대기 중 이산화탄소의 재활용 기술과 재생에너지에 의한 물 분해 기술의 접목이 최근 가능해지면서 메탄올은 많은 관심을 받고 있다. 경제성이 유리하도록 메탄올 경제를 실현하기 위해서는 고활성 메탄올 합성 촉매를 제조하여야 하며, 이를 위해서는 논리적인 접근법이 필요하다. 공침법을 통해 제조하는 Cu/ZnO 기반의 촉매는 침전, 숙성, 여과, 세척, 건조, 소성, 환원 등의 복잡한 단계로 제조되며, 100년의 역사를 가지고 있음에도 불구하고 최근에야 침전 화학과 촉매 나노구조에 대한 기초적인 이해가 이루어지고 있다. 이에 본 고에서는 단계별로 합성 변수가 침전, 소성, 환원상태 물질의 물성에 미치는 영향에 대한 최근 결과들을 리뷰하고, 화학적 기억 효과라고 부르는 이들 물성들과 최종촉매의 활성 사이의 관련성을 논의하였다. 제조 변수별 설명은 메탄올 합성을 위한 Cu/ZnO 기반 고활성 촉매를 제조하는 방법에 초점이 맞추어져 있다. 논의된 합성 전략은 공침법을 기반으로 하는 타 금속 또는 금속 산화물 담지 촉매의 제조에 활용 가능할 것으로 판단된다.

In recent years, methanol has attracted much attention since it can be cleanly manufactured by the combined use of atmospheric CO<sub>2</sub> recycling and water splitting via renewable energy. For the concept of “methanol economy”, an active methanol synthesis catalyst should be prepared in a sophisticated manner rather than by empirical optimization approach. Even though Cu/ZnO-based catalysts prepared by coprecipitation are well known and have been extensively investigated even for a century, fundamental understanding on the precipitation chemistry and catalyst nanostructure has recently been achieved due to complexity of the necessary preparation steps such as precipitation, ageing, filtering, washing, drying, calcination and reduction. Herein we review the recent reports regarding the effects of various synthesis variables in each step on the physicochemical properties of materials in precursor, calcined and reduced states. The relationship between these characteristics and the catalytic performance will also be discussed because many variables in each step strongly influence the final catalytic activity, called “chemical memory”. All discussion focuses on how to prepare a highly active Cu/ZnO-based catalyst for methanol synthesis. Furthermore, the preparation strategy we deliver here would be utilized for designing other coprecipitation-derived supported metal or metal oxide catalysts.
