Investigation on the thermal conductivity and convective heat transfer enhancement in helical coiled heat exchanger using ultrasonically prepared rGO–TiO₂ nanocomposite-based nanofluids

Indian Chemical Engineer (2019)

Neeraj R. Koshta Bharat A. Bhanvase Shivani S. Chawhan Divya P. Barai Shirish H. Sonawane

This work deals with sonochemical synthesis of finely dispersed reduced graphene oxide–TiO2 (rGO/TiO2) nanocomposites with successful immobilisation of TiO2 nanoparticles on rGO. Structural and morphological analysis of prepared rGO/TiO2 nanocomposite was done with the use of UV/VIS, TEM, XRD and FTIR analysis that confirms the formation of finely dispersed rGO/TiO2 nanocomposite. A helical coiled heat exchanger was used for examining convective heat transfer enhancement exhibited by the prepared rGO/TiO2 nanocomposite-based nanofluid. Thermal conductivity enhancement of rGO/TiO2 nanocomposite-based nanofluids with the nanocomposite loading of 0.1–0.5 volume % in water was investigated. An investigation on improvement in the heat transfer coefficient was carried out at different loading of rGO/TiO2 nanocomposite in base fluid at various Reynolds number values. Percentage enhancement in the heat transfer coefficient was around 35.7% for 0.25 volume % concentration of rGO/TiO2 nanocomposite in base fluid.

A review of graphene‐TiO₂ and graphene‐ZnO nanocomposite photocatalysts for wastewater treatment

Water Environment Research (2021)

Kunal G. Thakre Divya P. Barai Bharat A. Bhanvase

Technologies for wastewater remediation have been growing ever since the environmental and health concern is realized. Development of nanomaterials has enabled mankind to have different methods to treat the various kinds of inorganic and organic pollutants present in wastewater from many resources. Among the many materials, semiconductor materials have found many environmental applications due to their outstanding photocatalytic activities. TiO2 and ZnO are more effectively used as photocatalyst or adsorbents in the withdrawal of inorganic as well as organic wastes from the wastewater. On the other hand, graphene is tremendously being investigated for applications in environmental remediation in view of the superior physical, optical, thermal, and electronic properties of graphene nanocomposites. In this work, graphene-TiO2 and graphene-ZnO nanocomposites have been reviewed for photocatalytic wastewater treatment. The various preparation techniques of these nanocomposites have been discussed. Also, different design strategies for graphene-based photocatalyst have been revealed. These nanocomposites exhibit promising applications in most of the water purification processes which are reviewed in this work. Along with this, the development of these nanocomposites using biomass-derived graphene has also been introduced. PRACTITIONER POINTS: Graphene-TiO2 and graphene-ZnO nanocomposites are effective for wastewater treatment through photocatalysis. These nanocomposite photocatalysts have been used in the form of membrane as well as antibacterial agents. Synthetic strategies and design considerations of graphene-based photocatalyst play a major role. Biomass-derived graphene-TiO2 and graphene-ZnO nanocomposites have also found application in wastewater treatment.
