Autor: Daire Tyndall, Lee Gannon, Lucia Hughes, Julian Carolan, Sergio Pinilla, Sonia Jaśkaniec, Dahnan Spurling, Oskar Ronan, Cormac McGuinness, Niall McEvoy, Valeria Nicolosi, Michelle Philippa Browne
Publikováno v: npj 2D Materials and Applications, Vol 7, Iss 1, Pp 1-11 (2023)
Abstract Very 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.

High capacity silicon anodes enabled by MXene viscous aqueous ink
Autor: Chuanfang (John) Zhang, Sang-Hoon Park, Andrés Seral‐Ascaso, Sebastian Barwich, Niall McEvoy, Conor S. Boland, Jonathan N. Coleman, Yury Gogotsi, Valeria Nicolosi
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)
Developing thick electrodes could enable high-energy-density Li-ion batteries, however, above a critical thickness, the mass transport issues become dominating. Here the authors show that MXene can serve as a conductive binder leading to thick silico

Lithium Titanate/Carbon Nanotubes Composites Processed by Ultrasound Irradiation as Anodes for Lithium Ion Batteries
Autor: João Coelho, Anuj Pokle, Sang-Hoon Park, Niall McEvoy, Nina C. Berner, Georg S. Duesberg, Valeria Nicolosi
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-11 (2017)
Abstract In this work, lithium titanate nanoparticles (nLTO)/single wall carbon nanotubes (SWCNT) composite electrodes are prepared by the combination of an ultrasound irradiation and ultrasonic spray deposition methods. It was found that a mass frac
