【発明の名称】層状遷移金属ジカルコゲナイド及びその製造方法
Document Type and Number:
Japanese Patent JP2930344
Kind Code:
B2
Abstract:
Compositions of the formula MX2:Y, wherein MX2 is a layer type transition metal dichalcogenide, M is a metal selected from the group consisting of niobium, tantalum, molybdenum and tungsten, X is a chalcogen selected from the group consisting of sulfur and selenium and Y is a material located between layers of MX2. The compositions may be prepared by the steps of first forming a suspension of the MX2 in a body of water. A liquid which is immiscible with water is added to the suspension. The suspension and immiscible liquid are agitated together to form a temporary emulsion. The emulsion is allowed to rest until the water and the liquid separate with an interface therebetween. A sheet-like composition of MX2:Y forms at the interface. Preferably, the MX2 is in exfoliated, singular molecular thickness layers suspended in the water.
