Special Issue Information

Dear Colleagues,

This Special Issue, “Design and Properties of Functional Nanocatalysts”, focuses on the design of nanoscale functional catalysts with respect to theory, methods and applications, and coincides with the research scopes of environmental and energy catalytic conversion, material science, biocatalytic systems and sustainability. The goals of this Special Issue are to:

  • Develop theoretical foundations and synthetic methods for the design of functional catalysts;
  • Identify the properties of the designed catalysts, such as their morphology, size and electronic structure;
  • Gain insight into the correlation of the structural design of functional materials with their catalytic performance (e.g., photo-, electro- and biocatalytic systems);
  • Develop applications for functional catalysts in the fields of sustainable environmental catalysis (e.g., pollutant removal and adsorption) and clean energy catalysis (e.g., fuel cells).

Other relevant nanomaterials and their applications will also be considered.

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. Crystals 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 2100 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.

Congo red (CR), a highly pigmented anionic dye, is highly toxic and resistant to degradation. The discharge of CR wastewater into the natural environment can lead to ecological destruction and harm to human health. CeO2 as an adsorbent possesses the advantages of excellent acid and alkali resistance, biocompatibility, stable physical and chemical properties, and nontoxic by-products. The impact of Zr doping on the adsorption performance of nano-CeO2 was investigated. XPS and Raman characterisation revealed that Zr doping effectively enhanced the oxygen vacancy ratio at the active sites for CR adsorption on the surface of nano-CeO2. When the doping amount of Zr was 3%, the nanoparticles with the best adsorption properties were obtained, and the adsorption amount of CR at room temperature was as high as 3642.05 mg/g, which was approximately three times the adsorption amount of undoped CeO2. This excellent adsorption property shows good prospects for the removal of anionic dyes from wastewater. Full article
