A 2D/1D heterojunction nanocomposite built from polymeric carbon nitride and MIL-88A(Fe) derived α-Fe₂O₃for enhanced photocatalytic degradation of rhodamine B

Abstract

2D/1D heterojunction α-Fe2O3/C3N4 photocatalysts containing α-Fe2O3 microrods and polymeric carbon nitride flakes are synthesised through the calcination of Fe-based metal-organic frameworks and boost the visible light photocatalytic degradation of rhodamine B.

Introducing anthracene and amino groups into Ln-OFs for the photoreduction of Cr(vi) without additional photosensitizers or cocatalysts

“…[17][18][19] Some typical inorganic photocatalysts with multifunctional characteristics have been reported by scientific researchers, such as TiO 2 , α-Fe 2 O 3 , In 2 S 3 , and ZnO. [20][21][22][23][24] However, there are some shortcomings, such as the electronhole pair recombination rate, fast agglomeration speed, and low solar energy utilization, which limit the efficiency of the above catalysts for Cr(VI) removal. [25][26][27] Therefore, the development of efficient photocatalysts to adsorb and convert Cr(VI) into a less toxic product Cr(III) is highly desired.…”
