Special Issue Information

Dear Colleagues,

Nanostructured materials are, nowadays, widely employed for a large variety of energy-related applications and devices, including catalysis, water-splitting, solar cells, fuel cells, supercapacitors, batteries. For all of these purposes, nanomaterials are in strict contact with liquid, solid or quasi-solid electrolytes, thus making possible characterize them through electrochemical techniques. Among the different methods, electrochemical impedance spectroscopy (EIS) demonstrated to be effective in characterizing nanostructure materials, being easy, fast, low-cost, non-destructive, and often being employable in situ, i.e., directly in real operating devices. Through EIS, several physical and chemical properties of nanostructured materials can be investigated, as well as different ionic and electronic processes involved in their use. This Special Issue is intended to be a collection of reviews and original papers focused on the most recent development in characterization of nanomaterials for energy application trough the EIS technique.

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. Nanomaterials 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 1200 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 optical and electrical characteristics of a graphene oxide solution (GS) with different graphene oxide (GO) concentrations in de-ionized water are investigated via the electrochemical impedance spectroscopy (EIS) method. The measurement results produced by the EIS for the GS are represented with both Bode and Nyquist plots in a frequency range from 1 kHz to 10 MHz. Using these results, we develop an equivalent circuit model as a function of the GO concentration, representing the GS as a mixed circuit of two-dimensional (2D) GO dispersed in parallel in de-ionized (DI) water. The underlying physics of the current-flowing behavior in the GS are explained and interpreted using empirical circuit models; the circuit model also shows that highly resistive GO becomes conductive in GS form in the DI water. The findings in this work should draw new attention toward GSes and related applications, including functional composite materials, catalysts, and filter membranes. Full article
