Special Issue Information

Dear Colleagues,

The vision of reaching "carbon peaking and carbon neutrality" has been regarded as one of the most pressing global concerns, and efficient energy conversion and storage technology is a key technology to achieve a breakthrough in carbon-neutral technologies, such as batteries, capacitors, electrocatalysis, etc. To this end, this Special Issue, entitled “Featured Papers in Electrochemistry and Electrocatalysis in China”, aims to highlight the recent progress and development in design and characterization of traditional and innovative materials and new insights into these materials in energy storage and conversion.

The detailed research areas include the following:

  • Developing energy conversion and storage systems with high energy density, high power density, high stability and high safety.
  • Design, preparation and application of electrocatalysts with high activity, high selectivity and long lifetime for specific reactions.
  • New concepts and insights into energy storage or conversion mechanisms for electrochemistry and electrocatalysis.

The research works as well as review articles focusing on electrochemistry and electrocatalysis are especially welcomed. We hope this Special Issue will popularize the applications of electrochemistry and electrocatalysis techniques in energy conversion and storage studies and furnish important inspiration to researchers for the rational design of the new generation of energy conversion and storage materials.

Rational design and construction of cost–effective electrocatalysts for efficient hydrogen production has attracted extensive research attention worldwide. Herein, we report the construction of a transition metal selenide/carbon composite catalyst featuring uniform NiSe nanoparticles anchored to single Ni atom doped porous carbon structure (NiSe/Ni–N–C) via a facile one–pot pyrolysis of low–cost solid mixtures. NiSe/Ni–N–C exhibits remarkable catalytic performance towards hydrogen evolution reaction (HER) in 1.0 M KOH, requiring a low overpotential of 146 mV to reach a current density of 10 mA cm−2. The unique carbon layer encapsulation derived from the enwrapping of fluid catalytic cracking slurry further renders NiSe/Ni–N–C excellent for long–term durability in electrolyte corrosion and nanostructure aggregation. This work paves the way for the design and synthesis of highly efficient composite HER electrocatalysts. Full article

The effects of the electrochemical oxygen reduction reaction (ORR) on the surface of single-phase perovskite cathodes are well understood, but its potential for use in a complex system consisting of different material types is unexplored. Herein, we report how BaCO3 nanoparticles-modified La0.6Sr0.4Co0.2Fe0.8O3-δ-Gd0.2Ce0.8O2-δ (LSCF–GDC)-composite cathodes improved the electrochemical oxygen reduction kinetics for high-performing ceramic fuel cells. Both X-ray diffraction (XRD) and thermogravimetric analysis (TGA) studies reveal that BaCO3 is stable, and that it does not show any solid-state reaction with LSCF–GDC at SOFCs’ required operating temperature. The electrochemical conductivity relaxation (ECR) study reveals that during the infiltration of BaCO3 nanoparticles into LSCF–GDC, the surface exchange kinetics (Kchem) are enhanced up to a factor of 26.73. The maximum power density of the NiO-YSZ anode-support cell is increased from 1.08 to 1.48 W/cm2 via surface modification at 750 °C. The modified cathode also shows an ultralow polarization resistance (Rp) of 0.027 Ω.cm2, which is ~4.4 times lower than that of the bare cathode (~0.12 Ω.cm2) at 750 °C. Such enhancement can be attributed to the accelerated oxygen surface exchange process, possibly through promoting the dissociation of oxygen molecules via the infiltration of BaCO3 nanoparticles. The density functional theory (DFT) illustrates the interaction mechanism between oxygen molecules and the BaCO3 surface. Full article
