Special Issue Information

Dear Colleagues,

Nanostructured materials, including organic, inorganic and hybrid materials, are commonly defined as materials with at least one dimension that fall into the range of nanometers. Owning to their high specific surface area and morphological/compositional flexibility, the synthesis and application of nanostructured materials has experienced tremendous development over the past few decades, demonstrating distinct properties across various fields. In heterogeneous catalysis, specifically, nanostructured catalysts have not only demonstrated high catalytic activity comparable to homogeneous catalysts but also unique catalytic selectivity and stability surpassing their bulk counterparts. Moreover, nanostructured materials (graphene, MOFs, COFs, zeolites, perovskites porous silica, etc.) have served as novel catalysts or catalyst supports to promote milestone breakthroughs in key catalysis reactions like water splitting, CO2 reduction, ammonia synthesis and so on. Exploring new design and synthesis protocols toward advanced nanostructured catalysts, while revealing fundamental reaction mechanisms associated with their structures, is of great significance to both academia and industries.

This Special Issue aims to call for papers related to the design, synthesis and catalytic applications of nanostructured catalysts, preferentially with an emphasis on their unique structure–property correlations. We welcome outstanding original research articles and reviews in related fields to be submitted to the journal before the submission deadline.

I look forward to receiving your contributions.

Perovskites exhibit catalytic properties on the oxygen evolution reaction (OER) in water electrolysis. Elemental doping by specific preparation methods is a good strategy to obtain highly catalytical active perovskite catalysts. In this work, La0.5Sr0.5Co1−xNixO3−δ perovskite materials doped with different ratios of nickel were successfully synthesized by the sol-gel method. The electrochemical measurement results show that for OER in 1 M KOH solution, La0.5Sr0.5Co0.8Ni0.2O3−δ prepared by the sol-gel method requires only a low overpotential of 213 mV to reach 10 mA cm−2, which is significantly lower than that of La0.5Sr0.5Co0.8Ni0.2O3−δ prepared by the hydrothermal method for the increasing about 45.24% (389 mV at 10 mA cm−2). In addition, La0.5Sr0.5Co0.8Ni0.2O3−δ by the sol-gel method can be kept stable in an alkaline medium tested for 30 h without degradation. This indicates that the prepared La0.5Sr0.5Co0.8Ni0.2O3−δ has better OER performance. The X-ray diffraction (XRD) results show that SrCO3 is the main phase formed, which is a disadvantage of this method. The performance improvement may be affected by the carbonate phase. The scanning electron microscopy (SEM) results show that layer structured La0.5Sr0.5Co0.8Ni0.2O3−δ by the sol-gel method has more surface pores with a pore diameter of about 0.362 μm than spherical granular structured La0.5Sr0.5Co0.8Ni0.2O3−δ by the hydrothermal method. X-ray photoelectronic spectroscopy (XPS) results reveal that the crystal lattice of La0.5Sr0.5Co0.8Ni0.2O3−δ by nickel doping is lengthened, and the electronic configuration of Co is also changed by the sol-gel preparation process. The improved electrocatalytic performance of La0.5Sr0.5Co0.8Ni0.2O3−δ may be attributed to the pore structure formed providing more active sites during the sol-gel process and the improved oxygen mobility with Ni doping by the sol-gel method. The doping strategy using the sol-gel method provides valuable insights for optimizing perovskite catalytic properties. Full article

Nanostructured materials have garnered significant attention for their unique properties, such as the high surface area and enhanced reactivity, making them ideal for electrocatalysis. Among these, perovskite oxides, with compositional and structural flexibility, stand out for their remarkable catalytic performance in energy conversion and storage technologies. Their diverse composition and tunable electronic structures make them promising candidates for key electrochemical reactions, including the oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and carbon dioxide reduction (CO2RR). Nanostructured perovskites offer advantages such as high intrinsic activity and enhanced mass/charge transport, which are crucial for improving electrocatalytic performance. In view of the rapid development of nanostructured perovskites over past few decades, this review aims to provide a detailed evaluation of their synthesis methods, including the templating (soft, hard, colloidal), hydrothermal treatments, electrospinning, and deposition approaches. In addition, in-depth evaluations of the fundamentals, synthetic strategies, and applications of nanostructured perovskite oxides for OER, HER, and CO2RR are highlighted. While progress has been made, further research is needed to expand the synthetic methods to create more complex perovskite structures and improve the mass-specific activity and stability. This review offers insights into the potential of nanostructured perovskite oxides in electrocatalysis and provides potential perspectives for the ongoing research endeavor on the nanostructural engineering of perovskites.
