a Impact of thermochemical reactor temperature on CNT yield and CNT production rate (5 vol% H2, 95 vol% CO, 2 g catalyst, 500 sccm, 3 h test duration) (b) impact of H2 content on CNT yield (gas balance CO, 2 g catalyst, 500 sccm, 3 h test duration, 500 °C) c thermodynamic modeling of the effect of temperature and CO2 content on equilibrium and conversion of CO to CNTs (% CO2 represents vol% in feed to thermochemical reactor) (d) Impact of CO2 flowrate on CO2 electrolyzer outlet gas composition (e)>200 h high conversion CO2 electrolyzer stack stability testing (300 sccm CO2 inlet, 5 psi backpressure).
