Effect of improved sol-gel method on composition and micro morphology of Ca3Co4O9

Ca3Co4O9 is a potential high temperature thermoelectric material. We explore the hydrothermal treatment improved sol-gel method to prepare Ca3Co4O9 thermoelectric materials. We find that this treatment can increase the thermoelectric performance of the samples compared with the conventional citric a...
