Carbon quantum dots (CQDs) offer significant promise across industries due to their distinctive optical properties and strong biocompatibility. However, conventional synthesis methods frequently need more precision in controlling nanoparticle size, shape, uniformity, limiting versatility diverse applications. Therefore, this study introduced an innovative approach synthesising CQDs by combining electrochemical techniques with carbon dioxide (CO2) nanobubbles, circumventing the for surfactant-based exfoliation. According findings, synthesised exhibited remarkable properties, including a high yield of 26.17% average particle size 2.24 ± 1.07 nm. Such characteristics render them exceptionally suitable portable sensors heavy metal detection wastewater. Moreover, investigation revealed outstanding selectivity CQDs, particularly towards iron (Fe3+) ions, but demonstrated limited reactivity lead (Pb2+) copper (Cu2+) ions. The novel also generated non-toxic CQD under supply CO2 which offers scalable avenue developing advanced materials various applications, ion method that relied on sodium dodecyl sulphate (SDS) surfactants without nanobubbles yielded significantly lower 11.2%. In short, incorporating enhanced superior control over shape synthesized CQDs. This successfully produced distinct morphologies provided new understanding mechanism, potential applications sensing environmental monitoring water quality management.
