Enhanced mass transport of nanofluids have been widely investigated, so that the development of nanofluid-based electrolyte becomes an alternative to improve conductivity and diffusivity of electrolyte. However, the reciprocity of nanoparticles and high ionic strength electrolyte causes stability problem of nanoparticle suspensions. A feasible approach is proposed to fabricate alumina nanofluid-based ferro/ferricyanide electrolyte with increscent electrical conductivity and exercisable stability by introducing nanogrinding together with ultrasonication. Experimental study based on rotating disk electrode exhibits the diffusivity of nanofluid-based electrolyte captures a prominent augment with the increasing of rotating speed, which suggests the superior in limiting currents to pure ferro/ferricyanide electrolyte from a certain rotating speed, which results from the combined effect of convection and percolation behavior under sheared flow. Alumina nanofluid-based electrolyte equipped with improved electrical conductivity is applied in thermogalvanic cells to achieve a favorable figure of merit, contributing to a high energy conversion efficiency for thermogalvanic cells.
