Special Issue Information

Dear Colleagues,

The current Special Issue titled “Advances in Nanomaterials for Homogeneous/Heterogeneous Catalysis” focuses on innovative advancements in the design of nanomaterials and their significant influence on heterogeneous catalysis. It highlights the synthesis and structural refinement of nanoscale materials, including nanostructured oxides, metal chalcogenides, and hybrid systems, to improve catalytic efficiency in energy conversion, storage, and environmental applications. The Issue underscores the dynamic interactions occurring at nanoscale catalytic interfaces, leveraging unique size-dependent characteristics and optimizing electronic and structural attributes to achieve enhanced catalytic activity. These developments are particularly relevant to essential applications such as water splitting, CO2 conversion, and the production of green hydrogen, thereby propelling the advancement of next-generation catalytic systems that exhibit improved scalability and durability, making them suitable for large-scale industrial applications and sustainable energy solutions.

Aside from the increasing demand for efficient and sustainable catalytic processes, this Issue explores the advanced synthesis methodologies and structural innovations that facilitate exceptional control over catalytic activities. Prominent topics include surface and interface engineering, manipulating electronic structures, and the development of multifunctional nanocatalysts.

This Special Issue covers diverse cutting-edge research areas, including (but not limited to) the following:

  • Energy Conversion: The development of advanced nanocatalysts for electrocatalytic/photocatalytic water splitting (PEC), reduction of carbon dioxide to fuels, and the fixation of nitrogen for ammonia synthesis is directed towards the promotion of sustainable energy generation and storage;
  • Environmental Remediation: The application of nanomaterials in catalytic processes is being explored to tackle environmental issues, including the degradation of pollutants from wastewater, the capture of carbon dioxide, and the production of green hydrogen.
  • Sustainable Chemical Transformations: Catalytic processes that are environmentally friendly and energy-efficient are being investigated to diminish dependence on non-renewable resources and to reduce waste generation.
  • Industrial Catalysis: The scaling up of high-performance nanocatalysts for various industrial applications, such as petrochemical refining, biomass conversion, and the synthesis of fine chemicals, is being prioritized with a focus on sustainability and energy efficiency.
  • Design of homogeneous/heterogeneous catalysts using inorganic nanomaterials with high activity, selectivity, and stability.

In this article, Pt-SnxOy hybrid nanoparticles encaged in porous silica nanospheres (Pt-SnxOy@PSNs) were prepared by using 1-dodecanethiol (C12-SH) as a coordination agent to confine Pt and Sn ions in a microemulsion system, which is formed by cetyltrimethylammonium bromide (CTAB) and C12-SH as co-surfactants in water. Compared with Pt@PSNs, when different molar ratios of SnxOy were introduced into Pt@PSNs to form Pt-SnxOy@PSNs, the catalytic efficiency of 4-nitrophenol (4-NP) reduction with NaBH4 can be significantly enhanced. At molar ratios of 4-NP/Pt of 150/1, the 4-NP conversion reached 100% over Pt-SnxOy@PSNs with Pt/Sn molar ratios of 1/0.75 in 8 min. This catalytic performance showed a slight decrease after six reaction cycles. This enhanced catalytic efficiency can be ascribed to the synergistic effect between Pt and SnxOy, and the protection of porous silica nanostructures can effectively improve the stability of the catalyst.

One of the main challenges in environmental remediation is the creation of stable and effective photocatalysts to eliminate organic contaminants when exposed to visible light. For the degradation of N-chloropiperidine, a persistent organic pollutant with multiple dangerous issues, we provide the synthesis, characterization, and photocatalytic evaluation of a Ni/NiO-incorporating carbon nitride (Ni/NiO-C3N4) composite in this work. The Ni/NiO-C3N4 photocatalyst was created by a single step of thermally polymerizing nickel nitrate and melamine. Four samples are ranged in Ni concentration from 0% to 10%. The coexistence of the Ni and NiO phases was confirmed by structural and morphological analyses using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR). UV−Vis diffuse reflectance spectroscopy (DRS) also demonstrated an enhanced capacity to absorb visible light. A study of photocatalytic performance under visible light illumination showed that the Ni/NiO-C3N4 composite degraded N-chloropiperidine at a much faster rate than either pure carbon nitride (0.0231 min−1), with a first-order rate constant of 0.0456 min−1. The reaction rate nearly quadrupled when 10% Ni was added to the C3N4 matrix. Furthermore, the Ni/NiO-C3N4 composite’s photocatalytic activity performed better than its counterparts Ni-C3N4 (0.0315 min−1) and NiO-C3N4 (0.0386 min−1). The synergistic interaction between Ni and NiO, which promotes effective charge separation and lowers electron–hole recombination, is responsible for the higher activity of Ni/NiO-C3N4, increasing the production of reactive oxygen species. Furthermore, reusability experiments conducted over four successive cycles showed a slight decrease in activity, indicating the prepared samples are stable and reusable. Full article
