摘要: Abstract Polyurethane (PU), a honeycomb structure material, was used as substrate onto which TiO 2 and Cu–TiO were deposited in order to integrate the adsorption property photocatalysts. on PU (TiO /PU) Cu-doped (Cu–TiO synthesized applied removal of Candida famata ( C. ), frequently encountered airborne yeast. The capacities by PU, /PU 1.5 × 10 5 , 3.2 × 10 6.9 × 10 (CFU/cm 3 ) under dark condition 3.3 × 10 1.8 × 10 6 visible light irradiation, respectively. seemed exhibit only an ability for removing aerosols both light. capacity increased 2.6-fold compared that condition. This significant increase attributed Cu dopant, enhanced electron–hole separation efficiency resulting high photocatalytic activity
