The catalytic activity of CeO₂ and palladium nanoparticles supported fly ash zeolite (CeO₂/Pd@FAZ) for C_sp²‐C_sp² bond formation was studied. CeO₂/Pd@FAZ was characterized by FTIR, XRD, EDAX and TEM studies. In the Suzuki‐Miyauracross‐coupling reaction, biphenyl derivatives with excellent yields were obtained, and the reaction conditions were optimized. The catalytic activity was explored using a wide variety of diversely substituted aryl bromides and chlorides with aryl boronic acid under optimized reaction conditions. The recyclability of the catalyst was established for three cycles, with the conversion rate from 99 to 40%, which gained the advantage of heterogeneous catalysis.

CeO2 / Pd纳米颗粒掺入粉煤灰沸石：Csp2-Csp2键形成反应的高效可回收催化剂

研究了CeO ₂和钯纳米粒子负载粉煤灰沸石（CeO ₂ / Pd @ FAZ）对C _sp² -C _sp²键形成的催化活性。通过FTIR，XRD，EDAX和TEM研究对CeO ₂ / Pd @ FAZ进行了表征。在Suzuki-Miyauracross偶联反应中，获得了具有优异收率的联苯衍生物，并优化了反应条件。在优化的反应条件下，使用各种不同取代的芳基溴化物和氯化物与芳基硼酸一起探索催化活性。建立了三个循环的催化剂可回收性，转化率从99％降至40％，从而获得了多相催化的优势。
