초록
층상 구조의 유기-무기 복합 소재 Cu2(OH)3(CH3COO)·H2O에 마이크로파를 조사하면서 Cu2O와 Cu를 합성하였다. 에틸렌 글리콜에서는 Cu2(OH)3(CH3COO)·H2O이 환원이 되어서 Cu 금속이 형성되는 반면에, 수용액에 글루코오스를 넣으면 Cu2(OH)3(CH3COO)·H2O이 환원이 되어 Cu2O가 형성되었다. 마이크로파 조사 시간과 글루코오스의 농도가 Cu2O의 입자의 생성과 성장에 미치는 영향을 확인하였다. 마이크로파의 조사 시간이 길어질수록 Cu2O의 입자는 수 mm의 구형에서 40 nm의 지름을 가진 나노 선으로 변함을 확인하였다.1. 서 론
Abstract
Cu2O and Cu have been synthesized from the layered organic-inorganic hybrid, Cu2(OH)3(CH3COO)?H2O, assisted by microwave irradiation. Cu2O is formed in aqueous glucose solution, while metallic Cu is formed in ethylene glycol by reduction of Cu2(OH)3(CH3COO)?H2O. The influence of microwave irradiation time and concentration of glucose on Cu2O particles formation and growth has been examined. The morphologies of Cu2O particles change from spheres with a few mm size to nanowires with diameter of 40 nm as increasing the microwave irradiation times.Key words Cu2O, Metallic Cu, Organic-inorganic hybrid, MicrowaveCu2(OH)3(CH3COO)·H2O로 부터 마이크로파를 이용한 Cu2O와 Cu의 합성송하철, 허영덕?단국대학교 화학과, 서울, 140-714(2006년 7월 3일 접수)(2006년 7월 26일 심사완료)
