread applications in sensing, catalysis, energy, biomedical fields. As the field expands, notable efforts recently focused on mechanistically elucidating structural formation optical behavior CDs. However, absence “clean” CDs presents major obstacle to achieving solid understanding these aspects. Often, claimed are, fact, mixture small molecules, oligomers, nano‐sized aggregates, or even microparticles. Such coexistence impurities markedly impacts physicochemical properties resulting CD‐based mixtures, hampering resolution key mechanistic questions. Here, we aim address this fundamental shortcoming field, going beyond customary focus existing reviews that predominantly cover synthesis, performance, application prospects. We begin with an overview CD then thoroughly examine purification methods, including filtration, dialysis, electrophoresis, chromatography. The insights provided here will guide researchers towards obtaining high‐quality CDs, employing proper combinations available tools, ultimately paving way for more demanding applications.

The chemical structure and photoredox properties of carbon dots (CDs) are not yet fully understood. However, it has been reported that, by carefully choosing the starting materials tuning their synthesis conditions, is possible to obtain CDs with different structures therefore photocatalytic performance. For this work, a family was synthesized in Milli-Q water via microwave-assisted protocol, using citric acid urea as precursors. syntheses were carried out at times temperatures assess impact synthetic parameters on final materials. After extensive accurate purification, abilities selected subset tested performing photocatalyzed atom transfer radical addition reaction. Among CDs, best ones found be those highest temperature, which most graphitic. A number characterization techniques then used evaluate degree graphitization elucidate origin
