AB Concentrating solar power is becoming one of options for producing energy to replace conventionalpolluting energy sources. However, improving the efficiency and reducing the cost of technologies basedon this type of energy to make it more competitive is still a work in progress. This study proposesreplacing the thermal oil used as the heat transfer fluid in the absorber tubes of parabolic trough solarcollectors (PTCs) with nanofluids based on spherical molybdenum disulphide nanoparticles with the aimof improving the thermal efficiency of concentrating solar power plants. The colloidal stability of thenanofluids was verified by UltravioleteVisible spectroscopy, Zeta potential and Dynamic Light Scatteringmonitoring. The presence of spherical MoS2 nanoparticles resulted in an increase of up to 13% in specificisobaric heat and 6% in thermal conductivity compared to thermal oil. Finally, the efficiency of parabolictrough solar collectors was estimated to increase by 5%, which also favours the decrease of pumpingpower and the elimination of selective coatings on the absorber tube. To our knowledge, this is the firsttime that MoS2-based nanofluids are tested as heat transfer fluids in PTCs analysing its implementationin the solar energy application.© 2022 The Authors.
