ZIF-67 Derivative Decorated MXene for a Highly Integrated Flexible Self-Powered Photodetector

Abstract

The rapid development of portable and wearable electronics has promoted the integration of multifunction techniques. Although flexible energy storage systems have been successfully investigated, the compact configuration with photodetector and energy storage components has received less attention. As a new member of the 2D material class, MXene exhibits remarkable electronic and optical properties. Here, through the intentional introduction of ZIF-67 derivatives deposited on the Mo2CT x nanosheets, the synthesized Co-CoO x /NC/Mo2CT x heterostructure not only provided a straightforward pathway for photogenerated electrons to transport but also enhanced the structural stability of Mo2CT x , leading to a high responsivity and short rise/decay time under the illumination of simulated light in the photoelectrochemical (PEC) configuration. The integrated flexible device based on a zinc ion battery and Co-CoO x /NC/Mo2CT x heterostructure shows outstanding photodetection function and retains the intrinsic charge/discharge behaviors, which could monitor 1 day sunlight changes in real time. The paradigm presented here paves the way for realizing the development of miniaturization and multifunction toward next-generation portable and wearable technologies.

MXenes for Bioinspired Soft Actuators: Advancements in Angle-Independent Structural Colors and Beyond

“…By combining the unique properties of MXenes with other functional materials, researchers can develop soft actuators that exhibit complex, programmable behaviors, such as shape morphing or temperature-responsive actuation. Furthermore, MXenecentered soft actuators have the capability to harvest energy from their surroundings, enabling self-powered and autonomous systems [88][89][90]. By integrating energy harvesting mechanisms, such as piezoelectric or triboelectric generators, into MXene-based soft actuators, researchers know how to create self-sustainable devices that can harvest energy from mechanical or environmental sources.…”
