    Abstract: 本碩士論文用密度泛函理論(Density Functional Theory)搭配基底函數(basis set)做計算,我們使用B3LYP/6-311++G(3df,2p)做結構最佳化,單點能量則使用CCSD(T)/aug-cc-PVQZ//B3LYP/6-311++G(3df,2p) 去計算,含有Pd金屬的結構則再加入SDD basis set進行計算,用以探討週期表第一列過渡金屬的氫化物PdH+與NH3和H2O的氣相反應,研究產生氫氣的各種可能反應機制,並繪製反應位能曲線圖(PES)。
    本實驗分成以下兩個部分進行研究:(1) [MH+] (M=Pd) + NH3的反應機構研究探討,以及(2) [MH+] (M=Pd) + H2O的反應機構研究探討。其計算結果顯示,在過度金屬離子上加了一個hydrogen ligand的反應物 [MH+] (M=Pd)會先和NH3、H2O等分子形成複合物(Complex),經由過渡狀態(Transition state),使NH3、H2O的N-H、O-H鍵斷裂,並和金屬上的H結合產生氫氣,最後在進行脫氫反應得到氫氣。
