Abstract

This study introduces a novel "solvent-pair surfactants" enabled assembly (SPEA) method for synthesizing functional mesoporous metal oxides (mMOs). The method utilizes a binary solvent system (e.g., DMF/H₂O) to overcome limitations of traditional host-guest interactions in assembling polyoxometalates (POMs) and amphiphilic block copolymers (AB copolymers). The resulting mMOs exhibit ordered mesostructures with tunable pore sizes and compositions, demonstrated by the synthesis of nitrogen-doped ε-WO₃ with superior acetone sensing performance. The SPEA approach offers a general and versatile route for designing mMOs with diverse structures and compositions for various applications.
