复旦大学张黎明课题组--石墨炔/石墨烯异质结构:二维框架锚定单分散过渡金属酞菁用于选择性和稳定地电还原CO2

这里,展示了石墨炔/石墨烯(GDY/G) 异质结构作为 2D 导电支架来锚定单分散钴酞菁 (CoPc) ,并用于 CO2还原,表现出可观的活性、选择性和耐久性。一系列表征,例如X 射线吸收光谱 (XAS) 和密度泛函理论 (DFT) 计算揭示了 GDY 和CoPc之间的强相互作用,高表面积,丰富的反应中心和电导性,协同造就了优越的电催化性能。电化学测量显示,在 H 电池中12 mA cm−2局域电流密度时,CO的FE为 96%,液体流通池中100 mA cm-2电流密度时,CO的FE高达97%,超过24小时的耐久性。CoPc在-1.0 V vs RHE电位下其周转频率达到 37 s−1,优于大多数报道的酞菁和卟啉基电催化剂。利用GDY/G 异质结构作为支架可以进一步扩展到其他有机金属配合物当中。
