Herein, we report Co−Cu bimetal integrated phosphate catalyst, unexpectedly enables ultrafast catalytic reduction of 4‐nitrophenol within 40 s by right of the synergy of bimetals. Impressively, the reaction induction period observed might indicate the deoxygenation of metal oxide units in phosphate, however, which was eliminated using bimetal (Co−Cu) phosphate at 30 °C and 40 °C. The calculated reaction rate constant is 4.78 min⁻¹ at 30 °C, which exhibits a very high superiority compared to other reported cobalt‐based catalysts. This study offers the possibility for the ultrafast catalytic reduction and elimination of toxic nitrophenol using efficient‐cost transition metal catalysts.

磷酸盐中双金属Co-Cu产生的协同作用使硝基苯酚还原具有超快的催化氢化活性

在本文中，我们报道了Co-Cu双金属集成磷酸盐催化剂，出乎意料地通过双金属的协同作用，能够在40 s内超快催化还原4-硝基苯酚。令人印象深刻的是，观察到的反应诱导期可能表明磷酸盐中金属氧化物单元的脱氧，但是，使用双金属（Co-Cu）磷酸盐在30°C和40°C时可以消除。在30°C下计算出的反应速率常数为4.78 min ^-1，与其他报道的钴基催化剂相比，它具有非常高的优越性。这项研究为使用经济高效的过渡金属催化剂实现超快催化还原和消除有毒硝基苯酚提供了可能性。
