Abstract The development of an efficient electrocatalyst for HMF oxidation to FDCA has been in the early stages. Herein, NiNPs/GO‐Ni‐foam is fabricated as production. However, electrocatalytic performance untreated observed with moderate Faradaic efficiency (FE) (73.0%) and yield (80.2%). By electrochemically treating alkaline solution positive potential at different treatment durations, degree NiOOH on metal surfaces changed. distinctive activity obtained when using degrees allows...
The enantioselective synthesis of chiral compounds is crucial importance for a wide range potential applications, especially in cosmetic and pharmaceutical industries. Recently, imprinted mesoporous platinum films, produced by the electrodeposition metal, simultaneous presence lyotropic liquid crystalline phase nonionic surfactants as mesoporogens templates, have been applied electrocatalysts selective stationary phases asymmetric separation compounds, respectively. However, an expensive...
The sustainable conversion of biomass-derived compounds into high added-value products is a very important contemporary scientific challenge. In this context, we report here the simultaneous electro-oxidation/-reduction compound in one-pot approach using bipolar electrochemistry. Bifunctional Pt/Au Janus electrocatalysts are employed for selective furfural both, furfuryl alcohol and furoic acid, which can't be achieved when non-Janus particles. results emphasize benefits electrochemistry...
As the catalytic performances typically depend on various factors, especially distribution of Al species in zeolite framework, this contribution, hierarchical nanospherical ZSM-5 zeolites have been successfully synthesized using uniform aluminosilicate (AS) nanobeads containing silica and alumina as a starting material to improve dispersion framework. The were characterized by means XRD, TEM, SEM, EDS, N2 physisorption, 27Al MAS NMR, NH3-TPD. This example demonstrates that use AS can...
The chemical state and acidity of ceria incorporated in hierarchical zeolites have been successfully tuned due to the presence structures zeolite nanosheets interaction between supports with different Si/Al ratios. Ce reactivity designed materials for ethanol dehydration is remarkably improved improvement metal-support interaction, acidity, reducibility species, eventually facilitating an unprecedented yield ethylene close 100%. This finding opens up a new perspective development based...
The nanostructured free-standing NiAl-MOR-CNTs electrocatalysts containing carbon nanotubes (CNTs) deposited on mordenite (MOR) zeolite/NiAl-layered double hydroxide (NiAl-LDH) have been successfully fabricated. Initially, the core-shell NiAl-LDH-MOR with hierarchical structures was observed via an aqueous miscible organic solvent treatment process to deposit nanosized NiAl-LDH homogeneously a zeolite surface. synthesized composites were calcined produce highly dispersed metal oxides...
The highly selective oxidation of alcohols to aldehydes has been achieved due the synergic effect Pt and CeO2 supported on hierarchical zeolites. combination strongly enhances catalytic performance benzyl alcohol benzaldehyde with respect isolated materials. In addition, zeolite not only increases fraction exposed active sites because its high surface area that can prevent aggregation nanoparticles, but also affects state cerium. presence a content trivalent Ce species (Ce3+) benefits...
The rational design of ultra-small metal clusters dispersed on a solid is crucial importance in modern nanotechnology and catalysis. In this contribution, the concept catalyst fabrication with very size platinum nanoparticles supported hierarchical zeolite surface via one-pot hydrothermal system was demonstrated. Combining gel ethylenediaminetetraacetic acid (EDTA) as ligand precursor during crystallization process, it allows significant improvement dispersion support. To illustrate...
