The photocatalytic degradation of two quinolone-type antibiotics (ciprofloxacin and levofloxacin) in aqueous solution was studied, using catalysts based on ZnO nanoparticles, which were synthesized by a thermal procedure. efficiency subsequently optimized incorporating different co-catalysts gC3N4, reduced graphene oxide, nanoparticles gold. fully characterized electron microscopy (TEM SEM), XP...

Peroxymonosulfate (PMS) activation has gained increasing attention for its water remediation. In this work, carbon nanotube-supported FeCo2O4 nanoparticles (FeCo2O4/CNT) were prepared and showed tremendous potential as a catalyst PMS activation. The synergistic effect between CNT in FeCo2O4/CNT promotes better catalytic performance than individual or FeCo2O4. synthesized could reach 100% phenol...

For the production of cyclic carbonates from cycloaddition CO2 with epoxides, halogen pollution and product purity are two most common problems due to usage homogeneous halogen-containing catalysts such as ammonium salt alkali metal halide. Hence, development a novel, halogen-free efficient catalyst for synthesis high-purity is significant. Here, series acid–base bifunctional Ce1-xZrxO2 nanorod...

Noble metal alloys are important in large-scale catalytic processes. Alloying facilitates fine-tuning of catalytic properties via synergistic interactions between metals. It also allows for dilution of scarce and expensive metals using comparatively earth-abundant metals. RhAg and RhAu are classically considered to be immiscible metals. We show here that stable RhM (M = Ag, Au) nanoparticles wi...

Metal nanoparticles and metal oxides promisingly provide different catalytic active sites at their interfaces. Constructing high-density interfaces is essential to maximize synergies. Herein, a Cu–Co3O4 interfacial structure produced via pyrolysis moderate oxidation from metal-organic frameworks has been designed boost the intrinsic activity. The composites exhibit turnover frequency of 57.5 mi...

A novel method for the preparation of Ni-Cu oxide catalysts—deposition on stainless steel meshes using hollow cathode plasma jet sputtering—was studied. This allows thin films. Consequently, whole volume active phase is readily accessible reactants and can be employed in catalytic reaction due to negligible effect internal diffusion. As a result, activity our sputtered catalyst was seven times ...

We employed an efficient and facile route to synthesise monodisperse Pd-based bimetallic nanocrystals (MPd: M = Cu, Co and Ni) via a controlled co-reduction of Pd(ii) chloride and M(ii) nitrate at 200-230 °C in the presence of oleylamine (OAm). These monodisperse Pd-based nanocrystals have small dimensions, unique structures and homogeneous morphology, thus exhibit efficient catalytic activitie...

Catalysis by gold supported on reducible oxides has been extensively studied, yet issues such as the nature of the catalytic site and the role of the reducible support remain fiercely debated topics. Here we present ab initio molecular dynamics simulations of an unprecedented dynamic single-atom catalytic mechanism for the oxidation of carbon monoxide by ceria-supported gold clusters. The repor...
