In-situ synthesis of cuprous oxide nanofluid using ribose for enhanced thermal conductivity and stability

Abstract

Enhancing the thermal properties of conventional heat transfer fluids represents a significant technological challenge. In this context, nanofluids have emerged as a promising solution, emphasizing the need for simpler and more convenient synthesis methods. This study introduces a novel, eco-friendly, one-step synthesis method, overcoming the complexities of traditional two-step processes. The resulting nanofluid generated by using ribose as a reducing agent, consists of cuprous oxide particles at the nano scale, and the fluid itself exhibits Newtonian behavior. With an impressive thermal conductivity of 3.052 W m−1 K−1, the nanofluid exhibits stability for a noteworthy 4-month duration, achieved through the strategic addition of sodium lauryl sulfate. This breakthrough positions the nanofluid as a compelling option for diverse applications in thermal energy storage and management. © 2024 Elsevier Inc.
