In Situ Grown Heterostructure Based on MOF-Derived Carbon Containing n-Type Zn–In–S and Dry-Oxidative p-Type CuO as Pseudocapacitive Electrode Materials

ACS Energy Letters, Journal Year: 2023, Volume and Issue: 8(4), P. 1887 - 1895

Published: March 23, 2023

The rational design of highly oriented and integrated heterostructures based on metal–organic framework (MOF)-derived carbon containing n-type metal chalcogenides (Zn–In–S/C) polyhedron p-type oxide (CuO) nanowires was proposed. CuO were used as a stable scaffold to grow MOF-derived Zn–In–S/C. controlled in situ fabricated Zn–In–S/C@CuO provided p–n heterojunction which enhanced the charge transfer, hence providing an improved overall electrochemical performance over its MOF bare counterpart. Coupled with density functional theory (DFT) calculations, enhancement conductivity heterostructure further verified. symmetric supercapacitor device delivered energy 7 Wh kg–1 at power 4 kW kg–1. Overall, theoretical experimental investigation grown better cycling stability activity could be useful asset for storage devices.
