Two-Dimensional Materials for Photocatalysis and Energy

Dear Colleagues,

Two-dimensional (2D) materials have emerged as a transformative class of materials for energy and environmental technologies due to their unique physicochemical properties, large surface-to-volume ratio, tunable band structures, and superior charge transport characteristics. This Special Issue focuses on the recent advances in the design, synthesis, and application of 2D materials—such as MXenes, transition metal dichalcogenides (TMDs), graphitic carbon nitrides, and beyond—in photocatalytic and energy conversion/storage systems.

This Special Issue aims to provide a comprehensive platform for showcasing the cutting-edge development of 2D optoelectronic materials for clean energy and photocatalysis, and to foster interdisciplinary collaboration in this rapidly growing field.

Topics of interest include, but are not limited to, the following:

• Two-dimensional material-based photocatalysts for solar-driven water splitting and CO₂ reduction
• Heterostructures for enhanced charge separation
• Interfacial engineering for light harvesting
• Two-dimensional materials in batteries, supercapacitors, and thermoelectrics
• Novel synthesis methods of 2D materials
• Advanced spectroscopic and computational methods for elucidating the photocatalytic mechanism

We welcome original research articles and reviews from the community, and we hope this Special Issue will serve as a valuable resource for researchers across materials science, chemistry, physics, and engineering. We also invite readers to explore the diverse contributions that showcase the exciting opportunities of 2D materials in addressing global energy and sustainability challenges.

We look forward to your participation and engagement!

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. 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.
