Abstract
A resistively heated element can include a base, an insulating material, optional spacers, active coatings, and optional electrodes. A resistively heated element can be formed by preparing an insulating coating solution, depositing the insulating coating on a base, and curing the insulating coating. Additionally or alternatively, an insulating material can be connected to the base. A method of operation can include heating the thermal reactor and introducing the reactants to the thermal reactor.
