Ultrasonic-assisted reactions, as a green technique, are often more efficient compared to those traditional protocols. To this end, the selective and solvent-free oxidation of aromatic alcohols to the corresponding aldehydes and ketones were investigated in the presence of Co-ABDC/W at room temperature under ultrasonic irradiation conditions for the first time in this paper. The structure, particle size, thermal stability, and morphology of the fabricated heterogeneous catalyst and the products were characterized by FT-IR, EDS, FE-SEM, XRD, TGA, and GC analyses. In this regard, immobilization of tungstate had a significant effect on thermal stability (around 450 °C for 40% weight loss) and catalytic performance. Moreover, the efficiency of two different oxidation methods, including ultrasound irradiations and reflux, were comparatively investigated by GC spectrometry. Obtained sonoxidation results presented higher conversions ranging (84 to 100%) than reflux condition via shorter reaction times. The influences of the reaction parameters, such as hydrogen peroxide concentration, and catalyst loading, were also investigated. The proposed method offers several advantages, such as excellent conversions, selective oxidations, environmentally-benign procedure, short reaction times, and easy workup. Notably, this is the first report that focuses on using amino-functionalized MOFs with ultrasonic irradiation for selective oxidation reactions.

与传统方法相比，作为绿色技术的超声辅助反应通常更有效。为此，本文首次在室温下在超声辐射条件下，在Co-ABDC / W的存在下，研究了芳香醇选择性和无溶剂氧化为相应的醛和酮。通过FT-IR，EDS，FE-SEM，XRD，TGA和GC分析表征了所制备多相催化剂及其产物的结构，粒度，热稳定性和形态。在这方面，钨酸盐的固定化对热稳定性（重量损失约40％的450℃左右）和催化性能有重大影响。而且，两种不同的氧化方法的效率，包括超声辐射和回流，通过气相色谱法进行了比较研究。通过较短的反应时间，获得的儿子氧化结果显示出比回流条件更高的转化率（84％至100％）。还研究了反应参数的影响，例如过氧化氢浓度和催化剂负载量。所提出的方法具有许多优点，例如优异的转化率，选择性氧化，对环境有益的程序，较短的反应时间以及易于后处理。值得注意的是，这是第一份针对使用氨基官能化MOF和超声辐射进行选择性氧化反应的报告。还研究了过氧化氢浓度和催化剂负载量。所提出的方法具有许多优点，例如优异的转化率，选择性氧化，对环境有益的程序，较短的反应时间以及易于后处理。值得注意的是，这是第一份针对使用氨基官能化MOF和超声辐射进行选择性氧化反应的报告。还研究了过氧化氢浓度和催化剂负载量。所提出的方法具有许多优点，例如优异的转化率，选择性氧化，对环境有益的程序，较短的反应时间以及易于后处理。值得注意的是，这是第一份针对使用氨基官能化MOF进行超声辐射进行选择性氧化反应的报告。
