Chapter 1Introduction

Kapil, Nidhi

Pages: 1 –44

[Propylene oxide (PO; chemical formula C3H6O; IUPAC nomenclature: 2-methyloxirane molar mass 58.08 gmol−1, Fig. 1.1) is a colourless, low boiling liquid with a pleasant, ethereal odour [1]. It is an important building-block chemical that is used to produce numerous commercial materials [2, 3]. As...

Chapter 2Propylene Epoxidation Reactor Design

Kapil, Nidhi

Pages: 45 –58

[Designing and building a reactor set-up can be a challenging task. This chapter will discuss the detailed steps of building a reactor set-up from scratch. This reactor set-up will be used for direct gas phase epoxidation of propylene using hydrogen and oxygen in the presence of inert gas. The...

Chapter 4Supported Gold Clusters as a Stable Catalyst for Propylene Epoxidation

Kapil, Nidhi

Pages: 87 –111

[Designing a stable and selective catalyst with high H2 utilisation is of pivotal importance for the direct gas phase epoxidation of propylene. This work describes a facile one-pot methodology to synthesise ligand-stabilised sub-nanometre gold clusters immobilised onto a zeolitic support (TS-1)...

Chapter 5Tailoring Gold Nanoparticles with Tunable Core Size and Their Catalytic Applications

Kapil, Nidhi

Pages: 113 –129

[The electronic and geometric properties at and around the active site of catalysts can be tuned by using organic moieties during synthesis. Here, we discuss a facile approach to synthesise gold nanoparticles using various Au(I) precursors and study the effect of steric hindrance of these ligands...

Chapter 6Propylene Epoxidation on Au/Ti-Containing Supports: The Effect of the Support

Kapil, Nidhi

Pages: 131 –155

[The supports can have a substantial influence on the catalytic properties of metal supported catalysts. Herein we demonstrate the immobilisation of pre-synthesised Au clusters on different Ti-containing supports with various physical properties. This immobilisation technique is highly versatile...

Chapter 7Controlled Engineering of Supported Metal Nanoparticles Using Electrospraying: Robust Removal of Stabilising Ligands

Kapil, Nidhi

Pages: 157 –181

[A facile method for the synthesis of single and bimetallic metal nanoparticles with narrow size distribution is utilised. It is based on the electrospraying of a metal precursor solution into a surfactant solution, which acts as a reducing and stabilising agent. This synthesis method is...

Chapter 8Conclusions and Future Work

Kapil, Nidhi

Pages: 183 –191

[The main objective of this thesis was to design a stable and active catalyst for the direct gas phase epoxidation of propylene.]
