本研究以氯化鋅、氯化銦與硫乙醯胺作為反應物，利用水熱法成功於FTO基板上成長直立型硫化銦鋅奈米片陣列(ZIS)，並進一步將ZIS試片置於空氣或氬氣下進行400 ℃後處理，分別得到ZIS-Air400與ZIS-Ar400。首先透過掃描式電子顯微鏡(SEM)對其表面形貌進行分析，發現三種試片之奈米片陣列皆均勻分佈於FTO表面且整體膜厚皆約為250 nm。由拉曼散射光譜分析可知，ZIS試片中除六方晶系硫化銦鋅外，亦有六方晶系硫化銦存在。空氣中後處理過之ZIS-Air400存有較弱之六方晶系硫化銦鋅訊號，且未能觀察到六方晶系硫化銦。於氬氣中後處理之ZIS-Ar400則表現出增強的硫化銦鋅訊號。另外從TEM分析中可以發現三者皆為多晶結構，且ZIS-Air400奈米片中存在菱形晶系氧化銦鋅構成之區域。XRD分析結果亦與HR-TEM分析結果互相吻合。因此綜合拉曼散射光譜、HR-TEM、XRD結果可以推知，ZIS與ZIS-Air400均為混合相構成之奈米片陣列，而ZIS-Ar400則為單一六方晶系硫化銦鋅所構成。
　　比較樣品二氧化碳光轉換結果，經十小時光轉換反應後，ZIS-Air400檢測到19.2 µmol/gcat一氧化碳與38.1 µmol/gcat乙醛生成。而ZIS-Ar400在照光十小時反應後，量測到5.5 µmol/gcat之一氧化碳與19.1 µmol/gcat之乙醛產量。最後根據計算結果推測，在經過不同氣氛熱處理後之樣品，能有效利用其光生電子進行二氧化碳光轉換反應，兩者之選擇率皆接近100%，並且在本研究最後的部分提出了可能的載子遷移機制。

In this work, vertical zinc indium sulfide nanosheet array have been successfully fabricated on an FTO substrate. The as-prepared nanosheet array were further annealing in different atmospheres to change their crystallinity and crystal structure. The photocatalysts were employed to carbon dioxide photoconversion under batch system with a one sun simulator as the light source. GC-BID and GC-FID were used to detect the products such as carbon monoxide, hydrogen and some hydrocarbon components. According to the results, after annealing with air and argon atmospheres, the selectivity for carbon dioxide photoconversion was close to 100%.
