From: Understanding the mechanism of Nb-MXene bioremediation with green microalgae

HRTEM images show the morphology of oxidized (a) SL Nb2CTx and (b) SL Nb4C3Tx MXenes, results of XPS analysis showing (c) the composition of oxide products after remediating, component peak-fitting of XPS spectra for (d–f) SL Nb2CTx and (g–i) SL Nb4C3Tx after remediation with green microalgae.
