Special Issue Information

Dear Colleagues,

Perovskite materials, represented by a formula of ABX3, have attracted considerable attention because of their adjustable structure−composition−property relationships. Therefore, some special advantages can facilitate their scalable use as active components for a variety of applications, such as alleviating the energy crisis and environmental problems.

Here, as the Guest Editor, I would like to invite you to submit your original research articles, reviews or perspective to this Coatings Special Issue entitled “Perovskite Materials: Preparations, Characterizations and Applications”. The goal of this Special Issue includes all aspects of research related to perovskite materials, including theoretical and experimental papers, case studies, and reviews.

We encourage you to submit manuscripts containing scientific findings within the broad fields of perovskite materials.

In particular, topics of interest include but are not limited to:

  • Solid oxide fuel/electrolysis cells, e.g., electrodes, electrolytes and interconnectors;
  • Gas sensors, e.g., sensing electrodes;
  • Hydrogen/oxygen permeation membranes;
  • Deposition method, e.g., plasma spraying, pulsed laser deposition;
  • Thermocatalysis/Electrocatalysis/Photocatalysis, e.g., alkane dehydrogenation, water splitting, CO2 reduction, N2 reduction;
  • Piezoelectric/ferroelectric ceramics;
  • Perovskite solar cells;
  • Additive manufacturing;
  • Experimental testing;
  • Numerical modeling;
  • Any other aspects of perovskite materials.

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. Coatings 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 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.

Abstract
Since the conduction activation energy of a proton is low, proton-conducting solid oxide fuel cells (H-SOFCs) can work at low temperatures (around 600 °C), which is conductive to maintaining the long-term stability of SOFCs. Proton conductor BaCe1-xYxO3-δ is [...] Read more.
Since the conduction activation energy of a proton is low, proton-conducting solid oxide fuel cells (H-SOFCs) can work at low temperatures (around 600 °C), which is conductive to maintaining the long-term stability of SOFCs. Proton conductor BaCe1-xYxO3-δ is the most commonly used electrolyte material for H-SOFCs, which directly affects the performance of SOFCs. For the purpose of realizing the high-performance BaCe0.8Y0.2O3-δ (BCY) proton electrolyte materials for SOFC, the effect of different contents of the transition metal oxide NiO on the performance of proton electrolyte BCY was studied. Specifically, BCY-x mol% NiO (named BCY, BCY + 0.5NiO, BCY + 1NiO, BCY + 2NiO, and BCY + 3NiO, when x = 0, 0.5, 1, 2, and 3, respectively) composite electrolyte materials were prepared, and their crystal structures, morphologies, and electrochemical properties were explored. The results showed that NiO could effectively improve the density of BCY prepared at 1400 °C and enhance the proton conductivity of BCY and the performance of BCY-based SOFCs. Among them, the BCY + 2NiO electrolyte had good density and the highest proton conductivity, and the SOFC based on the BCY + 2NiO electrolyte had the best electrochemical performance, indicating that the optimal content of the NiO additive was 2 mol% in this case. The results reported in this work are conductive to the realization of high-performance proton electrolyte materials for the SOFC. Full article
