Special Issue Information

Dear Colleagues,

Nanotechnology and nanomaterials/nanoparticles have already gained a lot of attention for their countless potential applications. They were intensively investigated as diagnostics in biomedicine and environmental technologies, among many others. Researchers’ interest in them is driven by their chemical and structural diversity, low cost, non-toxicity, and high flexibility of preparation methods, enabling their synthesis with high yield, purity, and desirable physicochemical features. These, coupled with tunable surface properties, make them an excellent platform for a broad range of (photo)catalytic, biological, and biomedical applications.

This Special Issue welcomes original contributions based on experimental and/or computational techniques, with the aim of covering the most recent research progress in nanotechnology aspects regarding the application of novel materials (nanoparticles, composites, hybrids, etc.) in environmental catalysis, including photocatalysis, electrocatalysis, (photo)Fenton, and other processes, as well as their application within diagnostics as biosensors.

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. Materials 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 2600 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.

V-doped ZrO2 support materials were synthesized through a hydrothermal method, followed by a deposition–precipitation process to load Au clusters using an H4AuClO4 precursor. This study investigated the impact of vanadium doping on propylene epoxidation over the corresponding Au-supported catalysts. Vanadium incorporation significantly enhanced propylene conversion and promoted acrolein production, leading to reduced propylene oxide selectivity. Propylene epoxidation at higher temperatures accelerated the decomposition of oxygenates into CO2. Vanadium addition to ZrO2 altered the interactions between Au and V-doped ZrO2, thereby modifying the chemical states of Zr, Au, and V and forming surface oxygen vacancies and active oxygen species. These changes defined the catalytic performance of the materials. Full article
