Selective hydrodeoxygenation (HDO) of guaiacol is a green and sustainable method to produce cyclohexanol. However, developing an economically efficient and highly selective non-precious metal catalyst for the HDO reaction remains a significant challenge. Here, we synthesized rod-like CoNi alloy catalysts via calcination a precursor of CoNi-BTC metal–organic framework (MOF). And a selectivity up to 94.9% can be achieved for cyclohexanol under mild reaction conditions. According to the analysis of characterization, the specific surface area and pore size had a dual impact on the catalyst activity calcinated at different temperatures. The synergistic effect of the CoNi alloy also led to an enhanced hydrogen adsorption capability of the catalyst, resulting in a significant enhancement in catalytic activity compared to the monometallic catalyst. This article provides a reference for the rational design of alloy MOF materials for catalyzing high-performance HDO of guaiacol.

愈创木酚选择性加氢脱氧（HDO）是一种绿色、可持续的环己醇生产方法。然而，开发一种经济高效且高选择性的 HDO 反应非贵金属催化剂仍然是一个重大挑战。在这里，我们通过煅烧 CoNi-BTC 金属有机骨架（MOF）的前体合成了棒状 CoNi 合金催化剂。在温和的反应条件下，环己醇的选择性高达94.9%。表征分析表明，比表面积和孔径对不同温度焙烧的催化剂活性有双重影响。CoNi合金的协同效应还导致催化剂的氢吸附能力增强，与单金属催化剂相比，催化活性显着增强。
