Special Issue Information

Dear Colleagues,

This Special Issue, focuses on recent advances in electrochemical reaction technologies with an emphasis on molecular-level understanding and innovation. We welcome contributions that explore electrochemical systems such as supercapacitors, batteries and sensors, highlighting new materials and interface phenomena. Studies involving electrocatalysis, charge storage, redox processes, and the design of functional nanomaterials are particularly encouraged. This issue aims to showcase cutting-edge research that supports the development of efficient and high-performance electrochemical technologies for applications in energy storage, environmental monitoring, and biosensing.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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 research demonstrates, for the first time, the integration of aero-titania material in sensor devices. An innovative approach for the practical application of aero-titania (aero-TiO2) materials in photodetectors and the characterization under ultraviolet irradiation was assessed. The fabrication of aero-materials was carried out through the atomic layer deposition (ALD) of titanium dioxide ultrathin layers on a sacrificial network consisting of zinc oxide micro-tetrapods. This process was followed by a selective etching of the sacrificial ZnO template and formation of aero-titania hollow micro-tetrapods. The obtained material has been characterized using UV-Vis spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD) analysis. The development of photodetectors was achieved through the sequential spin-coating deposition of aero-TiO2 onto an interdigitated ceramic electrode. The obtained results show that, for high-intensity ultraviolet, the maximum sensitivity was reached for the two-deposited-layer aero-TiO2 sensor at about 23, since for the low-intensity UV the highest sensitivity was recorded for the one-deposited-layer aero-TiO2 sensor at about 12. In terms of the responsivity, the highest response was obtained for the one-deposited-layer aero-TiO2 sensor under low-intensity illumination, reaching about 1.23 × 10−4 A W−1 cm−2. Thus, the aero-TiO2 structure demonstrates the practical viability and application potential of this emerging class of materials in advanced sensing technologies. Full article
