Abstract

Boehmite (γ-AlOOH) and gibbsite (α-A;(OH)₃) are important archetype (oxy)hydroxides of aluminum in nature that also play diverse roles across a plethora of industrial applications. As a consequence, highly precise synthesis of these pure phases with controlled particle size, shape and properties towards an end of tunable chemical behavior is an important ongoing research and development enterprise. We recently reported flexible and additive-free synthesis strategies, along with detailed growth mechanisms, that produce morphologically well-defined nanoplates of controllable size in high yield. The present study describes bulk and surface characteristics of these novel materials in comprehensive detail, using a collectively-sophisticated set of experimental capabilities, including a range of conventional laboratory solids analyses as well as national user facility analyses such as synchrotron X-ray absorption and scattering spectroscopies, and small angle neutron scattering. These materials and their integrated characterization have been developed as a part of the fundamental science campaign of the U.S. Department of Energy's Energy Frontier Research Center named Interfacial Dynamics in Radioactive Environments and Materials (IDREAM), which focuses on understanding the complex chemistry of aluminum speciation and solids reactive behavior in the extreme conditions of highly concentrated aqueous electrolytes including the effects of a radiation field.
