It examines their corresponding thermoelectric properties while considering the synthesis methods employed, paying significant attention to those that particularly follow sustainable routes. Additionally, the work addresses current challenges in the field, such as enhancing stability at high temperatures and reducing manufacturing costs. The understanding gained in this field opens avenues for designing more efficient and sustainable devices to convert waste heat into electrical energy, thereby advancing cleaner technologies.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal articlehttps://doi.org/10.1002/sstr.202400136https://onlinelibrary.wiley.com/doi/10.1002/sstr.202400136open access54thermoelectricsthermoelectric materialsenergyWaste heat recoverySeebeck coefficientElectrical conductivityThermal conductivityFigure of meritQuímica inorgánica (Química)MaterialesFísica del estado sólido23 Química2303 Química Inorgánica3322.02 Generación de Energía
