CeO2-based catalysts with engineered morphologies for soot oxidation to enhance soot-catalyst contact
AS MORPHOLOGY PLAYS A RELEVANT ROLE IN SOLID/SOLID CATALYSIS, WHERE THE NUMBER OF CONTACT POINTS IS A CRITICAL FEATURE IN THIS KIND OF REACTION, THREE DIFFERENT CERIA MORPHOLOGIES HAVE BEEN INVESTIGATED IN THIS WORK AS SOOT OXIDATION CATALYSTS: ceria nanofibers, which can become organized as a catalytic network inside diesel particulate filter channels and thus trap soot particles at several co...
متن کاملEffects of Nano-CeO2 with Different Nanocrystal Morphologies on Cytotoxicity in HepG2 Cells
Cerium oxide nanoparticles (nano-CeO₂) have been reported to cause damage and apoptosis in human primary hepatocytes. Here, we compared the toxicity of three types of nano-CeO₂ with different nanocrystal morphologies (cube-, octahedron-, and rod-like crystals) in human hepatocellular carcinoma cells (HepG2). The cells were treated with the nano-CeO₂ at various concentrations (6.25, 12.5, 25, 50...

متن کاملReaction Mechanism in Catalytic Soot Combustion with CeO2 Catalysts
Introduction Diesel soot elimination is a very difficult problem. The catalytic filters seems to be one of the technological alternatives in order to trap and burn the soot, at the exhaust gas temperature. In order to advance in a rational catalyst design, the reaction mechanism must be understood. In spite of this need, and even though there are many papers in the field, detailed studies regar...
متن کاملAu/CeO2 Catalysts: Structure and CO Oxidation Activity
In this comprehensive review, the main aspects of using Au/CeO2 catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria support (presence of doping cations, oxygen vacancies concentration, surface area, redox properties, etc.) in the dispersion and chemical state of gold are revised. The prop...
