About this collection
Introduced by Professor Stephen Skinner, Imperial College London
We are delighted to highlight the diversity of research activity within the UK materials chemistry community in the field of energy and sustainability. As well as demonstrating the diversity of topics investigated by UK researchers, this collection shows extensive collaborations between leading UK groups and international industry partners, and demonstrates the leading position of UK researchers internationally as evidenced by their collaborations with groups from China, Singapore, and the USA among others.
In this collection the work includes research on carbon based materials for photochemical conversion, carbon dioxide capture, oxygen storage materials, graphene for supercapacitors, new concepts for microbial fuel cells, cerium based fuel cells and nanomaterials for lithium and sodium battery based devices. In these papers the groups use innovative materials preparation techniques to improve manufacturing costs, apply in-situ characterization techniques to provide unique insights into device operations and consider degradation and durability. This is of critical importance in, for example, methyl ammonium lead iodide photovoltaic devices. It is exciting and encouraging to see the internationally leading activity that groups from the UK are involved with, and the pioneering work that our researchers are presenting.
