“…One of these challenges is to get the highest selectivity of a given reaction, such as the partial hydrogenation of bio-based substrates (fatty acid alkyl esters, lignin-derived compounds) thanks to the efficient confinement of the catalytic system (Liu et al 2017;Na Rungsi et al 2021). The synthesis of bimetallic nanoparticles as alloy or core-shell is important for the controlled use of noble metal precursors.…”

Metal nanoparticles, with high surface area to volume ratios and heterogeneous catalytic properties, are a very challenging research area. In the last decades, many efforts have been devoted to the design of supramolecular metal nanoparticles in order to be used in aqueous medium. In catalysis, water is a highly desirable solvent for developing chemical reactions, in accordance with the principles of green chemistry. In this context, the utilization of macrocyclic compounds, in association with transition metal nanoparticles, appears to be a very appealing approach for developing water-dispersible catalytic systems, with high levels of performances and selective molecular recognition abilities. The purpose of this review is to summarize the research done in this field, focusing attention on cyclodextrins by taking advantage of their unique topologies such as their rigid cyclic structure, their ability to form inclusion complexes with molecules of appropriate size and shape, the presence of hydroxyl groups enabling coordination with metal ions.In this review, we discuss the most commonly used methods, which have been reported over the last forty years, for stabilizing catalytically active metal nanoparticles derived from various cyclodextrin-based systems. The most significant and representative examples devoted to the development of such systems are described, with the purpose of increasing stability, recyclability and catalytic activity, using supramolecular chemistry as a remarkable tool. Some pivotal aspects of their synthesis, characterization and catalytic behaviors are presented, with special attention to (i) the development of metal nanoparticles in solvent-dispersed form or immobilized onto supports in the presence of cyclodextrins or their derivatives, (ii) to the multifunctional role of cyclodextrins capable of acting as reducing agents, stabilizing/dispersing agents or mass transfer promoters, even possibly the three and (iii) to the design of more sophisticated catalytic systems, in which the cyclodextrin plays a central role of supramolecular host with dynamic equilibrium.

“…Generally, biodiesel contains less sulfur than fossil diesel; however, its composition depends on its raw feedstock and suppliers (Figure 4). For instance, the biodiesel derived from soybean oil (SO) contains several ppm of sulfur compounds, which is highly dependent on the crop conditions (e.g., soil properties and fertilizers) and region [85]. On the contrary, considering scum holds as a biodiesel feedstock, the sulfur content ranges from 600 to 1000 ppm [86].…”

The reforming of biofuels represents a promising technology for low carbon and renewable hydrogen production today. The core of the process is an active and stable catalyst, which can help to improve this technology and its efficiency. With this review, we aim to survey the more relevant literature on heterogeneous catalysts for the reforming of biofuels with improved sulfur tolerance. The review is structured into four main sections. Following the introduction, the fundamental aspects of sulfur poisoning are discussed. In the third section, the basic principles of the reforming of biofuels are reported, and finally, in the fourth section—the core of the review—recent progresses in the development of sulfur resistant catalysts are discussed, distinguishing the role of the metal (noble and non-noble) from that of the support.
