ZnS quantum dot intercalated layered double hydroxide semiconductors for solar water splitting and organic pollutant degradation

Abstract

MIIZnAl-LDH/ZnS QD (MII = Co or Mn) nanocomposites were synthesized by assembling oppositely charged 2D LDH layers and ZnS QDs. The MIIZnAl-LDH/ZnS QDs exhibited enhanced visible light harvesting ability, considerable visible light photocatalytic activity and photostability.

Precious Metal‐Free Photocatalytic Water Oxidation by a Layered Double Hydroxide‐Prussian Blue Analogue Hybrid Assembly

“…Layered double hydroxides (LDHs) consisting of mixedmetal hydroxide layers step forward in photocatalytic water splitting due to their simple synthesis, diversity, abundant active earth-metal centers, and efficient visible light-harvesting properties. [6][7][8][9][10][11][12][13] Although LDHs have been actively used for photocatalytic water splitting due to their high quantum yield and efficiency, only a limited number of studies involve the utilization of ZnCr-LDH as a narrow bandgap semiconductor for the photocatalytic water oxidation process. [14] ZnCr-LDH has been employed either as an individual photocatalyst [15][16][17] or as part of a heterostructure consisting of a combination of suitable semiconductors for overall water splitting.…”

Photocatalytic activity enhancement of carbon‐doped g‐C3N4 by synthesis of nanocomposite with Ag2O and α‐Fe2O3

“…The absorption edge of CGNS is located at 471 nm while it shifted toward higher wavelengths (558 nm) in the GAF. Also, the effective interaction between the α-Fe 6b) [39] :…”

Enhancing the photocatalytic hydrogen generation performance and strain regulation of the vertical GeI2/C2N van der Waals heterostructure: insights from first-principles study

“…6 After the overall water splitting was experimentally achieved with TiO 2 , 7 several photocatalysts, such as metal nitrides, sulphides and oxides, and other bulk materials, have been reported to play a vital role in solar energy conversion and storage process. 8 However, the low solar utilisation of bulk materials hinder their practical application as high-efficient photocatalysts.…”
