Abstract

Aluminas supported noble metal nanoparticles have been synthesized by a new ionothermal process. The method used is easy to implement and allows obtaining catalysts in one step with high specific surface area. In addition, the metallic phase in the composites is highly dispersed and exhibits homogeneous size.

Highlights

Since the discovery of the M41S family by Mobil, the interest in mesostructured materials becomes more and more important due to the possibility of controlling the pore structure of solids [1,2]
Aluminas supported noble metal nanoparticles have been synthesized by a new ionothermal process
Among all the materials studied, the synthesis of Al2O3 with high specific surface area still represents a major challenge for chemical industries because of its extensive use as adsorbents and catalysts supports for numerous applications such as catalytic cracking, hydrocarbons reforming, environmental reactions, etc

Summary

Introduction

Since the discovery of the M41S family by Mobil, the interest in mesostructured materials becomes more and more important due to the possibility of controlling the pore structure of solids [1,2]. Aluminas supported noble metal nanoparticles have been synthesized by a new ionothermal process. We report a method allowing the direct (one-pot synthesis) functionalization of aluminas by noble metals using the Evaporation Induced Self Assembly (EISA) process.
