Heterogeneous bimetallic catalysts are widely used in industrial processes, and the structural features of have profound impacts on their properties numerous catalytic processes. Bimetallic nanoclusters with particle sizes ≤1 nm shown better performances various reactions comparison to conventional nanoparticles above 1 nm. Despite progress made recent years synthesis studies nanoclusters, achieving a fundamental understanding structure–reactivity relationships at molecular atomic levels...
Abstract Non‐noble bimetallic alloys serve as an alternative catalytic material for noble metal‐based catalysts that could be applied in selective hydrogenation of unsaturated compounds. However, maintaining the stability nanoparticles process remains a substantial challenge, due to its high tendency structural transformation upon reactive circumstances. Herein, this problem is solved by constructing carbon‐protected sites within carbon layer‐coated Ni−Fe nanoalloy composite via pyrolysis...
Abstract Non‐noble Ni−Cu alloys serve as an alternative catalytic material for noble metal‐based catalysts that could be applied in the efficient conversion of levulinic acid (LA) into high value γ‐valerolactone (GVL). However, maintaining stability nanoparticles LA hydrogenation process remains a substantial challenge, Herein, this problem is solved by constructing carbon‐protected sites within carbon layer‐coated nanoalloy composite via pyrolysis NiCu x (OH)/glucose precursor. The...
The significance of the nonoxidative dehydrogenation middle-chain alkanes into corresponding alkenes is increasing in context world's declining demands on transportation fuels and growing demand for chemicals materials. derived from reaction can be transformed value-added downstream processes. Due to presence multiple potential sites, mechanism more complicated than that light alkanes, there are few prior studies elucidating their detailed structure-reactivity relationship. In this work, we...
We report a general route to decipher the apportionment of metal ions in bulk metal-organic frameworks (MOFs) by solid-state nuclear magnetic resonance spectroscopy. demonstrate this Mg1-xNix-MOF-74, where we uncover all eight possible atomic-scale Mg/Ni arrangements through identification and quantification distinct chemical environments 13C-labeled carboxylates as function Ni content. Here, use susceptibility, bond pathway, density functional theory calculations identify local bonding...
Abstract Efficient synthesis of higher alcohols from syngas over a single‐metal catalyst remains challenging because both active sites for CO dissociation and molecular adsorption are required. We report herein that iron nitrides can directly catalyze to with high selectivity. Three nitride catalysts (Fe 2 N, Fe 3 4 N) were fabricated via the nitriding α‐Fe their structures confirmed by X‐ray diffraction (XRD) Mössbauer spectroscopy (MES). Moreover, no carbides detected even after conversion...
The intrinsic principle of the electronic property Pt catalysts for selective hydrogenation 1,3-butadiene was systemically elucidated.
Experimentally observed magnetic properties are usually statistically averaged from bulk materials and information associated with the local chemical environment cannot be specified. Against this backdrop, we propose a theoretical strategy to provide an in-depth understanding of multi-role for metrics that may contribute apparent moment iron borides. In particular, demonstrate through systematic manipulation iron/boron stoichiometry six prototype borides tune their structural electronic...
The intrinsic activity of the Re-catalyzed cross-metathesis ethene and 2-butene was highly boosted by promotion boron.
Abstract Catalytic olefin metathesis represents a vital reaction in the chemical industry, as it provides feasible route for interconversion of olefins. However, traditional supported catalysts usually suffer from low activity due to sluggish kinetics formation catalytically active metal‐carbene species. This work tackles this issue by taking phosphoric acid promoter and constructing Brønsted acidic site cooperate with MoO x sites, thus facilitating Mo‐carbene. It turns out that turnover...
Elucidation of the intrinsic working principle electronic property Pt catalysts within selective hydrogenation 1,3-butadiene in presence CO remains a substantial challenge. We solve this problem through synthesis series bimetallic Pt-Sn clusters encapsulated zeolite channel and followed by manipulation composition to further tuning Pt. By excluding possible interference from cluster size distribution, we were able evaluate solely influence on catalytic performance. In CO, volcano correlation...
