以柠檬酸或柠檬酸钠为还原剂与氯金酸混合得混合溶液；
(2)金胶制备
将步骤(1)所得混合溶液放置在反应池中，加热，进行化学还原反应1h制备金胶；
(3)玻璃或石英表面处理
将玻璃或石英表面用砂纸打磨，形成粗糙表面；
(4)制备三维金纳米多孔膜
将形成有粗糙表面的玻璃或石英表面浸入金胶反应24h，取出，烘干，即在玻璃或石英表面制备出三维金纳米多孔膜。
在本发明中，步骤(1)中，所述混合溶液中各组分最终浓度为：柠檬酸质量百分比为0.01％～0.2％，氯金酸质量百分比为0.01％～0.5％。
在本发明中，步骤(2)中，所述加热温度为100℃。
在本发明中，步骤(3)中，所述砂纸为60目～1200目。
在本发明中，步骤(4)中，所述烘干温度为40℃～100℃。
有益效果：
(1)本发明不需要高分子化合物等基底材料作为模板，采用固体表面自组装制备三维金纳米多孔膜，具有操作简便、低污染的特点，有效降低生产成本；
(2)本发明中所使用的原料比较容易获得，工艺方法简单，纳米膜形成无需要高分子模板参与，也不需要化学试剂将金纳米吸附在固体表面，故三维金纳米多孔膜所含杂质少、纯度高，对于分析检测方面的应用极为有利。
