Are gold nanoclusters good for photothermal conversion?
Learn more. Gold nanoclusters (AuNCs) are highly promising for applications in photothermal conversion due to their exceptional surface area and optical properties. However, their high surface energy often leads to aggregation, compromising stability and performance.
What is a Gold nanocluster?
In recent decades, noble metal nanoclusters especially gold have attracted extensive attention. The size of gold nanoclusters (Au NCs) is typically less than 2 nm, which is between that of small molecules and metal nanoparticles (NPs).
Why is Gold nanocluster research difficult?
Several theoretical obstacles to gold nanocluster (Au NCs) research set it apart from experimental methods. The relatively complex interactions between gold atoms and their ligands make it theoretically difficult to accurately model Au nanoclusters’ electronic structure. [11, 12, 13].
What are ultrasmall gold nanoclusters?
Ultrasmall-sized gold nanoclusters with discrete energy levels exhibit unique optical absorption, radiative transitions, and excited-state dynamics (Aikens, ).
What are atomically precise gold nanoclusters (AU NCS)?
Atomically precise gold nanoclusters (Au NCs) have high specific surface area and abundant unsaturated active sites. Traditionally, Au NCs are employed as thermocatalysts for multielectron transfer redox catalysis.
Why are gold nanoparticles important?
Gold nanoparticles have significant attention due to their unique properties and wide range of characteristics in catalysis, biomedicine, energy conversion, and optoelectronics. These applications are supported by the chemical stability of gold and its amazing electrical and optical characteristics [8, 9, 10].
