Special Issue Information

Dear Colleagues,

Nanoporous materials are one of the most useful materials, and their applications can be found in a wide variety of fields, including heterogeneous catalysis, photocatalysis, electrochemical catalysis, adsorptive separation, mixed-matrix-membrane, inorganic membrane, fuel cells, lithium-ion batteries, electrochemical sensors, biosensors, and so on. With the further development and widening of applications, single-structured or single-component material systems are facing their technological limits. Thus, new nanostructured, engineered, multifunctional porous materials have attracted a great deal of attention. For example, hierarchical porosity can improve the mass transfer behavior; thus, the design and synthesis of hierarchical zeolites has been a hot research area. In another example, core-shell structures have found a great deal of potential to compensate for the properties of core and shell materials, respectively, so that unique electrical, optical, chemical, and thermodynamic properties can be obtained, which may be difficult to achieve otherwise.   

The Guest Editor looks forward to collecting a set of recent advances in the related topics, to provide a platform for researchers, and bridge the gap between new materials research and their potential applications. The topics may cover design and synthesis of composite porous materials, characterization of their engineered structures, and potential applications, in which the nanoporous materials can be presented as powder, fiber, or thin film. Both experiments and simulations are welcome.

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. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.

Exploration of efficient catalysts is a priority for the electrochemical nitrogen reduction reaction (NRR) in order to receive a high product yield rate and faradaic efficiency of NH3, under ambient conditions. In the present contribution, the binding free energy of N2, NNH, and NH2 were used as descriptors to screen the potential NRR electrocatalyst among different single or binuclear transition metal atoms on N-doped nanoporous graphene. Results showed that the binuclear Mo catalyst might exhibit the highest catalytic activity. Further free energy profiles confirmed that binuclear Mo catalysts possess the lowest potential determining step (hydrogenation of NH2* to NH3). The improved activities could be ascribed to a down-shift of the density of states for Mo atoms. This investigation could contribute to the design of a highly active NRR electrocatalyst. Full article
