金属氧化物功能化纳米材料在生物医学、催化和吸附等领域的应用引起了广泛的研究兴趣。然而，实现高分散性和高含量的金属氧化物物种的一般化官能化方法很少报道。在这项研究中，开发了一种新的三维纳米海绵（3D-NS）启用策略来应对这一挑战。代替如在常规方法中所进行的将金属物质直接改性到纳米颗粒上，通过填充富含金属锚的甲阶酚醛树脂，将纳米颗粒的“空”孔创造性地转化为“海绵状”3D纳米空间，这有效地容纳高含量的金属物质并在制造过程中保持其高度分散的状态。这种策略是通用的，以实现不同的单一和二元金属组合物的高度分散的金属官能化。作为示范，从该策略衍生的高度分散的铜物种显示出优异的芬顿样催化活性和增强的癌细胞抑制性能。这些发现为金属功能化纳米材料的高级应用开发提供了新的理解和有用的工具。
Nanomaterials functionalized with metal oxide species have aroused broad research interest in biomedical, catalysis and adsorption applications. However, a generalized functionalization approach achieving both high dispersity and high content of metal oxide species is rarely reported. In this study, a novel three-dimensional nanosponge (3D-NS) enabled strategy is developed to tackle this challenge. Instead of directly modifying metal species onto nanoparticles as performed in conventional approaches, the "empty" pores of nanoparticles are creatively converted into a "sponge-like" 3D nanospace by filling up with resoles rich in metal anchors, which efficiently accommodate high content metal species and maintain their highly dispersed state during the fabrication process. This strategy is generic to achieve highly dispersed metal functionalization of different single and binary metal compositions. As a demonstration, highly dispersed copper species derived from this strategy show excellent Fenton-like catalytic activity and enhanced cancer cell inhibition performance. These findings provide new understanding and useful tools for the development of metal functionalized nanomaterials for advanced applications.
