The swelling and exfoliation behavior of protonated layered oxides using an organo-phosphonium base, tetrabutylphosphonium hydroxide (TBPOH), was examined for the first time. The action of the aqueous solution induced massive interlayer expansion up to ~100-fold. The swollen crystals were immediately broken and completely exfoliated into unilamellar nanosheets in 1-2 h by shaking.
首次研究了使用有机鏻碱四丁基氢氧化鏻(TBPOH)对质子化层状氧化物的膨胀和剥离行为。水溶液的作用导致层间大量膨胀,膨胀倍数高达约100倍。通过摇晃,膨胀后的晶体在1-2小时内立即破碎并完全剥离成单层纳米片。
