Special Issue Information
Dear Colleagues,
Increasing global environmental pollution and the energy crisis are two key challenges we are facing, and energy conversion and renewable technologies with less toxic emissions are highly desirable to achieve a sustainable energy future. Recently, 2D materials have been suggested as promising substrates for the purpose of catalytic applications due to them having high symmetry; the material symmetry can directly determine the possible active site position. Moreover, there are various types of surface defects in 2D nanomaterials, including surface atomic mismatch, surface polarization, surface amorphization, surface doping and impurity adsorption, surface vacancies, and composite vacancies. These defects will reduce the symmetry of 2D materials, and have an important impact on their electronic structure, spectral absorption, the excitation, migration, and recombination of photogenerated electron holes, affecting their catalytic performance. Therefore, the symmetry of 2D materials provides an additional dimension for understanding and regulating catalytic performance.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Symmetry is an international peer-reviewed open access monthly 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.
