Facile and accelerated production of RuO₂ monolayers via a dual-step intercalation process

Abstract

RuO2 monolayer nanosheets were prepared by a rapid and efficient dual step exfoliation process.

Long-range ordering of two-dimensional wide bandgap tantalum oxide nanosheets in printed films

“…24 Yet, its quantitative value is significantly higher, and it is also considerably higher than the activation energy of 27.3 kJ mol À1 for the exfoliation of RuO 2 . 16 The sequence in apparent activation energies of exfoliation, i.e. graphene o RuO 2 nanosheets o TaO 3 nanosheets is in qualitative good agreement with the differences in the cohesive binding energies between graphene nanosheets, which are dominated by van der Waals forces, and the stronger electrostatic interactions between H + /RuO 2 À and H + /TaO 3 À , respectively.…”

“…14 TaO 3 nanosheets exhibit a relatively high charge density of À1.6 C m À2 on their basal plane, while much more easily to exfoliate lepidocrocite-type titanate nanosheets show a charge density of À0.99 C m À2 , 15 and RuO 2 nanosheets have a charge density of À0.46 C m À2 , calculated on the basis of data from ref. 16 For TaO 3 this results in stronger Coulombic interactions between the interlayer cations and the TaO 3 À layers. Lower charge densities lead to a weaker electrostatic force between the layers, whereas higher charge densities require more energy to exfoliate a layered intercalation phase.…”

Modulation of Conductivity and Contact Resistance of RuO2 Nanosheets via Metal Nano-Particles Surface Decoration

“…The interplanar d-spacing in the electron diffraction (ED) pattern and inter-atomic distance in STEM were equivalent to the d-spacing between the monolayer RuO 2 nanosheets obtained from our calculations [ 28 ]. The synthesis and exfoliation of RuO 2 nanosheets were described in detail elsewhere [ 28 , 29 , 31 ].…”
