Special Issue Information

Dear Colleagues,

We warmly invite your contributions to the Special Issue titled “Nanostructured Catalysts for Emerging Electrochemical Technologies.” This collection aims to showcase cutting-edge research on nanostructured catalysts that drive innovation in electrochemical energy conversion, storage, and environmental applications.

Electrochemical technologies are pivotal in addressing global energy and environmental challenges. Nanostructured catalysts, with their high surface area and tunable properties, offer significant advantages in enhancing electrochemical performance. This Special Issue will focus on recent advancements in the design, synthesis, and application of these catalysts.

Key Areas of Interest:

  • Energy Conversion: Nanostructured catalysts for ORR, HER, CO2RR, and other electrochemical reactions in fuel cells and electrolyzers.
  • Energy Storage: Advanced nanostructured materials for lithium-ion batteries, sodium-ion batteries, and metal–air batteries.
  • Environmental Applications: Nanostructured catalysts for electrochemical water treatment, air purification, and degradation of environmental pollutants.
  • Characterization Techniques: In situ and operando studies to elucidate the behavior of nanostructured catalysts during electrochemical processes.
  • Synthesis Methods: Novel and sustainable synthesis routes for creating nanostructured catalysts with controlled properties.
  • Cross-Disciplinary Approaches: Integration of nanostructured catalysts with materials science, chemistry, and engineering to address complex challenges.

We welcome original research articles and comprehensive reviews that provide new insights and push the boundaries of current knowledge in this field. Your contributions will help advance the understanding and application of nanostructured catalysts in emerging electrochemical technologies.

Developing high-activity and high-durability Pd-based electrocatalysts is an important strategy to promote their commercial application. Herein, a smaller particle size and ultrathin sheet-like PdCu alloy metallene (PdCuene) were successfully prepared by using a one-pot wet chemistry method for FAOR. Experimental measurements indicated that the introduction Cu into Pd lattice induces a significant compressive strain effect through lattice mismatch between Pd and Cu, and the strain effect optimizes the electronic structure of Pd, as well as the high electrochemical surface area, increased exposure of active sites, and appropriate lattice strain have been demonstrated as factors that influence the enhancement of intrinsic activity and the acceleration of kinetics, thereby improving FAOR performance. Moreover, the stronger lattice strain of 0.85% would facilitate surface adsorption and dissociation of formic acid. Specifically, the optimized PdCuene exhibits enhanced mass activity and specific activity with current densities of 2.31 A mgPd−1 and 4.09 mA cm−2, respectively, which transcend the activities of Pd metallene (1.44 A mgPd−1 and 2.73 mA cm−2) and commercial Pd/C (0.6 A mgPd−1 and 1.53 mA cm−2). Meanwhile, PdCuene displayed obvious enhanced durability. The work provides an approach to modulate the lattice strain engineering, which represents a highly promising strategy for designing efficient FAOR electrocatalysts. Full article
