Journal: :Catalysts 2022

Here, we report a visible light-induced-trimetallic catalyst (Cu0.5Zn0.5Fe2O4) prepared through green synthesis using Tilia plant extract. These nanomaterials were characterized for structural and morphological studies powder x-ray diffraction (P-XRD), scanning electron microscopy (SEM) thermogravimetric analysis (TGA). The spinel crystalline material was ~34 nm. In benign reaction conditions, ...

Direct ethanol fuel cells (DEFCs) are considered one of the most promising energy resources for portable power devices. The current mainstream catalysts used DEFCs Pt- or Pd-based, which facilitate partial oxidation to CH3CHO CH3COOH, but not C—C bond cleavage, is inevitable path complete ethanol. In addition, noble easily poisoned by CO, shortening their lifespan and stability, thus inhibiting...

Abstract Fenton processes allow to degrade and mineralize toxic organic contaminants, yet classical require continuously adding hydrogen peroxide ferrous ions, costly solution pH adjustment, treatment of secondary iron sludge pollution. Heterogeneous electro-Fenton deliver oxidizing radicals with only oxygen electricity consumed. Bifunctional catalysts the synthesis activation simultaneously, e...

The therapeutic effect of chemodynamic therapy (CDT) is significantly restricted by the stern reaction conditions and slow rate Fenton (pH 3-4). Herein, we report an ultrasmall trimetallic (Pd, Cu, Fe) alloy nanozyme (PCF-a NEs) possessing dynamic active-site synergism, thus exhibiting a cascade glutathione peroxidase (POD) mimicking activities in circumneutral pH. PCF-a NEs exhibit phototherma...

A high-throughput pulsed laser ablation (HT-PLA) system was developed to rapidly prepare uniformly sized singleand multi-metallic nanoparticles with different diameters for catalytic applications. Catalytic materials containing Rh, bimetallic Rh/Pt and trimetallic Rh/Pt/Au nanoparticles were synthesized from targets prepared by blending, tableting and sintering powders of pure metals, and by di...
