Fe3+ facilitating the response of NiO towards H2S†
Abstract
Fe2O3-loaded NiO nanoplates have been successfully prepared by a facile method by immersing NiO nanoplates in aqueous Fe(NO3)3 solution and annealing the corresponding as-immersed NiO nanoplates. When studied as sensing materials, the as-fabricated Fe2O3-loaded NiO nanoplates display enhanced response towards H2S in comparison with pure NiO nanoplates.
