Ultralow and Selective Infrared Emission from MXenes [PDF]
arXiv, 2021 Low and selective infrared emission materials are necessary for next generation thermal technologies, including passive heating, infrared identification, and photothermal conversion. Here, we report on the intrinsic infrared radiation properties of three MXenes: Ti3C2Tx, Ti3CNTx, and V4C3Tx.

Understanding the effect of MXene in a TMO/MXene hybrid catalyst for the oxygen evolution reaction
npj 2D Materials and Applications, 2023 AbstractVery recently, it has been reported that mixed transition metal oxide (TMO)/MXene catalysts show improved performance over TMO only catalysts for the oxygen evolution reaction (OER). However, the reasoning behind this observation is unknown. In this work mixed Co(OH)2/Ti3C2Txwere prepared and characterized for the OER using ex situ and operando

Modifications of MXene layers for supercapacitors [PDF]
Nano Energy, 2020 Abstract The re-stacking of Ti3C2Tx-MXene layers has been prevented by using two different approaches: a facile hard templating method and a pore-forming approach. The expanded MXene obtained by using MgO nanoparticles as hard templates displayed an open morphology based on crumpled layers.
