A non-noble metal-based bifunctional Fe–Ni/MMT nanocomposites exhibit excellent H₂ generation capability from the methanolysis of NaBH₄ at a rate of 16,200 mL min⁻¹ g⁻¹_Fe–_Ni with 10%Fe–Ni loading on MMT support. Moreover, the evolved H₂ from this catalytic process is efficiently utilized for the one-pot step-wise synthesis of secondary amines from nitrobenzene and aldehydes using NaBH₄ as a source of hydrogen at room temperature. Circumventing the reduction of aldehyde and triggering the formation of imine intermediate through sequential addition of reactants in a time dependent manner has resulted in the excellent yields for aliphatic, aromatic and heterocyclic amines (91–98%). The catalytic activity of Fe–Ni/MMT nanocomposite is ascribed to synergic association of Fe–Ni NPs, Lewis and Brønsted acidity as well as adsorptive nature of MMT. Thus, a simple, facile and greener route is developed for the synthesis of secondary amines with an efficient H₂ generation non-noble metal catalyst and easily accessible H-donor at room temperature.

一种基于非贵金属的双功能Fe–Ni / MMT纳米复合材料，通过NaBH ₄的甲醇分解，以16,200 mL min ^-1  g ^-1 _Fe – _Ni的速率表现出出色的H ₂生成能力，MMT负载率为10％支持。此外，从该催化过程中析出的H ₂可有效地用于利用NaBH ₄从硝基苯和醛一步一步合成仲胺的过程中在室温下作为氢的来源。通过以时间依赖的方式依次添加反应物来避免醛的还原并引发亚胺中间体的形成，已导致脂族，芳族和杂环胺的优异收率（91-98％）。Fe-Ni / MMT纳米复合材料的催化活性归因于Fe-Ni NPs，路易斯和布朗斯台德酸度的协同结合以及MMT的吸附性。因此，开发了一种简单，简便且绿色的途径，用于在室温下用高效的H ₂生成非贵金属催化剂和易于得到的H供体合成仲胺。
