Regioselective chemisorption-induced separate deposition of two types of metal nanoparticles on TiO.

The discovery of the excellent thermal catalytic activity of Au nanoparticles (NPs) for CO oxidation (Haruta et al., 1987 [1]) triggered intensive research on thermal and visible photo-catalysis based on these NPs (Ref. [2]).

Dependence of crystal size on the catalytic performance of a porous coordination polymer.

Submicrosized MOF-76(Yb) exhibits a higher catalytic performance for esterification than microsized MOF-76(Yb). Control of the crystal size of porous heterogeneous catalysts, such as PCP/MOFs, offers a promising approach to fabricating high-performance catalysts based on accessibility to the internal catalytic sites.

Rational design and applications of highly efficient reaction systems photocatalyzed by noble metal nanoparticle-loaded titanium(IV) dioxide.

The fundamentals and applications of TiO(2) photocatalysis have been extensively studied in recent decades, the central theme being increasing reaction efficiency. A guideline for achieving so-called "reasonable delivery photocatalytic reaction systems (RDPRSs)" has been presented. This tutorial review summarizes recent developments in the RDPRS-based design of highly efficient photocatalytic reactions by noble metal nanoparticle-loaded TiO(2) (M/TiO(2)).

Au nanoparticle electrocatalysis in a photoelectrochemical solar cell using CdS quantum dot-sensitized TiO2 photoelectrodes.

A significant Au particle size-dependent electrocatalytic effect has been shown in a sandwich type photoelectrochemical solar cell consisting of CdS quantum dot (QD)-sensitized TiO(2) photoelectrodes, Au nanoparticle (NP)-loaded SnO(2) counter electrodes, and a polysulfide electrolyte solution intervening between the electrodes.

Size-dependence of Fermi energy of gold nanoparticles loaded on titanium(iv) dioxide at photostationary state.

TiO(2) particle-supported Au nanoparticles (NPs) with varying sizes and good contact (Au/TiO(2)) were prepared under a constant loading amount by the deposition-precipitation method. The Fermi energy of Au NPs loaded on TiO(2) at the photostationary state (E(F)') was determined in water by the use of S/S(2-) having specific interaction with Au as a redox probe. The E(F)' value goes up as the mean size of Au NPs (d) increases at 3.

All-solid-state Z-scheme in CdS-Au-TiO2 three-component nanojunction system.

Natural photosynthesis, which achieves efficient solar energy conversion through the combined actions of many types of molecules ingeniously arranged in a nanospace, highlights the importance of a technique for site-selective coupling of different materials to realize artificial high-efficiency devices. In view of increasingly serious energy and environmental problems, semiconductor-based artificial photosynthetic systems consisting of isolated photochemical system 1 (PS1), PS2 and the electron-transfer system have recently been developed. However, the direct coupling of the components is crucial for retarding back reactions to increase the reaction efficiency.

Ultrafast photosynthetic reduction of elemental sulfur by Au nanoparticle-loaded TiO2.

Nanometer-sized gold particles with varying mean size from 3.2 to 12.2 nm were loaded on the surfaces of TiO2 particles in a highly dispersed state with the loading amount maintained constant (0.

Photoinduced dissolution and redeposition of Au nanoparticles supported on TiO2.

Au particles (mean size ca. 3 nm) supported on TiO(2) particles were irradiated by UV light (>300 nm) in aqueous solutions at 278 K. Photo-induced dissolution of Au nanoparticles followed by redeposition occurred in aqueous solutions containing halogen ions.
