“…In this study, tetra-methylammonium hydroxide (TMAH) and Gum Arabic (GA) were used to coat Fe3O4 and CNT nanoparticles, respectively. Similarly, Jaiswal et al, [40] also followed the single-step method for synthesizing Cu-Pd hybrid nanofluids. Two-step method was applied for water-EG based TiO2-Cu hybrid nanofluid with the inclusion of SDBS surfactant for achieving the long term durability Khairul et al, [41].…”

The recent studies on nanotechnology have reported rapid development of nanofluids in various aspects due to the enhanced thermophysical and heat transfer properties of nanofluids. This paper reviews the preparation methods and some challenging issues of hybrid nanofluids during the Preparation of hybrid nanofluids. One-step and two-step are mainly the preparation methods of hybrid nanofluids. Compared to the one-step method, the two-step method is a widely used technique for preparing nanofluids due to its simplicity, whereas this technique has a complexity of achieving stability of hybrid nanofluids. On the contrary, the one-step is very flexible for achieving uniformity of nanofluids with comparatively high production cost. Some researchers followed various techniques such as surfactant addition, surface treatment, and pH modification for preparing a durable nanofluid. However, these methods also have their limitation, such as degrading the thermal attributes of hybrid nanofluids. So, future studies need to address these challenges along with the cost analysis during preparing the hybrid nanofluids.

“…In essence, the gold-palladium nanoparticles have been decorated successfully on the nitrogen-doped carbon nanotubes surfaces using the polyethylene imine reduction method. Additionally, the researchers Jaiswal et al [113] synthesized copper-palladium hybrid nanostructures nanofluids at varying molar ratio. The temperature dependent thermal conductivity of the nanofluids was measured through a hot disc thermal constant analyzer.…”

The novel class of fluids known by nanofluids is composed of colloidal suspensions of solid nanoparticles dispersed in a base fluid. When the solid nanoparticles are made of noble metals they can be named as noble metals nanofluids or noble nanofluids for short. This review attempts to offer a comprehensive survey along with a critical analysis of the noble metals nanofluids and their hybrids. Hence, the nanofluids having gold, silver, palladium, platinum, iridium, among others, nanoparticles are overviewed, giving emphasis to their superior thermophysical characteristics, stability, synthesis easiness, and potential applications. This work summarizes the published research findings about the noble metal nanofluids including the synthesis methods, heat transfer underlying mechanisms, and their performance evaluation in heat transfer and thermal energy storage purposes. This work intends also to provide practical insights in applications like Concentrated Solar Power systems, transformers, heat exchangers and heat pipes, cooling of electronics, among others. Also, it is highlighted the impact of the different formulations, temperature and pH values, and surfactants in the thermal conductivity, specific heat, and viscosity of these nanofluids. Besides, the interactions between the metal nanostructures and the base fluid molecules as viscosity and thermal conductivity determiners are discussed. Finally, the limitations, challenges, and prospects of the noble nanofluids are addressed such as their scalability and investment cost in large-scale applications.

“…These preferences have triggered extensive investigations in order to mitigate the problems associated with the application of single-NP-based NFs. A number of methods that include ultrasonic methods [ 11 ], the addition of surfactants [ 12 ], pH modification [ 13 ], surface modification [ 14 , 15 ], etc., have been tried in order to improve the stability of NFs. These methods can be grouped into covalent coupling or chemical modification, physical adsorption/treatment, and electrostatic bonding [ 16 ].…”

In the present work, a new kind of nanocomposite (NC)-based solid component was prepared for formulating nanofluids (NFs). The NC comprised metal oxide (titanium dioxide, TiO2) dispersed in a conducting polymer with polyaniline (PANI) and chemically linked silyl–alkyl units in it (PSA) that were designated as T-PSA NC. The NFs with ethylene glycol (EG) as a base fluid were prepared with T-PSA NCs with various compositions of TiO2 and PSA as well for various concentrations of T-PSA NCs. The scanning electron microscopic evaluation of the NC revealed that PSA deposition on TiO2 nanoparticles (NPs) decreased particle agglomeration. The PSA coating on the TiO2 NPs did not influence the crystalline structure of the TiO2 NPs, according to the X-ray diffraction patterns. The thermophysical characterization and molecular interaction features of the NFs at 303 K including a novel inorganic–organic T-PSA NC, were detailed. Furthermore, the stability of the T-PSA NC-based NFs was investigated experimentally using the zeta potential, and the particle size distribution change was analyzed using the dynamic light scattering (DLS) method. The T-PSA NCs had particle sizes that were significantly bigger than pristine PSA and pure TiO2. Most of the preparation conditions used to produce the T-PSA NCs resulted in moderately stable suspensions in EG. The results revealed that the ultrasonic velocity increased with the increase in the concentration of T-PSA NC mass % in the NFs, the refractive index and thermal conductivity increased with the increase in the concentration, and the surface tension exhibited a linear change when the ratio of mass % concentration of the T-PSA NCs increased. The combined presence of components that synergistically contribute to the electro, thermal, optical, and rheological properties is expected to attract advanced applications for NFs.
