Photo/electrocatalysis and photosensitization using metal nanoclusters for green energy and medical applications

Abstract

This review summarizes recent developments in the photo/electro catalytic and photosensitizing characteristics of metal and alloy NCs for green energy and medical applications.

Controlled colloidal metal nanoparticles and nanoclusters: recent applications as cocatalysts for improving photocatalytic water-splitting activity

“…2). 34,79,[115][116][117][118][119][120][121][122] In this way, the syntheses and applications are being actively investigated for metal NPs and metal NCs at present. Multiple reviews have been published on the recent research development of such metal NPs and NCs.…”

Understanding and controlling the efficiency of Au24M(SR)18nanoclusters as singlet-oxygen photosensitizers

“…These results, methodologies, insights, and conclusions are expected to provide further ideas and incentive for using atomically precise gold nanoclusters as efficient photosensitizers, which is a topic of current interest for both fundamental and applied research. 95,96 Experimental TREPR For the TREPR measurements, a pulsed laser beam from a Nd:YAG laser (Quantel Brilliant, pulse length 5 ns, pulse energy 5 mJ, and pulse repetition rate 20 Hz) was used for the optical excitation of the samples at 532 nm. At this wavelength, the absorption of all Au 24 M(SR) 18 clusters is signicantly larger than for nitroxides.…”

Atomic-level separation of thiolate-protected metal clusters

“…Therefore, research on alloy clusters has recently become a hot topic. 23,53,[162][163][164][165]172, To deeply understand the correlation between the structure and physical/chemical properties in such an alloy cluster, it is necessary to control the chemical composition of the alloy cluster. Synthesis methods with atomic precision have already been established for several alloy clusters.…”

“…45 In parallel with these studies, studies on the application of these precisely controlled Au n (SR) m and related clusters for chemical sensors, 46,47 photosensitization, 48 catalysts, 49,50 and solar cells 51,52 were conducted. 53 Thus, high-resolution separation techniques have played an extremely important role in the study of Au n (SR) m clusters. Recently, some stable metal clusters can be synthesized with atomic precision.…”
