Special Issue Information

Dear Colleagues,

The development of advanced functional materials is one of the current challenges to the efficient production and storage of renewable energy. Solar energy could be used to produce electrical energy or fuels, such as hydrogen and hydrocarbon from water and carbon dioxide, respectively. Hydrogen is also the key to energy transition and achieving decarbonization goals.

This Special Issue is open to original research articles, as well as review papers, helping researchers worldwide understand the latest trends and progress in nanomaterials for different applications, such as solar cell, hydrogen production, fuel cells, batteries, supercapacitors, photo-electrochemical water splitting, etc.

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. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Electrochemical devices on solid electrolytes are closely considered from the point of view of efficient utilization of environmental resources in order to obtain a variety of products, including those with high added cost. This study provides insight into the functionality of electrochemical cells that have been designed with a specific configuration. These cells have the same ionic composition of the anode, cathode, and electrolyte. This was achieved by iron doping of highly conductive (La,Sr)(Ga,Mg)O3−δ electrolyte, and gallium and magnesium doping of the electrode material based on (La,Sr)FeO3−δ. The main focus in this study is on the electrochemical behavior of such cells depending on the oxygen partial pressure in the gas phase, as well as the stability of the electrochemical performance over time for more than 950 h of testing. According to the obtained results, the electrochemical cell with a completely identical ionic composition of electrodes La0.6Sr0.4Fe0.85Ga0.1Mg0.05O3−δ and electrolyte (La0.8Sr0.2)0.98Ga0.7Fe0.1Mg0.2O3−δ demonstrated the best set of optimal performances. This consists of excellent chemical compatibility, high electrochemical activity (0.08 Ω cm2 in air at 800 °C), and a minor degradation rate. Full article
