A Cu2B2 monolayer with planar hypercoordinate motifs: an efficient catalyst for CO electroreduction to ethanol

J. Mater. Chem. A, 2020, Advance Article
DOI: 10.1039/D0TA02471F, Paper
Jingjing Jia, Haijun Zhang, Zhongxu Wang, Jingxiang Zhao, Zhen Zhou
By means of first-principles computations, we identified that metallic Cu2B2 monolayer with planar heptacoordinate motifs could effectively reduce CO to ethanol through the “carbene” mechanism with a low limiting potential and a small barrier for C–C coupling.

Semiconducting polymer contributes favorably to the Seebeck coefficient in multi-component, high-performance n-type thermoelectric nanocomposites

J. Mater. Chem. A, 2020, Advance Article
DOI: 10.1039/D0TA02388D, Paper
Junhui Tang, Ruisi Chen, Lidong Chen, Guillermo C. Bazan, Ziqi Liang
n-Type Co NWs/N2200 TENCs yield a high S, mainly from the semiconducting polymer, yet σ is limited by poor connectivity between inorganic and organic domains. By adding flexible n-doped SWCNTs to yield more conductive paths, σ and mechanical bendability are greatly enhanced.
