Biomass resources are often disposed of inefficiently and it causes environmental degradation. These wastes can be turned into bio‐products using effective conversion techniques. The synthesis of high‐value bio‐products from biomass adheres to the principles of a sustainable circular economy in a variety of industries, including agriculture. Recently, fluorescent carbon dots (C‐dots) derived from biowastes have emerged as a breakthrough in the field, showcasing outstanding fluorescence properties and biocompatibility. The C‐dots exhibit unique quantum confinement properties due to their small size, contributing to their exceptional fluorescence. The significance of their fluorescent properties lies in their versatile applications, particularly in bio‐imaging and energy devices. Their rapid and straight‐forward production using green/chemical precursors has further accelerated their adoption in diverse applications. The use of green precursors for C‐dot not only addresses the biomass disposal issue through a scientific approach, but also establishes a path for a circular economy. This approach not only minimizes biowaste, which also harnesses the potential of fluorescent C‐dots to contribute to sustainable practices in agriculture. This review explores recent developments and challenges in synthesizing high‐quality C‐dots from agro‐residues, shedding light on their crucial role in advancing technologies for a cleaner and more sustainable future.

“…Carbon dots have also been shown to have applications in the realm of both photocatalysis and bioimaging [19][20][21][22], and even in anti-counterfeit printing [23]. In addition, the tunable excitation and emission behavior of carbon dots provides different colors or even white light, which is of great importance for energy applications [24,25].…”

This article investigates the environmentally friendly synthesis and characterization of carbon dots (CDs) derived from soybean biomass, in conjunction with their composites containing potassium chloride (KCl) or zeolite. By using an environmentally sustainable synthetic approach, this study sought to unlock the potential of these materials for various applications. The physicochemical properties of the CDs and composites were comprehensively analyzed using various techniques including scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction analysis. In addition, various optical properties such as UV–Vis absorption, band gap, and excitation–emission behavior were investigated. A key finding to arise from this study was that the inclusion of a doping agent such as KCl or zeolite significantly reduced the size of the resulting CDs. In this light, whereas the undoped species are associated with average sizes of 8.86 ± 0.10 nm, those doped with either zeolite or KCl were associated with average sizes of 3.09 ± 0.05 and 2.07 ± 0.05 nm, respectively. In addition, it was shown that doping with either zeolite or KCl resulted in an alteration of the elemental composition of the CDs and influenced their optical properties, especially their excitation-dependent emission. These promising results point to potential applications in environmental sensing and energy-related fields.
