“…The most commonly utilized method for stability assessment is sedimentation. The basis of this method is the settlement of nanoparticles out of the nanofluid under the influence of gravity [61]. The volume or weight of sediment is a good indication of nanofluid stability.…”

The continuous release of CO2 into the atmosphere as a major cause of increasing global warming has become a growing concern for the environment. Accordingly, CO2 absorption through an approach with maximum absorption efficiency and minimum energy consumption is of paramount importance. Thanks to the emergence of nanotechnology and its unique advantages in various fields, a new approach was introduced using suspended particles in a base liquid (suspension) to increase CO2 absorption. This review article addresses the performance of nanofluids, preparation methods, and their stability, which is one of the essential factors preventing sedimentation of nanofluids. This article aims to comprehensibly study the factors contributing to CO2 absorption through nanofluids, which mainly addresses the role of the base liquids and the reason behind their selection.

“…Polyaniline (PANI) has developed as nano additives for nanofluid system and has attracted great attention among researchers due to its unique behavior such as good in conductivity, cost effectiveness and nontoxic [19][20][21][22][23]. PANI nanofibers are usually synthesized via oxidative polymerization approach and exhibit fiber like morphology that provides higher surface area [24,25].…”

Since a decade ago, investigation on nanofluids has grown significantly owing to its enhanced thermal properties compared to conventional heat transfer fluids. This engineered nanofluid has been widely used in the thermal engineering system to improve their energy consumption by improving the thermal efficiency of the system. The addition of nano-size particles as additives dispersed in the base fluids proved to significantly either improve or diminish the behaviour of the base fluids. The behaviour of the base fluid highly depends on the properties of the additives material, such as morphology, size, and volume fraction. Among the variety of nanoparticles studied, the conducting polymers have been subject of high interest due to its high environmental stability, good electrical conductivity, antimicrobial, anti-corrosion property and significantly cheap compared to other nanoparticles. As such, the main objective of the present review is to provide an overview of the work performed on thermal properties performance of conducting polymers based nanofluids.

“…CuO incorporated into PANI to enhance its magnetic traits, catalytic and directed adsorption sites because of empty d-orbital in CuO [22]. The recent study shows that hybridization of PANI and CuO nanoparticles is thought to provide more effective nano uid behavior than a mono nano uid system [23].…”

Textile dyeing releases over 80% of industrial effluents without proper treatment. Dye discharged into effluents typically need degradation before release into aquatic environments. In this regard, the present paper reports the nanocomposite copper oxide/polyaniline (CuO/PANI) is successfully synthesized by in situ chemical oxidative polymerization method and investigate their catalytic activity against organic dyes and nitro-compounds. CuO nanoparticles are synthesized by colloidal sol-gel method using oxalic acid as capping agent to obtained desired morphology. The elemental composition, unit cell and lattice parameters of nanocomposites are characterized by using XRD. The XRD revealed that nanoparticles are extremely crystalline, but nanocomposites are amorphous because of the presence of polymer. The structural and elemental analysis of CuO and CuO/PANI is confirmed by SEM and EDX analysis. FTIR spectra of CuO showed bending vibration while CuO/PANI showed the presence of benzenoid and quinoid rings. Catalytic productivity of the CuO and CuO/PANI as catalysts in degradation of dyes and reduction of nitro-compounds are also studied. The degradation and reduction processes are monitored through the utilization of UV-Vis spectrophotometer. The catalytic activity of both catalysts is evaluated by several parameters including kapp, degradation/reduction time, % degradation/reduction, degraded/reduced concentration and half-life. Among all substrates, highest kapp is 0.0653 min-1 for CV by CuO while 0.0502 min-1 for EBT by CuO/PANI due to large surface area. On degradation or reduction rate of substrates, the impact of functional group type and orientation, bond type and steric hindrance are also investigated.
