Special Issue Information

Dear Colleagues,

Diamond is an extremely stable crystalline form of carbon that is a valuable material in many applications due to its unusual physical and chemical properties. For this reason, it has long attracted the attention of scientists and the public. In the last twenty years, conductive-synthetic diamond films have been the subject of applications and fundamental research in several fields of science and engineering. In this context, this Special Issue of Materials is devoted to the latest “Advances in Synthetic Diamond Films”. We call for original research papers with high scientific quality as well as review articles covering topics including but not limited to:

  • Synthesis and characterization of diamond materials;
  • Applications and fundamental research in electrochemistry;
  • Instrumental analysis;
  • Industrial applications;
  • Synthesis of chemicals;
  • Modification of diamond surfaces;
  • Electroanalysis and analytical chemistry applications including pH sensors;
  • Water disinfection;
  • Biosensors and sensing materials;
  • Water and wastewater treatments;
  • Photoelectrocatalysis;
  • Electrochemical production of oxidants, such as active chlorine, ferrate, persulfate and other peroxygen compounds;
  • Electrochemical detectors for liquid chromatography;
  • Micro- and nanosensor arrays for the simultaneous detection of multiple analytes and nanoelectrodes for the in vivo detection of neurotransmitters;
  • Applications in the field of energy including the electroreduction of CO2 and energy storage as well as hydrogen production;
  • Novel applications in organic electrochemistry as well as in medical and theoretical chemistry;
  • Water splitting;
  • Integrated diamond technologies with renewable energies;
  • Waste valorization.

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).

In this study, for the first time, the production of green hydrogen gas (H2) in the cathodic compartment, in concomitance with the electrochemical oxidation (EO) of an aqueous solution containing Calcon dye at the anodic compartment, was studied in a PEM-type electrochemical cell driven by a photovoltaic (PV) energy source. EO of Calcon was carried out on a Nb/BDD anode at different current densities (7.5, 15 and 30 mA cm−2), while a stainless steel (SS) cathode was used for green H2 production. The results of the analysis by UV-vis spectroscopy and total organic carbon (TOC) clearly showed that the electrochemical oxidation (EO) of the Calcon dye after 180 min of electrolysis time by applying 30 mA cm−2 reached up to 90% of degradation and 57% of TOC removal. Meanwhile, under these experimental conditions, a green H2 production greater than 0.9 L was achieved, with a Faradaic efficiency of 98%. The hybrid electrolysis strategy is particularly attractive in the context of a circular economy, as these can be coupled with the use of more complex water matrices to transform organic depollution into an energy resource to produce H2 as a chemical energy carrier.
