Special Issue Information

Dear Colleagues,

Gold is a perfect example of a material that is inert in its bulk form and highly active in the nanoscale form. Due to their unique properties, gold nanoparticles attract the attention of a large number of scientists around the world. Materials based on gold nanoparticles are used in electrochemistry, medicine, biophotonics, and sensor technology. However, gold nanoparticles are most widely used in catalysis. The classic works of M. Haruta served as the starting point for thousands of studies on catalysis on gold nanoparticles. For more than 30 years, despite thousands of published articles, interest in this area has not decreased.

The question of why gold shows such extraordinary properties in its nanoscale form is still debatable, and certainly requires additional research. However, materials based on gold nanoparticles are increasingly being used, and no less interesting are the investigations of aspects such as: mechanisms of elementary processes occurring on the surface of gold nanoparticles; controlled modification of gold nanoparticles; investigation of properties of new materials based on gold nanoparticles; bimetallic gold-containing nanostructured systems; functionalization of gold nanoparticles for use in specific conditions; design and synthesis of composite materials based on gold nanoparticles with specified properties; and the search for new applications of materials based on gold nanoparticles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The hydrogenation features of gold nanoparticles deposited on highly oriented pyrolytic graphite were determined, and composite nanostructures consisting of pure and hydrogenized gold were synthesized. Methods of scanning tunneling microscopy and spectroscopy have been successfully used to probe the bottom of the conductive band and to determine the shape of the electron energy barrier in hydrogenized gold. Considering models of surface and volume hydrogenation, we have shown that no hydrogen dissolution occurred in gold nanoparticles, but all changes in their electronic structure were associated with surface processes. The results of the quantum chemical simulation also corresponded with this conclusion. Full article
