Special Issue Information

Dear Colleagues,

Increasingly serious environmental concerns have stimulated significant efforts to develop green and efficient energy conversion and waste treatment technologies, among which electrocatalysis has been considered as a clean and renewable one. The development of high-efficiency and durable electrocatalysts to promote electrochemical reactions is highly desirable.

With this Special Issue of Nanomaterials titled “Functional Nanostructured Electro/Photocatalysts for Energy Conversion and Environmental Treatment”, we encourage authors to share their developments in the design, characterization, and application of nanostructured electro/photocatalysts for various electro/photocatalytic reactions, including but not limited to biomass upgrading and the reactions of hydrogen evolution, oxygen evolution, CO2 reduction, N2 reduction/oxidation, NO3/NO2/NO reduction, chlorine evolution, and O2 reduction, mainly focusing on the production of renewable energy and valuable chemicals and wastewater treatment.

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.

The activation of PMS to produce active species is an attractive technique for antibiotic degradation but is restricted to the low reaction kinetics and high costs. In this work, a cobalt-based catalyst was prepared by in situ electrodeposition to enhance the electrically activated PMS process for the degradation of antibiotics. Almost 100% of pefloxacin (PFX) was removed within 10 min by employing Co(OH)2 as the catalyst in the electrically activated peroxymonosulfate (PMS) process, and the reaction kinetic constant reached 0.52 min−1. The redox processes of Co2+ and Co3+ in Co(OH)2 catalysts were considered to be the main pathways for PMS activation, in which 1O2 was the main active species. Furthermore, this strategy could also achieve excellent degradation efficiency for other organic pollutants. This study provides an effective and low-cost strategy with no secondary pollution for pollutant degradation. Full article
