Special Issue Information

Dear Colleagues,

The accelerating shift towards sustainable energy solutions has heightened the need for advanced energy storage and conversion systems. Central to these developments is the field of electrochemical catalysis, which governs critical processes such as water splitting and carbon dioxide reduction. These processes are essential for generating clean fuels and storing energy efficiently. However, the effectiveness of these systems hinges on the design and performance of catalysts, which often face challenges related to activity, selectivity, and stability under operational conditions. In parallel, energy storage technologies, including batteries and supercapacitors, are rapidly evolving. The development of high-performance materials has the potential to enhance energy density, charge–discharge efficiency, and lifecycle.

Advanced coatings, including metal and alloy films, play a vital role in enhancing the performance of electrochemical catalysts by acting as barriers against corrosion and oxidation. These coatings also improve conductivity and facilitate better interaction between reactants and catalytic surfaces. Additionally, advancements in coatings can significantly impact energy storage technologies, including batteries and supercapacitors, by optimizing material interfaces and enhancing charge–discharge efficiency.

We are pleased to invite you to submit your research to this Special Issue. The scope of this Special Issue covers a range of topics related to coatings in electrochemical catalysis and energy storage materials such as those listed below:

  • Novel catalysts for electrochemical reactions, such as water splitting and CO2;
  • Advanced energy storage materials, including batteries, supercapacitors, and hydrogen storage systems;
  • Surface modification techniques that enhance catalyst performance through improved stability and reactivity;
  • Advanced coatings for key components in electrochemical catalysis and energy storage system, like bipolar plates, gas diffusion layers, current collectors, etc.;
  • Fundamental understanding of electrochemical processes and mechanisms.

This Special Issue aims to showcase the latest research in coatings, electrochemical catalysis, and energy storage. We seek contributions that explore innovative materials, surface modification techniques, and electrochemical mechanisms that address current limitations and push the frontiers of energy technology.

We look forward to receiving your contributions.

The urea electro-oxidation reaction (UOR) is emerging as a new energy conversion technology and a promising method for alleviating water eutrophication problems. However, a rationally designed structure of the electrode materials is urgently required to achieve high UOR performance. Herein, P-doped MOF-derived Co3O4 nanowire arrays grown on nickel foam (P-Co3O4/NF) are successfully synthesized via the growth of Co-MOF and subsequent calcination followed by phosphorization treatment. Owing to the optimized electronic structure, the as-prepared P-Co3O4/NF composite exhibits much higher UOR electrocatalytic performance than the undoped Co3O4/NF sample. Beyond this, the meticulous structure of the one-dimensional nanowire arrays and the three-dimensional skeleton structure of nickel foam contribute to the enhanced electrocatalytic activity and stability toward UOR. As a result, the P-Co3O4/NF composite displays a low overpotential of 1.419 V vs. RHE at 50 mA cm−2, a small Tafel slope of 82 mV dec−1, as well as favorable long-term stability over 65,000 s in 1.0 M KOH with 1.0 M urea. This work opens a new avenue in designing non-precious electrocatalysts for high-performance urea electro-oxidation reactions. Full article
