Special Issue Information
Dear Colleagues,
Nanomaterials have become increasingly important in photoelectrochemical and electrochemical applications due to their unique properties, such as a high surface area, tuneable electronic and optical properties, and efficient charge transport. In photoelectrochemical applications, nanomaterials have been used as photoanodes and photocathodes to convert solar energy into chemical energy. For example, semiconducting nanomaterials, such as titanium dioxide and zinc oxide, have been used as photoanodes in dye-sensitized solar cells and water splitting reactions. In addition, plasmonic nanomaterials, such as gold and silver nanoparticles, have been used to enhance light absorption in photoelectrochemical systems.
In electrochemical applications, nanomaterials have been used as catalysts to facilitate chemical reactions with high efficiency and selectivity. For example, metal nanomaterials, such as platinum and palladium nanoparticles, have been used as catalysts in fuel cells and electrochemical sensors. Carbon-based nanomaterials, such as graphene and carbon nanotubes, have also been used as catalysts in electrochemical reactions due to their high surface area and unique electronic properties.
Moreover, nanomaterials have also been used as electrode materials in supercapacitors and batteries. For example, nanoscale metal oxides, such as nickel oxide and manganese oxide, have been used as electrode materials in supercapacitors due to their high specific capacitance and good cycling stability. Lithium-ion batteries have also been improved by using nanomaterials, such as silicon nanoparticles and metal oxide nanowires, as anodes, which can increase the energy density and cycling stability of the battery.
Overall, nanomaterials have demonstrated great potential in a wide range of photoelectrochemical and electrochemical applications, and ongoing research is expected to lead to further improvements in these fields.

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. Nanomaterials 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 2900 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.
