Abstract Scope Aluminosilicate geopolymer is a low-temperature ceramics with an immense potential in sustainability applications. Recent innovations in geopolymer synthesis have enabled previously unforeseen levels of control over the nanoscopic morphologies and porosity and have demonstrated that the resulting nanomaterials can show performances far superior to other classes of materials. This talk will illustrate some of these advances with examples relevant to sustainability applications. For example, nanoporous geopolymer materials could be produced and used as an excellent arsenic absorbent for ground water purification and as a highly effective biodiesel catalyst. High-structure geopolymer nanoaggregates can be synthesized with controlled zeolicity for polymer nanocomposite applications with excellent energy-saving performances. Highly-crystalline hierarchical zeolites have been discovered to show an exceptional CO2 capacity, sorption kinetics, selectivity and regeneration capability essential for cost-effective CO2 separation. Superior ion exchange kinetics of the material has been observed for silver-ion zeolite with a superb antibacterial efficacy against antibiotics-resistant MRSA bacteria.
