Ionic liquid-assisted synthesis of mesoporous α-Ga2O3 hierarchical structures with enhanced photocatalytic activity

In this article, we successfully fabricate alpha-GaOOH hierarchical structures using a facile and simple one-pot ionic liquid-assisted hydrothermal method. In addition, the as-prepared alpha-GaOOH precursor can then be converted to mesoporous alpha-Ga2O3 hierarchical structures by thermal decomposition while preserving the same morphology, which exhibit enhanced photocatalytic activity.
