Band gap engineering of CuS nanoparticles for artificial photosynthesis

Biomimetic strategies to produce catalytically reactive CuS nanodisks

“…These values are consistent with bulk CuS of the hexagonal wurtzite structure that has an approximate band gap of 2.5 eV. 10 From the results presented above, only the acidic amino acids (Glu and Asp) are able to make stable CuS materials. Using these amino acids, the fabrication of CuS nanodisks occurs, where the other biomolecules used led either to material precipitation or the lack of particle formation.…”

“…[7][8][9] These p-type semiconductor materials have a narrow band gap, which allows for efficient use of visible light for photocatalytic reactions as compared to TiO 2 , SrTiO 3 , and ZnO that require UV light. 10,11 Beyond the narrow band gap, CuS materials also possess a strong plasmon band that is shied into the near IR region of the electromagnetic spectrum. Such a plasmon position is highly unique, making it of interest for biomedical applications.…”

“…While great advances in synthesizing CuS structures have been achieved to control the plasmon, [12][13][14] band gap, 10,15 and morphology of these materials, 16 these methods generally require unsustainable conditions. [17][18][19][20] In this regard, CuS production typically requires harsh conditions, toxic organic solvents, 21 and/or complex instrumentation that can limit their long-term production.…”

A review on the progress of nanostructure materials for energy harnessing and environmental remediation

“…This can be substantiated by the BiVO 4 synthesis, where, at relatively low temperature, scheelite-monoclinic phase was observed, while, at higher temperature, the phase changed to tetragonal [144]. It is generally used for synthesizing crystal-modified CuS, classical non-metaldoped photocatalysts, and heterojunction composite with higher surface area [145][146][147][148].…”

The effects of thioacetamide/copper molar ratio and reaction time on the phase evolution, morphology, optical, and photocatalytic properties of the nanosheets‐based flower‐like copper sulfide

“…Self‐organization combines the nanostructures into new 3D nanostructured materials . The chalcogenide semiconductors have extensive applications in various fields such as cancer therapy, solar cell, DNA biosensor, Photo‐acoustic agent, antibacterial, optical and photocatalytic, optoelectronics, magnesium secondary batteries, and artificial photosynthesis . The band gap of the semiconductor, which plays a significant role in the photocatalytic properties of copper sulfide nanoparticles, can be controlled according to the stoichiometry of Cu:S and the type of synthesis method.…”
