Abstract

Global energy concerns motivate the development of new and improved technologies for solar energy capture, with semiconductor photocatalysis and photothermal catalysis expected to play key roles in meeting the energy needs of future societies. This talk will overview some of our recent research aimed at solar-driven catalyst development for H2 production in alcohol-water systems, the reduction of CO2 to CO and the conversion of N2 to NH3. Our research has identified 2D nanosheet photocatalysts made from earth-abundant elements, especially layered double hydroxides (M2+M3+-LDH, where M2+ = Ca2+, Mg2+, Mn2+, Fe2+, Co2+, Ni2+ or Zn2+ and M3+ = Al3+, Ga3+ or Fe3+) and graphitic carbon nitride (g-C3N4), as promising low cost candidates for the aforementioned processes under direct sunlight. Strong emphasis here will be placed on the importance high resolution transmission electron microscopy (HRTEM), synchrotron-based X-ray spectroscopies (XPS, EXAFS) and DFT calculations for the understanding of catalyst function and ultimately performance optimization via exploitation of structure-activity relationships.


Biography

Geoffrey Waterhouse(School of Chemical Sciences, The University of Auckland) is a Fellow of the New Zealand Institute of Chemistry and a Principal Investigator in the MacDiarmid Institute for Advanced Materials & Nanotechnology (a New Zealand Centre of Research Excellence). He is also a Chair Professor of the South China University of Technology, a Chair Professor of Shandong Agricultural University and a Guest Professor in the Key Laboratory of Photochemical Conversion and Optoelectronic Materials of the Chinese Academy of Sciences (CAS). In 2016 he was awarded the International Partnership Award for Young Scientists of the Chinese Academy of Sciences in recognition of outstanding fundamental collaborative work conducted with a CAS partner. His research expertise includes nanomaterials synthesis, optical sensor fabrication, catalysis and the development of novel drug delivery platforms. He has published 185 SCI journal articles (mean impact factor > 7), including high impact factor journal publications in Chemical Society ReviewsNature ChemistryNature CommunicationsAdvanced MaterialsAdvanced Energy MaterialsJACSAngewandte Chemie International EditionACS NanoJournal of Catalysis and other leading journals. His journal articles have been cited more than 7500 times, and he has an h-index of 46 (Source: Google Scholar). Geoffrey is one of New Zealands foremost users of synchrotron techniques, and holds or has held a number of elected positions that serve the Australasian synchrotron science community.
