Abstract

Graphical abstract: Highlights: Thermopower waves (TWs) are based on a heat transfer process. Production of nanoyarn using MWCNT and PVA. Formic acid and methanol were used as liquid fuels for TWs. Potassium nitrate and sucrose were used as solid fuels for TWs. Abstract: Thermopower waves (TWs) are based on a heat transfer process that occurs by combusting chemical fuels with the help of nanomaterials. As a result of this process, electrical energy is generated. Within the scope of this article, studies were carried out to increase the energy production performance of the prepared nano yarns, and catalysts were used to increase the catalytic reaction. For this, in the first step, nano yarn was prepared using multi-walled carbon nanotubes (MWCNT) and polyvinyl alcohol (PVA). The nano yarn fibers were characterized by a scanning electron microscope (SEM). In this test system, formic acid and methanol were used as liquid fuels and potassium nitrate and sucrose were used as solid fuels. In most of the experimental outputs, a minimum of 2 mV, and a maximum of 8 mV electrical energy were obtained. According to the experimental data of the study, it was observed that the used catalyst activates the thermopower-based energy system. This study is a study that will guide future studies on electrical energy-based energy production from derivatives of carbon-based nanomaterial.
