The chemical industry uses precious metals or metal oxides based catalysts. These catalysts are expensive and are not highly selective, increasing waste and producing greenhouse gases. In contrast, carbon based materials are environmentally acceptable and cheap combining efficient use of energy and resources. In heterogeneous materials, electrical, thermal and photophysical properties can be controlled and modulated providing a broad range of applications. We have demonstrated that organic dyes can be successfully used to construct a surface supported nanomaterials. Covalently modified surfaces with (photo)active units, become increasingly important as they offer stability, show more superior properties in contrast to supramolecular interactions or individual components. Interest lies in (photo)catalytic processes whereby highly reactive intermediates can be generated and used under mild conditions to construct novel metal-free hybrid catalysts for a given application. Different projects are available in this area in: Oxidation of alkanes as a feedstock of high-value-added chemicals. Oxidation of cheap alkanes to high-value-added chemicals is an important industrial challenge. Selectivity of oxidation using various industrially relevant catalytic systems, is poor due to inertness of the C-H bonds and the chemical process is problematic to control, leading to over-oxidation. The production of terephthalic acid and cyclohexanone from alkanes is achieved. It uses metal catalysts and a large quantity of acid to yield only moderate selectivity. Focus is on design and testing of recyclable graphene based catalysts to decrease the negative economic and environmental impact of these processes. Oxygen reduction metal-free electrocatalysts - Oxygen reduction is central to many industrially relevant applications such as energy storage and conversion devices. However, slow kinetics of the electrochemical oxygen reduction is a limitation, and requires a catalyst such as Pt. Current developments focus on replacement of platinum with cheaper and more efficient metals. Focus will be on development of metal free carbon-based alternatives and develop photocatalysts for metal-free type of C-C bond formation. The project aims to develop: 1) the metal free hybrid photocatalysts and 2) the analytical platform to assess their oxidation and reduction abilities. Our choice of photocatalysts’s design is directed by two objectives: (i) modification of graphene surface by planar, electron-rich molecules sensitive to photochemical ET with high extinction coefficient in visible region; (ii) methodology allowing efficient and solution-processable functionalisation for Metal-free catalysis for the degradation of organic pollutants. The project aims to develop an analytical platform for degradation of pollutants e.g. organic dyes in waste water using metal-free carbon based (photo)catalysts.

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.
The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
