In situ construction of a C₃N₅ nanosheet/Bi₂WO₆ nanodot S-scheme heterojunction with enhanced structural defects for the efficient photocatalytic removal of tetracycline and Cr(vi)

Abstract

Building step-scheme (S-scheme) heterojunctions is newly emerging to be an efficient means to get excellent photocatalysts for water pollution control. Herein, a 2D/0D S-scheme heterojunction of C3N5/Bi2WO6 is synthesized by...

“…OH, h + and O 2 •– ) in the reaction further confirms that photogenerated holes and electrons are responsible for the photocatalytic reaction. 48 , 49 …”

Rational Construction of Z‐Scheme Charge Transfer Based on 2D Graphdiyne (g‐CnH2n−2) Coupling with Amorphous Co3O4 Quantum Dots for Efficient Photocatalytic Hydrogen Generation

“…The construction of heterojunction is considered one of the most efficient tactics to optimize the photocatalytic H 2 production performance of photocatalysts. [ 38–42 ] However, many shortcomings exist in the traditional heterojunctions. For example, Type‐II and p–n heterojunctions enhanced the photogenerated charges transfer efficiency, and the redox capability of photocatalysts was reduced.…”

Photochemical synthesis of bimetallic CuNiSxquantum dots onto g-C3N4as a cocatalyst for high hydrogen evolution

“…[3][4][5][6] However, various kinds of shortcomings including environmentally pollution, poor visible-light absorption rate, high recombination rate, and chemical instability limit the application of these photocatalysts. [7][8][9] Thus, graphitic carbon nitride (g-C 3 N 4 ), as a 2D novel metal-free polymeric semiconductor photocatalyst, has shown a great development potential owing to its suitable band gap (2.7 eV), low-cost synthesis, thermal stability, environment friendliness, and fascinating planar structure. [10][11][12][13] However, the hydrogen production rate (HER) of pristine g-C 3 N 4 is severely restricted by its low specific surface area, weak absorption, and fast recombination of photogenerated electron-hole pairs.…”
