1. A regenerable CO2 sheet sorbent, which comprises:
- a. a metal oxide/alkali metal carbonate sorbent, fabricated by the method ofi. preparing a paste-like mixture of particles of metal carbonate and alkali metal carbonate;
ii. forming said paste-like mixture into a sheet;
iii. constraining said sheet within a constraining means, wherein said constraining means inhibits leakage of the particles; and
iv. heating said constrained sheet to convert said metal carbonate to metal oxide.
