Catalysts with active, selective, and reusable features are desirable for sustainable development. The present investigation involved the synthesis characterization of bear-surfaced ultrasmall Pd particles (<1 nm) loaded onto surface magnetic nanoparticles (8–10 nm). amount loading magnetite is recorded as 2.8 wt %. process covered utilization scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission (TEM), inductively coupled plasma (ICP), X-ray photoelectron...
Finding environmentally acceptable and long-lasting catalysts that can convert carbon dioxide into compounds with additional value is of great interest.
Ammonia, which comprises 17.6 wt% hydrogen, demonstrates potential as a hydrogen storage medium. Catalysts made from cost-effective transition metals such cobalt (Co) and nickel (Ni), supported on Al₂O₃, are...
Abstract Design of solid‐supported metal catalysts (SSMCs) has made an increasingly important contribution to heterogeneous catalysis in terms fundamental understanding and technological applications. For instance, industrial use supported for oxidation, reduction, C−C bond formation reactions is highly prevalent. The reason behind this that such are economical, have high thermal stability, dispersion, exposed surface area, above all, reusability (up multiple subsequent cycles). Such...
Organic synthesis presents significant opportunities for converting the abundant and hazardous carbon dioxide (CO2) in atmosphere into a more sustainable source. To reduce footprint, we explored direct hydrogenation of CO2 to lower (C2‐4=) olefins using various catalysts composed ZrO2‐supported alkali‐metal‐promoted superparamagnetic iron oxide nanoparticles (SPIONs; Fe3O4). These are notable their straightforward preparation; employed cost‐effective dry‐mixing method create range alkali...
A catalytic system for selective transformation of furfural into biofuel is highly desirable. However, hydrogenation the C=O group over furan ring to produce ether in one step challenging. Here, we report preparation a series magnetically recoverable FeCo@GC nano-alloys (37-40 nm). Fe3 O4 (3-5 nm) and MOF-71 (Co), used as Co C source, were mixed together range Fe/Co ratios, then encapsulated graphitic carbon (GC) shell prepare such alloys. STEM-HAADF shows darker core made FeCo carbon....
Chemical modification of chitosan was successfully carried out using three derivatives namely: 3 hydroxybenzaldehyde, 2,3-dihydroxybenzaldehyde, and 3,5-di-tert-butyl-2-hydroxybenzaldehyde by a condensation reaction. Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area, thermal gravimetric analysis (TGA), X-ray diffraction (XRD) methods were performed for characterization the chitosan-derived Schiff base adsorbent...
The development of sustainable and cost-effective catalysts with higher activity selectivity is desirable due to economic environmental concerns. Here, the fabrication iridium (Ir) on superparamagnetic iron oxide nanoparticles (SPIONs) (Ir@Fe3O4) hydrogenation various N-heteroaromatic styrenes compounds under molecular hydrogen pressure have been disclosed. composite material confirmed by XRD, Raman, SEM, TEM, XPS analysis.

Abstract In this study, iridium nanoparticles (IrNPs) on superparamagnetic iron oxide (SPIONs) are used to catalyze N‐heteroarene and styrene hydrogenation processes. The IrNP@SPIONs catalyst was fabricated by reducing the Ir‐salt precursors in deionized water SPIONs (Fe 3 O 4 ), its catalytic reactivity for of N‐heteroarenes under mild reaction conditions as hydrogen pressure evaluated. characterized FTIR, Raman, XRD, SEM, XPS, ICP‐OES, TEM. results showed that IrNPs@SPIONs exhibited >99...
