Magnesium Hydroxide Dehydroxylation: In Situ Nanoscale Observations of Lamellar Nucleation and Growth
Source abstract
Abstract
Lamellar dehydroxylation mechanisms are important in understanding highly reactive nanocrystal oxide formation as well as a variety of applied lamellar hydroxide reaction processes. These mechanisms have been observed for the first time via in situ nanoscale imaging for the prototype lamellar hydroxide: Mg(OH) 2 . Environmental-cell, dynamic high-resolution transmission electron microscopy was combined with advanced computational modeling in discovering that lamellar nucleation and growth processes govern dehydroxylation. The host lamella can guide the formation of a solid solution series of lamellar oxyhydroxide intermediates en route to oxide formation. This investigation opens the door to a deeper, atomic-level understanding of lamellar dehydroxylation reaction processes, nanocrystal oxide formation, and the range of potential new intermediate materials and third component reaction pathways they can provide.

Exponentially increasing atmospheric CO2levels and their potential adverse environmental consequences (e.g., global warming) have spurred substantial interest in the capture and sequestration of stationary source CO2emissions, that is, CO2sequestration.13Unlike other potential CO2sequestration technologies that offer long-term storage (e.g., ocean and geological sequestration), mineral sequestration provides permanent CO2disposal through the formation of geologically stable mineral carbonates, such as magnesite, MgCO3.14-17Mg-rich layered hydroxide minerals, such as brucite and the serpentines, offer a class of materials that can potentially address this issue by providing permanent, low-cost CO2sequestration via carbonation reaction engineering. Enhancing their carbonation reaction rates is key to lowering process cost, as longer reaction times dramatically increase cost.15-17This is the primary focus of the CO2Mineral Sequestration Working Group managed by the U.S. Department of Energy, consisting of members from the Albany Research Center, Arizona State University, Los Alamos National Laboratory, the National Energy Technology Laboratory, and Science Applications International Corporation. The potential of serpentine carbonation as a viable CO2mineral sequestration technology has been recognized in the formation of the Zero Emission Coal Alliance, an alliance of researchers from Los Alamos National Laboratory and U. S. and Canadian coal suppliers and utilities.
