Synthesis and Performance of Large-Scale Cost-Effective Environment-Friendly Nanostructured Thermoelectric Materials

Abstract

Thermoelectricity is a promising technology that directly converts heat energy into electricity and finds its use in enormous applications. This technology can be used for waste heat recovery from automobile exhausts and industrial sectors and convert the heat from solar energy, especially in hot and humid areas such as Qatar. The large-scale, cost-effective commercialization of thermoelectric generators requires the processing and fabrication of nanostructured materials with quick, easy, and inexpensive techniques. Moreover, the methods should be replicable and reproducible, along with stability in terms of electrical, thermal, and mechanical properties of the TE material. This report summarizes and compares the up-to-date technologies available for batch production of the earth-abundant and ecofriendly materials along with some notorious works in this domain. We have also evaluated and assessed the pros and cons of each technique and its effect on the properties of the materials. The simplicity, time, and cost of each synthesis technique have also been discussed and compared with the conventional methods.

Attractive study of the antimicrobial, antiviral, and cytotoxic activity of novel synthesized silver chromite nanocomposites

“…The antimicrobial nanoparticle compounds can be used to overcome antibiotic resistance [ 52 ]. Antimicrobial nanoparticles such as silver nanoparticles have been utilized in biocides for over 120 years [ 53 ]. The technique used to prepare nanoparticles should be efficient, low cost, high yield, and produce very fine nanoparticles [ 54 ].…”

Fast and effective catalytic degradation of an organic dye by eco-friendly capped ZnS and Mn-doped ZnS nanocrystals

“…However, these NPs must be dispersible in water to maximize their performance. Accordingly, the colloidal wet chemical synthesis has emerged as the most popular safe way to produce, at large scale and cost-effective, watersoluble semiconductor NPs with narrow size dispersion and promising optical and electronic properties (Jaldurgam et al 2021).…”

A Review on Doped/Composite Bismuth Chalcogenide Compounds for Thermoelectric Device Applications: Various Synthesis Techniques and Challenges

“…The thermoelectric figure of merit was found to be enhanced by the low lattice thermal conductivity and calculated to be 0.67 at 483 K for Bi 2 Se 1.5 Te 1.5 . 162 Further, a self-propagating high-temperature technique was Hence, there is a suppression in lattice thermal conductivity from 1.07 W/mK to 0.61 W/mK at 300 K, and a ZT of 0.67 at 473 K has been achieved for Bi 0.5 Sb 1.5 Te 3 . 163 Textured BiSbTe 1.5 Se 1.5 was prepared by Oleg et al 164 They achieved a maximum ZT of 0.43 at 500 K using self-propagation hightemperature technique.…”
