Photoelectrochemical Water Splitting Using GaN [PDF]

Journal of the Korean Electrochemical Society, 2014
본 총설은 질화 갈륨(GaN)을 이용한 광전기화학적 물분해 연구에 대해 정리하였다. GaN는 화학적으로 안정하고 에너지 띠간격 조절이 자유롭다는 장점으로 최근 물분해를 위한 새로운 광전극 물질로 연구되고 있다. 다른 화합물 반도체 물질은 강산 혹은 강염기 전해액에 의해 쉽게부식되기 때문에 광산화전극(photoanode)으로는 사용이 어려운 반면, n형 GaN는 뛰어난 안정성덕분에 산화 분위기의 산소 발생 전극으로도 활용이 가능하다. 또한, 최근에는 p형 GaN을 환원전극으로 이용한 광전극에 대한 연구도 보고되었다.
