Abstract :

Clean energy technologies are critically important to mitigate climate change and sustain societal development. Advanced materials hold the key to enhancing the efficiency and lowering the cost of such technologies. From the understanding of molecular or charge interactions with materials, the talk will address the issues of effective sorbents for CO2 capture and for hydrogen purification and storage. Large-scale energy storage is necessary to increase the efficiency and the responsiveness of a future smart electricity grid incorporating renewables. Storing and supplying energy carriers (electrons and protons) at practical conditions pose great scientific and engineering challenges. Both experimental and theoretical approaches were applied to selected materials of high promise, e.g., doped/defective carbon, doped hydrides, metal/amine complexes and stable electrode materials. Finally, the talk will examine possible routes to speed up the development of clean energy technologies through multiscale materials engineering.

Biography :

Dr. Zheng-Xiao GUO was trained in Materials and Mechanical Engineering at Northeastern University/China, obtained his PhD from the University of Manchester/UK, with postdoctoral research experiences at the universities of Strathclyde and Oxford, before joining academic faculty at Queen Mary, University of London. He is currently a professor of Materials Chemistry at UCL, and has led research projects around £10m, involving consortia grants over £40m in the past 15 years, worked on critical issues from large engineering structures to atomic/molecular interactions in collaboration with policy makers, engineers, technologists and basic scientists. He leads an active team of 14 researchers pursuing integrated synthesis/simulation /characterisation of nanostructures/devices with molecular interactions for chemical sensing, gas separation, hydrogen storage/purification, and CO2 capture. He is currently institutional PI for 6 consortium projects, and a core member of the UK Hydrogen Energy Consortium (UKSHEC) since its inception, authored over 170 journal publications and 250 conference papers/presentations (with an H Index of 28), awarded the Beilby Medal 2000, jointly by the SCI, the RSC, and the IoM3 for “working theory for industry”. He is a UK representative of the Tasks 19, 22 and now 33 of the International Energy Agency on hydrogen storage, and a member of an EU Hytrain project on hydrogen storage, the UK leader for an EU EERA consortium on energy materials and process, coordinated by the UKERC, contributed to two MAT-UK’s energy strategic documents in 2007, launched by then DTI. In a wide context, he contributes to UCL’s overall international strategy and particularly overseas collaborations with the China region, and was the Focal-Point for UK-China collaborations in Nanotechnology & Materials Science (2009-2012), appointed by the UK Science and Innovation Network of the BIS, organised various collaborative events and high-level discussions among top academic institutions, policy makers and R&D centres to enhance international collaborations.
