Special Issue Information

Dear Colleagues,

Nanoporous metals prepared by the dealloying (selective leaching) of a solid-solution alloy or compound represent an emerging class of materials. Nanoporous metal has a three-dimensional structure of randomly interpenetrating ligaments/nanopores, of which sizes can be tuned, from 5 nm to several tens of microns, by altering conditions (dealloying time, temperature and subsequent thermal coarsening). Nanoporous metals have several merits for application compared with other nanostructured materials; bicontinuous structure, tunable pore size, bulk form, good conductivity, and high structural stability. Therefore, nanoporous metal is an ideal 3D material to meet various applications, and the attractive versatile functionality such as catalysis, optical sensing, actuation or energy storage and conversion has been emerged. The understanding of the atomistic description of surface roughening and nanopore formation is also important to maximize the functionality.

This Special Issue focuses on recent advances of nanoporous metals by alloy corrosion from fundamental aspects to various applications. We welcome contributions from experimentalists, theorists, and computational scientists in this research field.

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 papers will be 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. Metals 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 1000 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.

We performed in-situ transmission electron microscopy (TEM) on a dealloyed nanoporous NiCo catalyst used for the dry reforming of methane (DRM) to investigate the origin of the catalytic activity and structural durability. The in-situ observations and local chemical analysis indicated that the DRM induced chemical demixing of Ni and Co accompanied by grain refinement, implying possible “synergic effects” in a general bimetallic NiCo catalyst when used for the DRM.
