Iron phthalocyanine modified mesoporous titania nanoparticles for photocatalytic activity and CO2 capture applications

Abstract

An iron(II)phthalocyanine (Fepc) modified mesoporous titania (Fepc–TiO₂) nanocatalyst with a specific surface area of 215 m² g⁻¹ has been synthesized by a hydrothermal method. Fepc–TiO₂ degrades one of the highly toxic chemical warfare agents, sulfur mustard (SM), photocatalytically under sunlight with an exposure time of as low as 70 min. Furthermore, the mesoporous Fepc–TiO₂ also captured 2.1 mmol g⁻¹ of CO₂ at 273 K and 1 atm.
