: CO is introduced as a confining agent to regulate the anisotropic growth of unique 2D structure. The single-crystalline Rh nanosheets have a thickness of three to five atomic layers and tunable edge length ranging from 500 to 1300 nm. By understanding the formation mechanism, surface-clean Rh nanosheets are also prepared and display better catalytic performance that their surfactant-capped nanosheets.
引入一氧化碳作为限制剂来调控独特二维结构的各向异性生长。单晶铑纳米片的厚度为三到五个原子层，边缘长度可调，范围在500到1300纳米之间。通过了解其形成机制，还制备出了表面清洁的铑纳米片，并且它们表现出比表面有表面活性剂包覆的纳米片更好的催化性能。
