Enhanced photocatalytic CO₂ reduction over Co-doped NH₂-MIL-125(Ti) under visible light

Abstract

Photocatalytic CO2 reduction coupled with the selective oxidation of benzylic alcohols can be achieved over Co/NH2-MIL-125(Ti) upon visible-light irradiation.

Experimental and Theoretical Study on the Interchange between Zr and Ti within the MIL‐125‐NH2 Metal Cluster

“…The photoactivity of metal exchanged MIL‐125‐NH 2 has been measured by others [1,3,9] as show in Table 3. In the photocatalytic reduction of CO 2, the acetonitrile was chosen to increase the solubility of CO 2 in the mixture.…”

Temperature modulation of defects in NH2-UiO-66(Zr) for photocatalytic CO2 reduction

“…For example, Zr-MOF-473 K displays the highest activity with about 129.8 μmol g cat −1 h −1 of the HCOOH produced in 10 h irradiation, much higher than that of Co-doped NH 2 -MIL-125(Ti) (38.4 μmol g cat −1 h −1 ). 40 Moreover, the photocatalytic performance of the defect-free MOF was also investigated and its activity is significantly lower, compared to those of Zr-MOF- T samples. This indicates that the defects in NH 2 -UiO-66(Zr) play an important role in photocatalytic CO 2 reduction.…”

Visible-Light-Driven Photocatalytic Coupling of Benzylamine over Titanium-Based MIL-125-NH2 Metal–Organic Framework: A Mechanistic Study

“…MIL-125 family 28 is the most studied among them. 22,[25][26][29][30][31][32][33] An important feature that makes interesting MIL-125(Ti) family for applications is their good stability upon water adsorption/desorption. 30 Their structure is constituted by Ti8O8(OH)4 rings (see Figure 1a) interconnected by bitopic organic linkers, to form a centered cubic structure.…”
