摘要
以氨基酸为还原剂及配位剂,在碱性溶液中通过水热还原二价铜离子,制备了不同形貌的氧化亚铜微晶。考察了氨基酸对氧化亚铜微晶结构、尺寸、形貌的影响,提出了氧化亚铜微晶在水热条件下的可能形成机理,结果表明氨基酸是良好的形貌调节剂。以亚甲基蓝为探针分子,对所制备的氧化亚铜微晶的光催化性能进行了研究,发现其催化性能与形貌间存在着密切联系。
Cuprous oxide micro/nanostructures with various morphologies were successfully synthesized by using amino acids to reduce the coordinated Cu2~ in basic solution by hydrothermal method.The effects of amino acid reducing agents on the structure, size,and morphologies of cuprous oxide microcrystals were investigated,and the possible formation mechanism of cuprous oxide microcrystals was proposed.Resuh showed that the amino acids exhibited good structure-directing activities. The photo-catalytic activity of as-prepared cuprous oxide microcrystal for decomposition of methyl blue was investigated,in which the morphology-dependent catalytic properties were revealed.
