This new catalyst cleans benzene from air using UV light, processing 1.71 liters of air per minute, removing benzene at 21.9 micromoles per gram per hour, and using light efficiently with a quantum yield of 0.000608 molecules per photon per gram.
Scientific Claim
The ZST photocatalyst achieves a clean air delivery rate of 1.71 L min⁻¹, a removal efficiency rate of 21.9 µmol g⁻¹ h⁻¹ with 10% efficiency, and a mass-normalized apparent quantum yield of 6.08 × 10⁻⁴ molecule photon⁻¹ g⁻¹ for the photocatalytic oxidation of 1 ppm benzene under 1 W UV irradiation.
Original Statement
“achieves a clean air delivery rate of 1.71 L min-1 with a 10% removal efficiency rate of 21.9 µmol g-1 h-1 and a mass-normalized apparent quantum yield of 6.08 × 10-4 molecule photon-1 g-1”
