Synthesis of small Fe2O3 nanocubes and their enhanced water vapour adsorption–desorption properties

Abstract

It is of great importance to develop humidity-buffering materials and thus to improve indoor environments. Uniform Fe₂O₃ nanocubes with an average pore size distribution of 8.48 nm exhibit superior water adsorption–desorption ability, arising from the appropriate pore size distribution around the condensation critical radius. This finding can provide a novel strategy to design and prepare new humidity-buffering nanomaterials.
