A generic method for conductive film coating of minerals and acid-sensitive materials by antimony-doped tin oxide (ATO) is introduced. The coating was performed from a hydrogen peroxide stabilized stannate and antimonate precursor solution. This is the first demonstration of ATO coating from an organic ligand-free solution. Uniform coating of different clays and other irregular configurations by monosized 5 nm ATO particles was demonstrated. The deposition mechanism and the observed preference for mineral surface coating over homogeneous agglomeration of the tin oxide particles are explained by a hydrogen peroxide capping mechanism and hydrogen bonding of the hydroperoxo nanoparticles to the H(2)O(2)-activated mineral surfaces.
一种通过掺锑氧化锡(ATO)对矿物和酸敏材料进行导电膜涂层的通用方法。该涂层是由过氧化氢稳定的锡酸盐和锑酸盐前体溶液完成的。这是首次从无有机配体的溶液中展示 ATO 涂层。通过单分散的 5nm ATO 颗粒均匀地涂覆不同的粘土和其他不规则结构得到了证明。通过过氧氢封端机制和过氧氢纳米粒子与 H₂O₂激活的矿物表面的氢键作用,解释了沉积机制和观察到的对矿物表面涂层的偏好,而不是氧化锡颗粒的均匀团聚。
