From: Micro-meso-macroporous channels finely tailored for highly efficient moisture energy harvesting
a SEM images of cross-sectional pores inside different salting-out hydrogels. b SEM images of abundant pores inside sodium citrate salting-out hydrogel skeleton sidewall (top sectional view), inset: cross-sectional view. c Surface SEM images and EDS elemental characterization of modified P-MXene membranes. After modification, new elements of N and Si were added. d The peak fitting results of N1s in the X-ray photoelectron spectroscopy (XPS) analysis of modified P-MXene nanosheets. e ζ-potentials of N-MXene and P-MXene suspensions at different pH. f X-ray diffractograms (XRD) of gels prepared with and without salting out. g Fourier transform infrared (FTIR) spectra of gels prepared with and without salting out. h Compressive strain test curves of gels prepared with and without salting out. The source data are available in the “Data availability” section.
