Novel approach for synthesis of boehmite nanostructures and their conversion to aluminum oxide nanostructures for remove Congo red

The impact of nanocrystallite size and shape on phase transformation: Application to the boehmite/alumina transformation

“…To improve the catalyst support properties, the boehmite crystallite size, shape, sample porosity, and surface area are optimized through the preparation conditions. Numerous advanced methods have been developed to prepare boehmite particles with various shapes and to recover after activation the final material with the desired surface properties [10,11]. During the final calcination step, c-AlOOH is converted into the desired alumina phase.…”

A solid-state chemical method for synthesizing MgO nanoparticles with superior adsorption properties

“…[9][10][11][12] Owing to high efficiency, speed, and low energy requirements, adsorption is a universal and advantageous approach to removing dyes from aqueous systems among various other methods. [13][14][15] However, ordinary adsorbents have a limited adsorption capacity and low adsorption rate. 16 As a traditional material used in wastewater treatment, MgO is an indispensable substance that is low-cost, ecofriendly, nontoxic, and economical.…”

The solvothermal synthesis of γ-AlOOH nanoflakes and their compression behaviors under high pressures

“…Through delicate control of the reaction parameters, such as the pH value, the temperature, the time of processing, and the selection of precursors, solvents, and surfactants, etc., tuning of the dimension, size and shape of the target g-AlOOH nanomaterials as desired may be achieved. [6][7][8][9][10][11][12][13][14][15][16] In addition to its technological importance, g-AlOOH is also of considerable relevance in high pressure studies. As a mineral with intrastructural hydroxyl groups, the structure and stability of boehmite under high pressures is not only relevant for the investigation of geophysical and geochemical processes in the Earth's crust and the upper mantle, but also for the preparation of new materials with specic properties via high pressure/high temperature techniques.…”
