Use of multifunctional nanoporous TiO(OH)2 for catalytic NaHCO3 decomposition-eventually for Na2CO3/NaHCO3 based CO2 separation technology

► Nanoporous TiO(OH)2 reduces CO2 desorption activation energy by ∼50%. ► The associated CO2 desorption rate constant can increase by as high as 10 times. ► A catalytic mechanism is proposed for the catalytic CO2 separation technology. ► The economic impact of the technology on CO2 separation could be considerable.
