Special Issue Information

Dear Colleagues,

Given the rapidly changing global climate, advanced inorganic nanomaterials are in demand and essential in applications involving state-of-the-art clean energy and environmental remediation technology. The nanotechnology of these (0–3D) inorganic nanomaterials involves manipulating materials at the nanoscale, reducing their size in nano dimensions and atomic/molecular clusters. As a result, their optical, magnetic, electrical, and electrochemical properties vary from those of the bulk materials irrespective of their position in the periodic table. The combination of those advanced nanomaterials, e.g., MXene, MOF/COF, and novel carbon nanostructures such as carbon nano-onions (CNO) and graphene nanoplatelets (GNP), could be a game changer for novel electrochemical applications. The clean and environmentally friendly electrochemical process and its technologies are preferred. The 2D advanced nanofunctional materials are observed to have unique structural and electrochemical properties at interfaces. At the same time, their corresponding oxides/sulfides/phosphides show exciting and complex electrochemical responses due to their variable redox states.

The presence of photons or their irradiation in the existing electrochemical system makes it more complex and nonlinear. However, in situ electrochemical tools paired with computational techniques are available for use in understanding the complexity. Even fractional atomic alteration through doping can lead to significantly modified opto-electrochemical properties. Doping with unique nanocarbons, such as CNO and GNP, of a few atomic percent could result in excellent metal-free carbocatalysts for environmental remediation.

This Special Issue of the MDPI journal Materials represents an excellent opportunity to explore the unexplored complex photoelectrochemical properties/applications of advanced inorganic nanomaterials. We as Editors are inviting materials scientists, physicists, chemists, chemical engineers, and electrochemists to come forward and contribute to resolving the challenges and revealing the undiscovered potentiality of all 2D nanomaterials, oxides/sulfide/phosphides, MOFs/COFs, LDHs, MXenes, CNOs, GNPs, and all other carbon nanostructures for photoelectrochemical investigations. You are welcome to submit your original research or review articles on the below topics, though are not by any means restricted to these topics so long as your submission concerns inorganic nanomaterials and their photoelectrochemical properties.

The CuO@CuFe2O4 core–shell structure represents a new family of photocatalysts that can be used as photoelectrodes that are able to produce hydrogen under a broad spectrum of visible light. Herein, we report a novel approach for the production of this active film by the thermal conversion of CuFe Prussian Blue Analogues. The outstanding photoelectrochemical properties of the photocathodes of CuO@CuFe2O4 were studied with the use of combinatory photo-electrochemical instrumental techniques which proved that the electrodes were stable over the whole water photolysis run under relatively positive potentials. Their outstanding performance was explained by the coupling of two charge transfer mechanisms occurring in core–shell architectures. Full article

Low-cost and simple methods are constantly chased in order to produce less expensive lithium-ion batteries (LIBs) while possibly increasing the energy and power density as well as the volumetric capacity in order to boost a rapid decarbonization of the transport sector. Li alloys and tin-carbon composites are promising candidates as anode materials for LIBs both in terms of capacity and cycle life. In the present paper, electrospinning was employed in the preparation of Sn/SnOx@C composites, where tin and tin oxides were homogeneously dispersed in a carbonaceous matrix of carbon nanofibers. The resulting self-standing and light electrode showed a greatly enhanced performance compared to a conventional electrode based on the same starting materials that are simply mixed to obtain a slurry then deposited on a Cu foil. Fast kinetics were achieved with more than 90% of the reaction that resulted being surface-controlled, and stable capacities of about 300 mAh/g over 500 cycles were obtained at a current density of 0.5 A/g.
