Self-Assembled Y2O3/Y(OH)3 Heterojunction Nanosheets Hydrogel for Efficient Metal Resources Recovery.
Hydrogels are innovative and efficient adsorbent for metal resource recovery owing to their three-dimensional porous network, abundant functional groups, and exceptional hydrophilicity. However, the fabrication of stable metal oxide hydrogels in aqueous media is severely hindered by rapid metal ion hydrolysis and unsta...
