Self-supported zinc carbonate hydroxide (Zn5(CO3)2(OH)6) film was fabricated using an air-liquid interface. ZnO film was firstly prepared from an aqueous solution containing zinc nitrate hexahydrate and ethylenediamine at 60 oC for 6 h and 25 oC for 42 h. ZnO was dissolved gradually as the solution temperature decreased. Zn5(CO3)2(OH)6 was then crystallized by ion supply from the solution to form a film at the air-liquid interface for 1 month. The resultant film was a single phase of Zn5(CO3)2(OH)6 and an assembly of thin sheets. The film had different morphologies on the air side and on the liquid side, reflecting the direction of crystal growth of thin sheets. The air-liquid interface provided a novel reaction field for crystal growth.
