Studies employing multi-step processes or hydrothermal methods assisted by other techniques, such as microwaves, were excluded. Additionally, selected studies had to incorporate a purification step using microporous membranes, ensuring greater control over the quality and final properties of the synthesized nanomaterials. This systematic approach ensured the selection of studies aligned with the research objectives and consistent methodologies for comparative analysis. Figure presents a decision tree outlining the eligibility criteria used in the selection process. A dataset comprising 157 articles from the literature was compiled, containing information on CD synthesis parameters and their final properties, which is disposed of in the supplementary information.
