摘要:
Mesoporous anatase TiO2 spheres (MATS) are elaborated via microwave-assisted rapid crystallization of hydrous TiO2 colloidal spheres (HTCS) self-template. Tuning the hydrothermal and calcination temperatures allow for textural property-controllable synthesis. The optimal MATS are demonstrated as a promising cathode material of aluminium-ion batteries (AIBs) and show superior rate and capacity performances. Their large surface area and porous structure offer a robust and interconnected scaffold for Al3+ insertion/exertion with higher reversibility. The constructed non-aqueous AIBs with RTILs el...
