Abstract

Global growth of energy transition has increased in the last decades. One of the prominent alternatives of energy carrier other than fossil fuel and electricity is hydrogen fuel. In addition to electrolysis, photocatalytic water splitting offers clean way of producing green hydrogen. It employs solar irradiation to release electron for splitting water into hydrogen and oxygen. Currently, photocatalysis only effective under high frequency ray, such as ultraviolet. To enhance the range of absorbed light, a new trend to incorporate plasmonic heating process using low band-gap metal, i.e. gold and silver, has been developed. This mechanism, however, is sensitive to its thermal characteristics due to scattering process. This study investigates thermal conductivity of iron-based metal under various heat treatment. The result shows that increasing annealing temperature from 700 ℃ to 800 ℃ reduces the conductivity by 6%. This reduction is a result of the increase of grain boundary length, allowing the phonon to scatter during the transfer between the grains, increasing its thermal resistance. Moreover, both variation shows quadratic increase of conductivity as the temperature rises. On average, the thermal conductivities are observed at 9.01 a W/m·°C and 8.41 W/m·°C for samples under 700 ℃ and 800 ℃ annealing, respectively.
