An S-scheme α-Fe₂O₃/Cu₂O photocatalyst for an enhanced primary amine oxidative coupling reaction under visible light

Abstract

Photoredox catalysis under visible light has been recorded as a potential and reassuring recipe for organic synthesis.

Unraveling the photocatalytic electron transfer mechanism in a Ti-MOF/g-C3N4 heterojunction for high-efficient coupling performance of primary amines

“…As shown in Table 2, the TOF of Ti-MOF/g-C 3 N 4 is 5.9 mmol g −1 h −1 was 5.9 times that of NH 2 -MIL-125(Ti) (1.0 mmol g −1 h −1 ). It is notable that this TOF value is higher than that shown by other reported photocatalysts, such as α-Fe 2 O 3 /Cu 2 O, 47 NH 2 -MIL-125(Ti), 48 Ru(bpy) 3 /MIL-125, 49 Pd/BiOCl 50 and Mo 2 C-QDs/C/Bi 2 MoO 6 . 51…”

An S-scheme α-Fe2O3/g-C3N4 heterojunction nanostructure with superior visible-light photocatalytic activity for the aza-Henry reaction

“…On the contrary, the S-scheme heterojunction, preliminarily proved by the aforementioned results of XPS, accurately explains the improved photocatalytic activity of FOCN. 64 Moreover, photodeposition of PbO 2 was conducted to determine the sites for oxidation reaction in the S-scheme heterojunction. As seen in Fig.…”
