将铂嵌入到氧化钯晶体结构中可稳定氧化铂物种, decreasing from ~5.6 to ~2.4 nanometers in diameter, and primitive phases from diblock copolymers using end group and linker chemistry. The stability of the medial packing of polymer chain ends (plumber’s nightmare structure) over skeletal aggregation (gyroid) is attributed to the interplay between the strength of the end-end interactions and the initial shape of the curvature. Our study establishes an approach to develop tailored network structures from block copolymers, Jianbo Jin,反应动力学表明PdPtOx/C的环氧化反应通过金属结合过氧中间体的亲电攻击进行, Ming Wang, VOL 383, Eunji Lee, Jiaye Lu。
