The oxidation of reduced products of CO2 on Sb-Pb-Pt/GC yielded current peaks at arrowd - 0.08, 0.2 and 0.3 V, while the oxidation of reduction products on a nm-Pt/GC electrode gave rise a current peak near 0.4 V. The in situ FTIR spectroscopic studies confirmed at a molecule level ...
鉴于此,NatureCommunications上发表了一篇题为“In-situ spectroscopic probe of the intrinsicstructure feature of single-atom center inelectrochemical CO/CO2 reduction tomethanol”的文章。在本工作中,通过将酞菁钴锚定在多壁碳纳米管上,开发了一种配位结构明确的钴单原子催化剂模型,并以此为平台采用原位X射线吸收...
