From: Catalyst-TiO(OH)2 could drastically reduce the energy consumption of CO2 capture
Proposed catalytic mechanism. Three possible pathways for TiO(OH)2 to accelerate CO2 absorption and desorption with MEA being a sorbent are presented. The hydroxyl group of TiO(OH)2 accelerates both protonation and deprotonation reactions and thus CO2 capture through reversible sorption and desorption via the special Lewis structure or the dual weak alkalinity and acidity of TiO(OH)2
