Fabrication of a hybrid phase TiO₂/g-C₃N₄ heterojunction composite with enhanced adsorption and photocatalytic degradation of MB under visible light

Abstract

The heterojunction structure of semiconductor photocatalysts is significant for making full use of their capabilities for organic molecules and dye degradation. In this paper, we present a heterogeneous junction composite...

A Novel Nanogold Composite Fabrication, Its Characterization, and Its Application in the Removal of Methylene Blue Dye from an Aqueous Solution

“…This suggests a significant hydrogen-bonding interaction between C=O and MB [38]. The vibrational modes of the (C=C aromatic) stretching band before adsorption shifted to 1044 cm −1 implying modification of ring vibration, which is indicative of interactions like pi-pi interactions with MB [39]. As the composite structure comprises polymers, the movement of these polymer frameworks could potentially immobilize the nanogold.…”

Fabrication of high photocatalytic activity photocatalysts with TiO2 supported on lamellar BiOCl

“…Consequently, considerable efforts have been directed toward enhancing TiO 2 photocatalysis through the formation of semiconductor heterojunctions with metals or other semiconductors over the past decade. Notable advances include the fabrication of TiO 2 /porous nanosized BiFeO 3 (T/P-BFO) nanocomposites by Humayun, the synthesis of g-C 3 N 4 /TiO 2 heterojunctions by Liu, and the preparation of TiO 2 /RGO/Cu 2 O heterostructures by Chang [9][10][11].…”
