Chapter 1Introduction

Esposito, Serena

Pages: 1 –12

[Chemistry of materials gathers a wide range of chemical routes that allow producing materials for different processes. Researchers working on chemical synthesis constantly explore new material formulations with tailored properties and functionalities to run chemical processes at relatively low...

Chapter 2“Traditional” Sol–Gel: The Chemistry of Alkoxides

Esposito, Serena

Pages: 13 –20

[Nowadays, sol–gel chemistry collects plenty of fascinating strategies to prepare materials from solution state precursors, however it originated with the hydrolysis and condensation of metal alkoxides. The first metal alkoxide was prepared from silicon tetrachloride (SiCl4) and alcohol by...

Chapter 3From (Sub)colloidal Growth to the Gel Structure

Esposito, Serena

Pages: 21 –31

[An important consideration in the study of the sol–gel method is that there is no universal recipe for the preparation of a selected catalytic formulation. This means that it is not possible to provide a scheme for the preparation of a catalyst using the sol–gel process, as the synthesis route...

Chapter 4From Wet Gel to the Final Product: Draw Your Way

Esposito, Serena

Pages: 33 –41

[Once the gel is obtained, the water and alcohol that fill the porosity of the solid network must be removed through drying treatments to readily convert the wet gel in a dry solid. The methods of liquid extraction, as well as the other steps in the sol–gel process, can play an important role in...

Chapter 5Evolution of Sol–Gel Chemistry

Esposito, Serena

Pages: 43 –51

[Since the early studies on hydrolysis and condensation reactions of silicon alkoxides, progress in the knowledge of sol–gel chemistry and its potential has never stopped. The possibility of varying both parameters and precursors is boundless, resulting in ever more finely tailor-made materials....

Chapter 6Synthetic Strategies for (Supported) Metal and Metal Oxide Catalysts: Case Studies

Esposito, Serena

Pages: 53 –71

[As outlined in previous chapters, the sol–gel method, which originated around the preparation of silica, has developed massively over time, generating a plethora of different methodologies and chemistries. This inexhaustible source of synthetic pathways has been a powerful tool at the research...
