Graphdiyne (GDY), a novel kind of two-dimensional carbon allotrope consisting of sp- and sp(2)-hybridized carbon atoms, is found to be able to serve as the reducing agent and stabilizer for electroless deposition of highly dispersed Pd nanoparticles owing to its low reduction potential and highly conjugated electronic structure. Furthermore, we observe that graphdiyne oxide (GDYO), the oxidation form of GDY, can be used as an even excellent substrate for electroless deposition of ultrafine Pd clusters to form Pd/GDYO nanocomposite that exhibits a high catalytic performance toward the reduction of 4-nitrophenol. The high catalytic performance is considered to benefit from the rational design and electroless deposition of active metal catalysts with GDYO as the support.

氧化石墨炔作为具有高催化活性的 Pd 簇的化学沉积的优良基材

石墨炔 (GDY) 是一种由 sp 和 sp(2) 杂化碳原子组成的新型二维碳同素异形体，被发现能够用作化学沉积高度分散的 Pd 纳米粒子的还原剂和稳定剂低还原电位和高度共轭的电子结构。此外，我们观察到氧化石墨烯 (GDYO)，GDY 的氧化形式，可用作超细 Pd 簇的无电沉积以形成 Pd/GDYO 纳米复合材料的优良基材，该复合材料对还原 4-硝基苯酚。高催化性能被认为受益于以GDYO为载体的活性金属催化剂的合理设计和化学沉积。
