Ammonia borane hydrolysis is considered as a potential means of safe and fast method H2 production if it efficiently catalyzed. Here series nearly monodispersed alloyed bimetallic nanoparticle catalysts are introduced, optimized among transition metals, found to be extremely efficient highly selective with sharp positive synergy between 2/3 Ni 1/3 Pt embedded inside zeolitic imidazolate framework (ZIF-8) support. These much more for release than either or analogues alone on this support,...
Non-noble metal nanoparticles are notoriously difficult to prepare and stabilize with appropriate dispersion, which in turn severely limits their catalytic functions. Here, using zeolitic imidazolate framework (ZIF-8) as MOF template, catalytically remarkably efficient ligand-free first-row late transition-metal prepared compared. Upon scrutiny of the principles hydrolysis ammonia-borane, highest total turnover frequency among these transition metals is achieved for templated Ni 85.7 molH2...
Abstract A ligand design is proposed for transition metal nanoparticle (TMNP) catalysts in aqueous solution. Thus, a tris(triazolyl)‐polyethylene glycol (tris‐trz‐PEG) amphiphilic ligand, 2 , used the synthesis of very small TMNPs with Fe, Co, Ni, Cu, Ru, Pd, Ag, Pt, and Au. These TMNP‐ were evaluated compared model 4‐nitrophenol reduction, proved to be extremely efficient. High catalytic efficiencies involving use only few ppm PdNPs, RuNPs, CuNPs also exemplified Suzuki–Miyaura, transfer...
Abstract Sodium borohydride hydrolysis catalyzed by composite nanomaterials has long been proposed as a viable possibility for hydrogen generation, but it required either expensive noble metals or sophisticated composites. Herein, the catalysis of NaBH 4 is studied with single earth‐abundant Fe, Co, Ni, and Cu nanoparticles supported metal organic framework (MOF), ZIF‐8. It appears that CoNPs@ZIF‐8 most efficient selective catalyst in this series. The turnover frequency (TOF) related to...
Electrochemical oxidation of biomass substrates to valuable bio-chemicals is highly attractive. However, the design efficient, selective, stable, and inexpensive electrocatalysts remains challenging. Here it reported how a 3D ordered mesoporous Co
Cobalt is an alternative catalyst for furfural hydrogenation but suffers from the strong binding of H and furan ring on surface, resulting in low catalytic activity chemoselectivity. Herein, by constructing a Pd–Co interface cobalt oxide-supported Pd catalysts to tailor d-band center Co, concerted effort Co boosts performance hydroconversion cyclopentanone cyclopentanol. The increased dispersion acid etching Co3O4 promotes reduction Co3+ Co0 enhancing hydrogen spillover, favoring creation...
The copper(I)-catalyzed azide alkyne cycloaddition (CuAAC) using the conventional Sharpless–Fokin catalyst that consists of CuSO4 + Na ascorbate, most well-known and used "click" reaction, is considerably accelerated by addition a tris(triazolyl)-poly(ethylene glycol) (tris-trz-PEG) amphiphilic ligand in water under ambient conditions. Only parts per million amount CuI were necessary to reach quantitative yields with TONs up 86000 TOFs 3600 h–1. was fully recycled, reused at least six times...
α-Fe<sub>2</sub>O<sub>3</sub> nanoclusters supported onto a graphene oxide catalyst are shown for the first time to catalyze Suzuki–Miyaura coupling and 4-nitrophenol reduction in aqueous solution with only parts-per-million loading.
2,5-Furandicarboxylic acid (FDCA) is a promising biomass-derived alternative to fossil-based terephthalic acid. The catalytic oxidation of 5-hydroxymethylfurfural (HMF) FDCA widely recognized as viable route for producing at industrially relevant concentrations (approximately 20 wt %); however, this has not yet been achieved. Toward goal, we report that through controlled engineering an oxygen-vacancy-enriched Mn/Co oxide the support Pt nanoparticles, heterostructure Pt/PtO2 with...
Mono-, bis-, and tris-1,2,3-triazole ligands are used for the stabilization of gold nanoparticles (AuNPs), catalytic activities these AuNPs in 4-nitrophenol reduction by NaBH4 water compared as well with polyethylene glycol 2000 (PEG)- polyvinylpyrrolidone (PVP)-stabilized AuNPs. The excellent results specifically obtained tris-triazolate ligand terminated a PEG tail taken into account synergy between weakness tris-triazole-AuNP bond combined stabilizing bulk.
The catalytic activity of Cu(0) NPs is boosted upon aerobic oxidation, forming Cu<sub>2</sub>O NPs, and further improved on an SBA-15 support.
Peanuts are prone to insect damage, breakage, germination, mildew, and other defects, which makes the quality of peanuts uneven. The difference in peanut pod price economic benefit also have a big difference. classification pods according is an important part improving product grade market competitiveness. Real-time, accurate, non-destructive detection can effectively improve utilization commercial value peanuts. strong subjectivity manual low efficiency accuracy mechanical caused...

The modes of generation nanoparticles (NPs) are great interest for multiple applications in catalysis, optics, sensing, and nanomedicine. Here, fast reduction CuSO4·5H2O Ag salts by commercial cobaltocene yields small, stable, water-soluble Cu NPs with a narrow size distribution without any other ligand or support. variation the salt counteranion (NO3–, F–, BF4–) strongly influences both plasmonic absorption AgNPs synthesized this way high apparent rate constant AgNP-catalyzed 4-nitrophenol...
