Nanomaterials for Advanced Oxidation and Photocatalytic Degradation

Dear Colleagues,

Over the years, a wide range of nanomaterials have been developed as catalysts for use in several variations of advanced oxidation processes (AOPs). Though significant progress has been made in transitioning from traditional UV-light-activated catalysts to less energy-intensive, visible-light-activated photocatalysis, improvements in material design for various applications are still required before commercialization of the technology. The use of nanostructures in newly developed nanotechnology can significantly enhance band gap tailoring, resulting in reduced electron–hole recombination, enhanced transfer of charges, and plasmonic enhancement, among other attributes that promote visible light activation. Catalytic wet peroxide oxidation (CWPO), is another AOP that has made use of nanotechnology to alleviate some of the problems associated with the classical Fenton reaction. This technology uses solid metal-bearing nanomaterials in place of soluble metal salts, resulting in reduced metal leaching and sludge formation. These technologies have been used in numerous applications; however, this Special Issue will focus on presenting comprehensive research outlining progress on the application of nanomaterials as catalysts for advanced oxidation and photocatalytic degradation of environmental remediation applications.

We invite contributions from leading groups in the field with the aim of giving a balanced view of the current state of the art in this discipline. Contributions should be in the form of original research articles and review articles. Potential topics include, but are not limited to:

• Synthesis and application of photocatalysts in environmental remediation;
• Physical and chemical characterizations of photocatalysts;
• Catalytic wet peroxide oxidation and modified Fenton’s reactions;
• Functionalization procedures and surface modifications of photocatalysts;
• Photocatalysis reaction mechanisms;
• Photocatalytic degradation kinetics and modeling;
• Visible-light-active photocatlysts materials;
• Activity and stability studies;
• Environmental safety;
• Modern trends in environmental remediation and protection.

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.
