Recent Advances in Tetra- (Ti, Sn, Zr, Hf) and Pentavalent (Nb, V, Ta) Metal-Substituted Molecular Sieve Catalysis

Metal substitution of molecular sieve systems is a major driving force in developing novel catalytic processes to meet current demands of green chemistry concepts and to achieve sustainability in the chemical industry and in other aspects of our everyday life. The advantages of metal-substituted molecular sieves include high surface areas, molecular sieving effects, confinement effects, and active site and morphology variability and stability. The present review aims to comprehensively and critically assess recent advances in the area of tetra- (Ti, Sn, Zr, Hf) and pentavalent (V, Nb, Ta) metal-substituted molecular sieves, which are mainly characterized for their Lewis acidic active sites. Metal oxide molecular sieve materials with properties similar to those of zeolites and siliceous molecular sieve systems are also discussed, in addition to relevant studies on metal–organic frameworks (MOFs) and some composite MOF systems. In particular, this review focuses on (i) synthesis aspects determining active site accessibility and local environment; (ii) advances in active site characterization and, importantly, quantification; (iii) selective redox and isomerization reaction applications; and (iv) photoelectrocatalytic applications.

“…Amines have important roles in many aspects of the modern industry, including the production of dyes, polymers, pharmaceutical/agrochemical reagents, and other value-added chemicals. − Many conventional strategies for the synthesis of organic amines have been well-established for Hofmann alkylation, nucleophilic addition, hydrogenation of nitriles and nitroarenes, , hydroamination, and others. However, these established methods are often limited by poor selectivity, require the use of environmentally damaging chemicals, produce highly toxic byproducts, and typically employ harsh reaction conditions. − With stricter environmental legislation continually being imposed, the development of novel sustainable strategies for the economic production of amines must be considered.…”

Uncovering Structure–Activity Relationships in Pt/CeO₂ Catalysts for Hydrogen-Borrowing Amination

et al. 2023

The hydrogen-borrowing amination of alcohols is a promising route to produce amines. In this study, experimental parameters involved in the preparation of Pt/CeO2 catalysts were varied to assess how physicochemical properties influence their performance in such reactions. An amination reaction between cyclopentanol and cyclopentylamine was used as the model reaction for this study. The Pt precursor used in the catalyst synthesis and the properties of the CeO2 support were both found to strongly influence catalytic performance. Aberration corrected scanning transmission electron microscopy revealed that the most active catalyst comprised linearly structured Pt species. The formation of these features, a function result of epitaxial Pt deposition along the CeO2 [100] plane, appeared to be dependent on the properties of the CeO2 support and the Pt precursor used. Density functional theory calculations subsequently confirmed that these sites were more effective for cyclopentanol dehydrogenationconsidered to be the rate-determining step of the processthan Pt clusters and nanoparticles. This study provides insights into the desirable catalytic properties required for hydrogen-borrowing amination but has relevance to other related fields. We consider that this study will provide a foundation for further study in this atom-efficient area of chemistry.

“…Developing a new catalyst with high activity and selectivity to primary amines remains a challenging task. The most extensively used catalysts are homogeneous Ru and Ir complexes, [2b,3] but they suffer from complex separation processes. Although several heterogeneous amination catalysts have been developed, such as supported Ru on HBEA, [4] TiO 2 , [5] and unsupported Ru NPs, [6] they still need a high loading of noble metal, which is increasingly expensive.…”

Boosting Amination of 1‐Octanol to 1‐Octylamine via Metal‐Metal Oxide Interactions in Ni_xFe₁/Al₂O₃ Catalysts

The synthesis of 1-octylamine, a primary platform molecule, remained a great challenge in catalysis. In this work, Ni x Fe 1 / Al 2 O 3 was used for direct amination of 1-octanol to 1-octylamine. Catalyst evaluation indicated that the promotion effect of Fe/Ni ratio on the catalytic amination activity followed a volcano curve while the selectivity to 1-octylamine was positively correlated with the Fe loading. Compared with the Ni/Al 2 O 3 catalyst, the amination activity was increased by 2.8 times by optimizing the Fe/Ni ratio to 0.33, and the selectivity to 1-octylamine was increased from 84.0 % to 96.3 % when increasing the Fe/Ni ratio from 0 to 1. Based on catalyst characterizations, the good performance of Ni x Fe 1 /Al 2 O 3 was ascribed to the combined modification effect of the NiFe alloy and NiÀ FeO x interface. The FeO x species enriched on the Ni particle surface provided sufficient Fe 2 + /Fe 3 + À O 2À sites for the activation of 1-octanol, and the cooperation between Ni sites and Lewis acid-base pairs enhanced the amination of 1-octanol to 1-octylamine. This work sheds new light on the design of Nibased catalysts without using a noble metal for primary amine preparation.
