Special Issue Information

Dear Colleagues,

Nanocatalysts, materials with at least one dimension in the nanoscale range (1-100 nm), have revolutionized various fields, including catalysis, energy storage, and environmental remediation. Their unique properties, such as high surface area, quantum size effects, and tunable electronic structures, make them highly efficient catalysts for a wide range of reactions.

The field of nanocatalysis has witnessed significant advancements over the past few decades. Early research focused on synthesizing nanomaterials with controlled size, shape, and composition. More recent studies have delved into understanding the structure-property-performance relationships of nanocatalysts, aiming to design highly active and selective catalysts for specific applications.

This Special Issue aims to highlight the latest advancements in the structural regulation and performance assessment of nanocatalysts. It will cover a broad range of topics, including, but not limited to, the following:

  • Synthesis and Characterization: Novel synthesis strategies for nanocatalysts with precise control over size, shape, composition, and surface properties. Advanced characterization techniques to probe the structure and properties of nanocatalysts at the atomic and molecular levels.
  • Structure-Property Relationships: The correlation between the structural features of nanocatalysts (e.g., size, shape, composition, defects, and surface chemistry) and their catalytic performance.
  • Performance Assessment: Development of advanced techniques for evaluating the catalytic activity, selectivity, and stability of nanocatalysts under various reaction conditions.
  • Theoretical Modeling: Computational modeling and simulations to gain insights into the reaction mechanisms and to predict the performance of nanocatalysts.
  • Applications: The application of nanocatalysts in various fields, such as energy conversion, environmental remediation, fine chemical synthesis, and materials science. 

The field of nanocatalysis is continually evolving, with cutting-edge research focused on the following areas:

  • Single-Atom Catalysts: Developing highly active and selective catalysts by anchoring single metal atoms on support materials.
  • Nanoporous Materials: Utilizing nanoporous materials as supports for nanocatalysts to enhance mass transport and catalytic performance.  
  • Operando Characterization: Employing advanced in situ and operando techniques to study the dynamic behavior of nanocatalysts under reaction conditions.
  • Machine Learning: Leveraging machine learning algorithms to accelerate the discovery and optimization of nanocatalysts.  
  • Green and Sustainable Catalysis: Developing environmentally friendly and sustainable nanocatalysts for various applications.

We invite original research articles, review articles, and communications that contribute to the advancement of nanocatalysis. Potential topics include the following:

  • Synthesis and Characterization: Novel synthesis methods, advanced characterization techniques, and in-depth studies of nanocatalyst structures.
  • Mechanistic Insights: Unraveling the reaction mechanisms of catalytic processes using experimental and theoretical methods.

Significant differences in hydrogen adsorption on amorphous and crystalline gold nanoparticles deposited on highly oriented pyrolytic graphite (HOPG) were revealed. Crystalline nanoparticles were synthesized via the impregnation–precipitation method followed by annealing at 700 K, whereas amorphous ones were obtained using the laser electrodispersion method. The morphology and electronic structure of single nanoparticles were investigated with high spatial resolution using scanning tunneling microscopy and spectroscopy (STM/STS) in ultra-high vacuum both before and after exposure to molecular hydrogen at doses of 400–6000 L. Experiments performed at room temperature showed that the surface coverage by the adsorbate in both cases begins at the Au-HOPG interface, spreads towards the center of the particle, and corresponds to the island growth model. However, amorphous nanoparticles have fewer growth sites at the periphery compared to crystalline ones. The local electronic structure of amorphous nanoparticles is more inhomogeneous compared to crystalline ones, demonstrating variation across different points on the nanoparticle surface. It was shown that dissociative chemisorption of hydrogen takes place on amorphous gold nanoparticles with a size of 4–6 nm. Chemisorption is completely inhibited when the nanoparticle size is reduced to 2 nm or less. Full article

As a widely used catalyst class, transition metal oxides (TMOs) face the challenges of detrimental nanoparticle agglomeration. The newly developing two-dimensional (2D) covalent triazine frameworks (CTFs) offer a promising solution as catalyst supports, capable of yielding composites with excellent dispersibility and synergistic catalytic enhancement. Building on this, and employing a hydroxylation functional modification strategy, this article introduces a binary oxide system to construct a CTF/CuO–NiO composite that exhibits excellent catalytic performance for the thermal decomposition of ammonium perchlorate (AP). Specifically, polyvinyl alcohol (PVA) was first employed to introduce -OH anchoring sites onto the CTF surface. A subsequent co-precipitation yielded a uniform dispersion of CuO–NiO nanoparticles across the functionalized CTF support. DSC analysis revealed that incorporating merely 2 wt% of the CTF/CuO–NiO composite into AP significantly alters its high-temperature decomposition (HTD) peak temperature, shifting it from 404.6 °C to 332.1 °C. This work highlights the construction of a binary oxide system through an effective dispersion strategy to enhance the synergistic catalytic performance of CTF-based composites. Full article

The hydrogen evolution reaction (HER) is a cornerstone of green hydrogen production, yet its efficiency is constrained by the sluggish kinetics of water splitting. High-entropy catalysts (HECs), single-phase materials incorporating multiple principal elements, have emerged as a transformative solution. Their unique attributes including vast compositional flexibility, tunable electronic structures, and synergistic multi-element interactions, enable them to overcome the activity, stability, and cost limitations of conventional catalysts. Despite rapid performance advancements, the rational design of HECs is fundamentally hampered by critical knowledge gaps, particularly in identifying true active sites under operando conditions and predicting long-term stability. This work critically assesses these challenges, systematically summarizing the latest progress in HECs design, synthesis, and structure–activity relationships. By bridging fundamental principles with practical applications, we provide a forward-looking perspective on key research directions. Distinct from recent progress-focused reviews, this work establishes a strategic roadmap by systematically diagnosing seven grand challenges across the science-to-technology pipeline and proposing corresponding countermeasures. This framework aims to guide future research efforts toward the rational design and practical deployments of HECs for practical and cost-effective green hydrogen production. Full article

Methanol Steam Reforming (MSR) is one of the most promising technologies in the hydrogen economy, and copper-based catalysts have become the core materials in this field due to their high activity and low cost. In this paper, we systematically review the design strategies of copper-based catalysts in MSR reactions in recent years, including structure control, component optimization, support effect, and surface modification. We focus on the mechanisms of active site exposure, improvement of anti-sintering ability, and the enhancement of anti-carbon deposition performance. Finally, we summarize the challenges of current research and propose the future development direction. This review aims to provide a reference for subsequent related research through the experience of this paper. Full article
