Special Issue Information

Dear Colleagues,

This Special Issue presents a curated collection of original research articles, reviews, and perspectives focused on the development, characterization, and application of nanomaterials and electrochemical technologies to address the global challenge of achieving sustainable energy. Nanomaterials include 1D, 2D, and 3D materials with one or more dimension below 100 nm, as well as nanostructured materials. The articles presented in this Special Issue explore innovative approaches to enhancing the performance, efficiency, scalability, and environmental impact of energy-storage and -conversion systems by including nanoscale and nanostructured materials in electrochemical systems and processes. Topics include the synthesis and characterization of nanomaterials and their applications in batteries, fuel cells, electrochemical capacitors, and (photo)electrocatalysis; energy harvesting; bioinspired and biomass-derived nanomaterials; and carbon-negative nanomaterials and processes.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences 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 2400 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.

This study investigates the impact of acetone on the electrochemical behaviour of 3D nickel foam electrodes in 0.1 M NaOH solution, with respect to the kinetics of alkaline water electrolysis (hydrogen and oxygen evolution reactions: HER and OER, respectively). Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Tafel polarisation techniques were employed to investigate the kinetics of these processes for (CH3)2C=O concentrations ranging from 1.0 × 10−5 to 0.1 M. The fundamental conclusions of this work are related to the fact that acetone, at moderate concentrations, was found to significantly facilitate the kinetics of both the HER and the OER processes, when examined on unmodified Ni foam electrodes. Conversely, the presence of acetone in working electrolyte for a Ru-activated nickel foam electrode resulted in a radical inhibition of the HER kinetics. The above is strongly believed to be associated with an electrode surface poisoning effect, in relation to the Ru sites’ blockage by an extensive, flat/side-on coordination of adsorbed acetone molecules. Interestingly, in the presence of Ru, acetone had practically no effect on the recorded OER rates. The above indicates that some organic additives (e.g., acetone) might exhibit significant, although strongly catalyst-dependent, opportunities for facilitation of the industrial alkaline water electrolysis process.

This study reports the room-temperature, one-pot, rapid alkalide reduction synthesis of germanium metal nanoparticles on multilayer graphene nanoshells (MGNSs) at a high yield (97%), as well as their electrochemical performance as a Li-ion battery anode. Ge metal’s theoretical gravimetric capacity is second only, and its volumetric capacity nearly equal, to that of Si which possesses the highest capacities of any lithium alloying metal. An MGNS is a carbon net-negative material composed of nested graphene sheets with high surface area, good electrical conductivity and excellent electrochemical stability. When cycling from 1.5 to 0.02 V vs. Li, a stable capacity of ~750 mAh/g Ge/MGNS composite electrode was obtained with an average capacity fade of 0.014% per cycle, maintaining 85% of the original capacity after 600 cycles.
