In view of energy and environmental issues, research on gold nanoparticle (Au NP)-based catalysts is currently experiencing rapid progress due to the promising applications to energy-saving "green" organic synthesis, environmental purification, and artificial photosynthesis. Firstly, Au NP loaded on metal oxides activates oxygen on the surface at low temperature to induce a high level of thermocatalytic activity for many important reactions. The dominant factors for activity are the size and shape of Au NP, and the electronic state effectively tunable by the support in contrast to the bulk-junction system. Secondly, Au NP, uniquely, has localized surface plasmon resonance (LSPR) matching well to the solar spectrum. Au NP-semiconductor heteronanostructures (HNSs) have emerged as a new class of visible-light photocatalysts. In terms of the so-called plasmonic photocatalyst, Au NP acts as a photosensitizer and/or electric-field amplifier for incident light. The activity depends on the efficiencies of light harvesting, charge transfer and separation at the interfaces, and surface redox reactions. The optical property of Au NP is sensitive to the size and shape, and the direction of the interfacial electron transfer can be manipulated through the Au particle-size control. Thus, improvement in activity is a great scientific challenge, requiring rational design and exquisite synthetic techniques. Thirdly, the development of technologies for chemical-to-electricity and solar-to-chemical conversions is crucial for realizing a sustainable society. Au NP-semiconductor HNSs are also attractive as electrocatalytic electrodes for fuel cells and photoelectrochemical cells for artificial photosynthetic reactions.
The aim of this Special Issue is to attract leading researchers in the area of Au NP-based catalysts in an effort to highlight the latest exciting developments to promote concrete applications. Accepted contributions will include the design, synthesis and fundamental properties of Au NP-based catalysts, and their applications to chemical transformations and electrochemical devices.
