Calcium fluoride offers a safe, readily available alternative to hydrogen fluoride in the production of fluoride-containing molecules and materials, but is plagued by poor solubility and low reactivity. We will address these problems by synthesizing soluble molecular systems containing Ca-F bonds, and exploit the nucleophilicity of these species in the construction (in particular) of B-F and Si-F bonds. A key facet of this project will be the development of multidentate ligands to prevent aggregation of the Ca-F unit and/or ligand exchange.

Bimetallic catalysts, featuring metal centres with complementary electronic capabilities, are known from enzymatic and heterogeneous systems to possess reactivity capabilities distinct from either metal in isolation. Molecular systems featuring an electron-rich transition metal and a Lewis acidic aluminium centre show great promise in small molecule activation, but catalyst development is hindered by a dearth of synthetic routes. By exploiting recently developed nucleophilic aluminium reagents we will generate a range of open-shell 3d metal M-Al bimetallics that can be systematically tuned to optimize reactivity characteristics - in particular with respect to C-H bond activation.

Hexagonal boron nitride (h-BN) is an isoelectronic analogue of graphitic carbon offering many of the advantages of graphite while also being electrically insulating and highly resistant to thermal shock. While graphite is an industrially versatile material, widely used in aerospace and automotive applications, methodologies for the fabrication of h-BN counterparts are not well established. This project will investigate new and sustainable routes for creating ceramic h-BN fibres: it will integrate the chemical design/synthesis of novel molecular B/N-containing precursors (Aldridge group) and BN polymers (Weller group), and the application of a blow-spinning methodology (Grobert group) to produce novel three-dimensional h-BN fibre assemblies in an efficient, inexpensive and environmentally friendly manner.

Routes to selective oxidation of glycerol and other polyols are difficult to realise using conventional catalysts.

The study of catalyst surfaces under real or close to real reaction conditions is vital for the understanding and design of new catalysts. Material properties such as oxidation states and the Fermi level/work function are highly sensitive to the environment and can vary significantly when measured under ultra-high vacuum conditions. With the recent development of monolayer graphene membranes, atmospheric pressure X-ray photoelectron spectroscopy (AtmPXPS) can access material properties during reactions and even monitor the reaction products. In this project, the student will manufacture novel particulate and thin film photocatalysts using atomic layer deposition (ALD) directly coupled to the AtmPXPS setup which will allow the study of their nucleation and growth mechanism before focusing on the evolution of their surface properties under photocatalytic reaction conditions. This will shed light on the catalytically active sites during industrially relevant reactions such as the hydrogenation of CO₂ or the splitting of water into green hydrogen.

Delivering upon net-zero carbon targets requires more and better batteries. Solid state batteries are a key target for the field as they could obviate problems of liquid electrolyte leakage, short-circuit and may improve safety. Their successful delivery depends upon discovery of high conductivity, stability and electrode compatible solid electrolytes. We will develop block polymer electrolytes and binders, specifically materials incorporating hetero-atoms S and O to increase compatibility and surface adhesion to inorganic materials. By applying efficient catalysis, we will prepare precision polymers addressing both battery electrochemical and mechanical performance issues. These polymers are designed to adhere, structure and control interfaces with various inorganic materials, including the electrodes and solid-state inorganic sulphide electrolytes. The optimized inorganic-polymer composites will be fully tested and outcomes will feedback into materials design.
