Special Issue Information

Dear Colleagues,

Multicomponent catalysts are promising catalytic materials that combine multiple elements, phases, or microstructures. The controlled combination of different components in a material can integrate the functionalities associated with each component, allowing the material to catalyze complex reactions that involve multiple steps. In addition, the synergistic electronic interaction between the constituent components has shown the potential to improve the catalyst activity as well as the reaction selectivity. All these characteristics provide rich avenues to tune the chemisorption behavior and catalytic properties of multicomponent materials. Notably, recent developments in the synthetic methodologies of multicomponent nanomaterials, such as phase-separated heterostructures and high-entropy alloys, have enabled tremendous new combinations as well as new possibilities, which have led to an outbreak in the study of multicomponent nanocatalysts.

In this Special Issue, we will bring together the latest advances related to multicomponent catalytic materials. The topics include, but are not limited to, the design, synthesis, characterization, and modeling of multicomponent materials and their applications in thermal catalysis, electrocatalysis, photocatalysis, and other catalytic processes. Original research articles and communications within the theme of this Special Issue are all welcome.

This work focuses on the comparison of H2 evolution in the hydrolysis of boron-containing hydrides (NaBH4, NH3BH3, and (CH2NH2BH3)2) over the Co metal catalyst and the Co3O4-based catalysts. The Co3O4 catalysts were activated in the reaction medium, and a small amount of CuO was added to activate Co3O4 under the action of weaker reducers (NH3BH3, (CH2NH2BH3)2). The high activity of Co3O4 has been previously associated with its reduced states (nanosized CoBn). The performed DFT modeling shows that activating water on the metal-like surface requires overcoming a higher energy barrier compared to hydride activation. The novelty of this study lies in its focus on understanding the impact of the remaining cobalt oxide phase. The XRD, TPR H2, TEM, Raman, and ATR FTIR confirm the formation of oxygen vacancies in the Co3O4 structure in the reaction medium, which increases the amount of adsorbed water. The kinetic isotopic effect measurements in D2O, as well as DFT modeling, reveal differences in water activation between Co and Co3O4-based catalysts. It can be assumed that the oxide phase serves not only as a precursor and support for the reduced nanosized cobalt active component but also as a key catalyst component that improves water activation.

The intermetallic PtBi/MgO/Mg monolithic catalyst was first prepared using non-equilibrium plasma electrolytic oxidation (PEO) technology. Spherical aberration-corrected transmission electron microscope (ACTEM) observation confirms the successful synthesis of the PtBi intermetallic structure. The efficiency of PtBi/Mg/MgO catalysts in catalyzing the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in the presence of NaBH4 was demonstrated. The activity factor for the catalyst is 31.8 s−1 g−1, which is much higher than reported values. In addition, the resultant catalyst also exhibits excellent catalytic activity in the organic pollutant reaction of p-nitrobenzoic acid (p-NBA) and methyl orange (MO). Moreover, benefiting from ordered atomic structures and the half-embedded PtBi nanoparticles (NPs), the catalyst demonstrates excellent stability and reproducibility in the degradation of 4-NP. This study provides an example of a simple method for the preparation of intermetallic structures as catalysts for organic pollutant degradation. Full article
