The present teachings are directed toward an electrocatalytic cell including a barrier, having at least a first side and a second side opposite the first side, comprising a material permeable to oxygen ions and impermeable to at least CO 2 , CO, H 2 , H 2 O and hydrocarbons, an electrical power supply in communication with the barrier, a catalyst adjacent the first side of the barrier, a supply of feedstock components in communication with the first side of the barrier, a supply of a carrier gas component in communication with the second side of the barrier; wherein the feedstock components contact the catalyst and react to form hydrocarbon-containing components and oxygen-containing components, and the electrical power supply biases the barrier to thereby conduct oxygen ions from the first side to the second side. Also presented are a device and methods for producing carbon nanotubes. |
