摘要

本研究採用低成本、低毒性、和易合成的實驗製程，利用常壓電漿輔助化學氣相沉積製作出高密度、高比表面積的氧化鋅奈米片狀結構及氧化鋅/銅氧化物異質接面於光電化學產氫之應用。氧化鋅奈米片狀結構
的太陽能轉換氫氣效率於0.6 V (vs. RHE)電壓下其數值為0.01%。
為了提升氧化鋅奈米片於光電化學產氫的效率，於氧化鋅奈米片上鍍覆銅氧化物之顆粒，形成NP 接面，提升光電化學產氫性能。氧化鋅/銅氧化物異質接面之太陽能轉換氫氣效率於0.6 V (vs. RHE)電壓下其數值為0.21%，高過氧化鋅21倍。

In this study, ZnO nanosheet structures and copper oxide/ZnO heterojunctions
were prepared by means of a cost-effective, low-toxicity, and easier synthesize
experimental process was used to fabricate high-density, high-surface-area by
atmospheric pressure plasma process-assisted chemical vapor deposition for the
application of photoelectrochemical hydrogen generation. The highest solar-tohydrogen
conversion efficiency of the ZnO nanosheet structure was 0.01% at 0.6 V(vs. RHE), respectively.
To improve the efficiency of photoelectrochemical hydrogen generation of ZnO nanosheets, copper oxide nanoparticles was decorated by the surface of ZnO nanosheets to form a NP junctions to improve the photoelectrochemical hydrogen generation performance. The highest solar-to-hydrogen conversion efficiency of the copper oxide/ZnO heterojunctions was 0.21% at 0.6 V (vs. RHE), which were 21 times more than ZnO.
