Materials, methods, and systems for reactive capture and conversion of CO2

A method for reducing CO2, utilizing a solid composition, the method comprising:

• a first contacting of the solid composition with CO2 at a first temperature and a first pressure, resulting in chemisorption of the CO2 onto the composition;
• and
• a second contacting of the solid composition with H2 at a second temperature and a second pressure, resulting in a portion of the chemisorbed CO2 reacting to form at least one of CO, methane, or methanol, wherein:
• the solid composition comprises:
• an oxide comprising zinc, aluminum, and copper;
• and
• sodium at a concentration between 5 wt % and 10 wt % present as Na2O dispersed on the oxide;
• the first temperature is between 0° C. and 450° C.,
• the first pressure is between 0.8 bar and 30 bar (absolute),
• the second temperature is between 50° C. and 450° C., and
• the second pressure is between 0.8 bar and 30 bar (absolute).
