Ceria (CeO2) nanorods with well-defined surface planes can be synthesized and utilized for the hydrogenation of nitroaromatics. The CeO2 nanorods containing a {110} plane can efficiently and selectively catalyse the hydrogenation of nitroaromatics with N2H4 as a reducing agent, while nano-ceria with a {100} or {111} plane shows poor performance for the reaction.

Understanding the origin of enhanced catalytic activity is critical to heterogeneous catalyst design. This is especially important for non-noble metal-based catalysts, notably metal oxides, which have recently emerged as viable alternatives for numerous thermal catalytic processes. For thermal catalytic reduction/hydrogenation using metal oxide nanoparticles, enhanced catalytic performance is typically attributed to increased surface area and oxygen vacancies.

Efficient catalytic systems for various organic transformations in green solvents, especially water, are in great demand. Catalytically active bis-NHC complexes of palladium(II) based on imidazole-4,5-dicarboxylic acid with different lipophilicities were obtained. The synthesis of imidazolium salts was complicated by the formation of side products of nucleophilic substitution by iodide ions in the Menshutkin reaction involving alkyl iodides, which was successfully resolved by using alkyl tosylates.

The circular economy and the depletion of Earth's resources highlight the need to transform waste into value-added emerging materials like carbon quantum dots (CQDs), which show great promise in energy storage, catalysis, and other applications. The production of catalytically active CQDs from biomass garners significant attention due to their unique advantages, such as ease of availability, natural abundance, renewability, low cost, and environmental friendliness. This review addresses the synthesis of CQDs from biomass, the factors influencing their properties and performance, and their diverse applications in catalytic hydrogenation reactions, selective reduction of nitroaromatic compounds, and azo dyes.

Metal hydrides are sensitive to HO and O, which reduces the atom efficiency of the hydride donors. Silver (Ag) is an inexpensive coinage metal; however, its lower activity compared to gold, platinum, and palladium limits its application in catalytic hydrogenation. Here, electron-deficient metallic single-atom Ag (AgSA) was loaded onto γ-AlO using a benzoquinone- and KNO- assisted photolysis approach.

This study developed a novel and highly active heterogeneous catalyst of nickel nanoparticles supported on β-cyclodextrin-grafted magnetic FeO nanoparticles (Ni@β-CD@FeO). β-CD, a biodegradable, biocompatible, green, and non-toxic cyclic oligosaccharide, was modified with FeO nanoparticles to create β-CD@FeO. The nickel was then immobilized onto this support.
