Thermoelectric energy conversion technology is attracting great attention for the conversion of waste heat into electricity. Meso/macrostructured strontium oxide, with well defined organisation, may play a pivotal role in advancing properties of thermoelectric materials. Sol-gel processing is a method of choice to prepare such materials. This synthesis pathway offers several possibilities to induce porosity, mainly by using organic-directed assembly of building blocks or by making use of the intrinsic porosity of gel networks. By making material porous the phonon transport across the material is disturbed which will lead to decrease in thermal conductivity and hence good thermoelectric performance could be achieved. We attempt to compare thermoelectric performance of bulk and meso/macroporous strontium titanate.
