Special Issue Information
Recently, transition metal nanoparticles have been of considerable interest as catalysts in organic and inorganic transformations. Being small in size is expected to increase the nanoparticle surface tension. This makes surface atoms very active. In many cases, the inherent advantages of heterogeneous catalysts, such as the ease of product separation and catalyst recycling, are observed. However, the activity and selectivity of catalyst nanoparticles are strongly dependent on their size, shape, surface structure, and their bulk and surface composition. A large number of review articles provide extensive coverage of the subject. Moreover, the preparation, characterization, and mechanism of formation of transition metal nanoparticles have been extensively reviewed.
Homogeneous nanosized catalysts are already well known that exhibit better catalytic activity than heterogeneous catalysts because of easy solubility in reaction media and access to all catalytic sites. However, these homogeneous catalysts are rarely separated and recovered from the reaction systems efficiently by centrifugation methods and traditional filtration. For example, palladium nanoparticles have had problems in the reuse of catalysts and aggregation, thereby resulting in a decrease of catalytic activity. Catalysts in a distinct phase with respect to the reaction medium account for the major advantage of the heterogeneous catalysts over homogeneous catalysts, as it makes the separation and reutilization of heterogeneous catalysts simple and cheap compared to homogeneous catalysts. To overcome the drawback of these homogeneous catalysis problems, many efforts have been made to achieve the immobilization of a homogeneous nanocatalyst onto various insoluble support, activated carbon, polymer, alumina, porous silica materials with high surface area, zeolites, layered double hydroxides and magnetic nanoparticles. Recovering and recycling catalysts that are quite expensive result in positive effects from an economic and environmental point of view. The recognition of these limitations of homogeneous catalysts resulted in attempts to heterogenize homogeneous catalysts. However, a major drawback of heterogenized catalysts is the leaching of the catalyst during its use and recycling, leading to deactivation. A goal of catalyst research is to combine the advantages of both homogeneous (activity and selectivity) and heterogeneous catalytic systems (recycling catalyst), resulting in overcoming these problems.
All experimental works falling within the scope of this Special Issue, including original research papers, short communications, review articles, and perspective articles, are invited for submission.
This Special Issue on the “Synthesis and Application of Novel Nanocatalysts” aims to curate novel advances in the development and application of nanocatalysts to address longstanding challenges in heterogeneous catalysts. Topics include, but are not limited to:
