Nanostructured Photocatalytic and Electrocatalytic Materials for Advanced Sensor Technologies

Dear Colleagues,

Emerging nanostructured materials have garnered substantial attention as multifunctional platforms capable of addressing the escalating environmental, energy, and sensing challenges in the modern world. These advanced photocatalytic, electrocatalytic, and sensor-responsive systems, composed of hybrid nanostructures, offer tunable physicochemical properties that pointedly expand catalytic efficiency and long-term stability. In environmental, energy, and sensor-related applications, nanostructures integrating metal-oxides, polymers, carbon-based materials, MOFs, and MXenes could perform well when applied to environmental, energy storage, and next-generation sensor technologies due to their robust surface characteristics, competent charge transfer pathways, and excellent chemical stability. These effective nanostructures exhibit potential functionalities across photocatalytic and electrocatalytic wastewater remediation, hydrogen/oxygen evolution, CO₂ reduction, environmental sensing, photo/electrochemical sensors, and various biological applications. Current research highlights the need for sustainable nanomaterials that integrate functional design for advanced catalytic engineering to accelerate real-world innovation and expand smart sensor interfaces and high-performance energy-harvesting sensors. This Special Issue focuses on the effective design, development, and applications of novel nanostructured materials that can drive future progress in sustainable environmental, energy, and sensing technologies.

We invite researchers to contribute innovative, original research articles and comprehensive reviews. We hope that this Special Issue will offer pioneering insights and practical solutions addressing sustainable environmental, energy, and sensor systems.

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