Web1 de fev. de 2024 · In dark, ca. 24.0% of Cr (VI) was adsorbed by Bi-BDC MOF within 30.0 min. Upon the UV light luminescence, the Bi-BDC MOF could be excited to generate h + and e¯ following Eq. (1). TA was applied to trap the formed h + to accelerate the separation of h + and e¯, in which 100% Cr (VI) could be reduced within 20.0 min. WebFlight history for aircraft - HB-DCR. More than 7 days of HB-DCR history is available with an upgrade to a Silver (90 days), Gold (1 year), or Business (3 years) subscription.
