SUMMARY:School of Chemistry Colloquium:  Professor Dermot O'Hare (Oxford University)- RSC Prize Lecture
DESCRIPTION:Layered double hydroxides (LDHs) are a highly tunable class of inorganic materials with the general formula [M(1--x)M'x(OH)2]a+ [A¬--a/n] where M and M' are most commonly divalent and trivalent metal cations, An-- is an anion and 0 < x < 1. The metal hydroxides form a positively charged brucite-like layers, with the intercalated anions providing charge balance.  However, agglomeration of the LDH platelets leads to low surface area dense "stone-like" agglomerates which limits their use in many applications.  We have developed both solvent dispersion and core@shell approaches to avoid the agglomeration of the LDH platelets. For example, our Aqueous Miscible Organic Solvent Treatment (AMOST) process can create highly dispersed LDH-based materials consisting of nanosheet dispersions. This process produces exposed active sites with high surface areas and porosity. It is now possible to tailor these materials to a wide range of novel applications such as solid CO2 sorbents and heterogeneous catalysis.    This event is open to final year undergraduate project students, MSc students, PhD students, post-doctoral research associates and academic staff. https://events.st-andrews.ac.uk/events/school-of-chemistry-colloquium-professor-dermot-ohare-oxford-university/
