Quantum dots for photocatalysis: synthesis and environmental applications

Abstract

Quantum dots (QDs) with unique properties have been widely employed for energy, environmental, and health care applications. Green natural resources because of their renewability, sustainability, abundance, low cost, and environmental-friendliness...

Silver and Gold Nanoparticles for Antimicrobial Purposes against Multi-Drug Resistance Bacteria

“…In general, about 70 fungi and bacteria are described to be related to oral disease. Au NPs with a size of approximately 30 nm synthesized by green assay through Justicia glauca, displays an antagonistic outcome with Clarithromycin and Azithromycin antibiotics in contradiction of oral pathogenic bacteria and fungi, such as Streptococcus mutans, Bacillus Antimicrobial peptides (AMPs) are debated as elegant substitutes to traditional antibiotics in the battle against multi-drug resistance pathogens which can kill pathogenic bacteria, fungi, and protozoa, according to the broad-spectrum of activity [133][134][135]. Gu and colleagues, first reported the binding of AMPs bound to metal nanoparticles, such as Au, and exhibited that vancomycin bound to Au NPs (Au@Van) through thiol bonds can be active against vancomycin-resistant enterococci [136].…”

Synthesis of two-dimensional ultrathin photocatalytic materials towards a more sustainable environment

“…2D chalcogenide materials composed of metal sulfides, metal selenides and metal tellurides are typical inorganic photocatalysts, and a series of reviews have been published on the preparation of each subclass in recent years. [14][15][16][17][18] In addition, the famous molybdenum sulfides and molybdenum selenides are widely used in photocatalysis as cocatalysts, due to their narrow bandgap (1-2 eV). [19][20][21] Hence, in this review, the emerging 2D bismuth oxyhalides are selected as the representative of 2D inorganic photocatalysts with non-toxicity, high stability and tuneable band structure.…”

Investigation of Ag doping and ligand engineering on green synthesized CdS quantum dots for tuning their optical properties

“…QDs are tiny nanostructures in the range of a few nanometers, which shows the variable optical property with size [13][14]. These exhibit a high surface-to-volume ratio making them highly unstable.…”
