    heterogeneous reaction 是一個化學術語,指非均相反應(或多相反應),即反應涉及兩種或多種不同物相(如固-氣、固-液、液-液等)或在界面(如催化劑表面)進行的化學反應。以下是詳細解釋:


    1.定義與特點


    2.常見類型


    3.與均相反應的對比


    4.應用場景


    5.典型反應式示例

    以固體催化劑(如Pt)表面發生的氫氣與氧氣反應生成水為例: $$ 2H_2(g) + O_2(g) xrightarrow{Pt} 2H_2O(l) $$ 說明:反應物為氣相,催化劑為固相,反應在Pt表面進行。


    如需進一步了解具體反應機制或應用案例,可參考化學教材或專業文獻。
