“…However, the produced Au nanoparticles had a wide size distribution. Meanwhile, the relative high deposition temperature brings the agglomeration of gold nanoparticles on powder support and the introduction of other elements except carbon and hydrogen in the precursor would induce residual impurities after the gold deposition [11a] . It is still highly desired to take the merit of ALD to manufacture nano‐sized Au catalysts in the range of few nanometers with a narrow size distribution on powdered supports for the growing application of gold catalysis.…”

Nano-sized gold particles have shown unique merits in the field of catalysis, sensing and imaging, whereas their controllable synthesis with sub-nanometer size and narrow distribution on a support still remains a challenge. Herein, we developed a facile and controllable process of atomic layer deposition (ALD) using dimethyl(acetylacetonate)gold (Me 2 Au(acac)) and ozone as the precursor reactants to directly synthesize ultrafine Au nanoparticles on titania support. The size of Au nanoparticles could be precisely controlled via the modulation of depositing temperature and the counter reactant. Additionally, the dispersion of Au nanoparticles on the support is decreased by pre-calcining TiO 2 in air, which is due to the decreased surface hydroxyls concentration on support, leading to less adsorption sites of gold precursor. Moreover, we demonstrated that Au nanoparticles prepared by this method on TiO 2 could function as an effective co-catalyst for photocatalytic hydrogen evolution reaction.

Inducing plasmonic characteristics, primarily localized surface plasmon resonance (LSPR), in conventional AuNPs through particle size and shape control could lead to a significant enhancement in electrical, electrochemical, and optical properties. Synthetic protocols and versatile fabrication methods play pivotal roles to produced plasmonic gold nanoparticles (AuNPs), which can be employed in multipurpose energy, environmental and biomedical applications. The main focus of this review is to provide a comprehensive and tutorial overview of various synthetic methods to design highly plasmonic AuNPs, along with a brief essay to understand the experimental procedure for each technique. The latter part of the review is dedicated to the most advanced and recent solar-induced energy, environmental and biomedical applications. The synthesis methods are compared to identify the best possible synthetic route, which can be adopted while employing plasmonic AuNPs for a specific application. The tutorial nature of the review would be helpful not only for expert researchers but also for novices in the field of nanomaterial synthesis and utilization of plasmonic nanomaterials in various industries and technologies.
