Title:
錫ドープ光触媒式ホルムアルデヒド感知材料およびその製造方法、ならびにホルムアルデヒドセンサ
Document Type and Number:
Japanese Patent JP2018530740
Kind Code:
A
Abstract:
本発明は、酸化亜鉛ナノ粒子および錫系添加剤を含む錫ドープ光触媒式ホルムアルデヒド感知材料およびその製造方法、ならびにホルムアルデヒドセンサに関する。該材料を作製する際は、まず、予め合成された酸化亜鉛ナノ粒子を錫塩溶液に均一に分散させた溶液Ａを得て、次に、溶液Ａを撹拌しながら溶媒を全て蒸発させた沈殿物Ｂを得て、その後、沈殿物Ｂを高温下で焼結処理し、光触媒式ホルムアルデヒド感知材料である産物Ｃを得る。本方法は、低コスト、高感度、高選択性の光触媒式ホルムアルデヒド感知材料を提供し、ホルムアルデヒドの検知下限値を０.１ｐｐｍにまで下げると共に、材料によるエタノール選択性を高めることができる。
