Facile synthesis of pentacle gold–copper alloy nanocrystals and their plasmonic and catalytic properties

Abstract: Control over the size and shape of nanostructures is important for many applications but challenging, especially for bimetallic systems. Here, the authors report the size-controlled synthesis of star-shaped gold–copper nanocrystals and show their applications in catalysis and photothermal therapy.

From plasmon-enhanced molecular spectroscopy to plasmon-mediated chemical reactions

Abstract: The excitation of surface plasmons (SPs) — collective oscillation of conduction-band electrons in nanostructures — can afford photon, electron and heat energy redistribution over time and space Making use of this ability, plasmon-enhanced molecular spectroscopy (PEMS) techniques with ultra-high sensitivity and surface selectivity have attracted much attention and have undergone considerable development over the past four decades Recently, the development of plasmon-mediated chemical reactions (PMCRs) has shown the potential to have a large impact on the practice of chemistry PMCRs exhibit some obvious differences from and potential advantages over traditional thermochemistry, photochemistry and photocatalysis However, our physicochemical understanding of PMCRs is still far from complete In this Review, we analyse the similarities and distinctive features of PEMS and PMCRs and compare PMCRs with traditional photochemical and thermochemical reactions We then discuss how PMCRs can be improved by rationally designing and fabricating plasmonic nanostructures, selecting suitable surface and interface mediators and teaming them synergistically Surface plasmons can redistribute photoenergy over different time, space and energy scales and have been exploited in new spectroscopic techniques This Review reports on how surface plasmons can also drive chemical reactions by localizing photon, electronic and/or thermal energies

Luminescent graphene quantum dots as new fluorescent materials for environmental and biological applications

Abstract: Luminescent graphene quantum dots (GQDs) have attracted tremendous attention from the scientists in chemistry, materials science, physics and biology, because of their superiority of good stability, excellent optical and electrochemical properties, resistance to photobleaching and low cytotoxicity. We summarize the recent advances in the preparation and the properties of GQDs and their applications in environmental and biological areas. In addition, we discuss the future development of GQDs.
