The Palladium (Pd) nanoparticles were immobilized on the boron (B), nitrogen (N) doped porous carbon (BNC-50) through replacing cobalt path at room temperature, which was derived from the high-temperature pyrolysis of the modified Zeolitic Imidazolate Frameworks (ZIF) composes coated with 5-boronoisophthalic acid. The Pd nanoparticles could be uniformly dispersed on the BNC-50 supports by replacement reaction to effectively avoid the Pd nanoparticles agglomeration. Meanwhile, the B, N doping can further grapple the palladium nanoparticles with luxuriant activity sites during the loading process. The highly order carbon frameworks also offer more porous paths and interspace to enhance the mass and charge delivery. Therefore, the synthetic catalysis of palladium nanoparticles immobilized on the porous B, N-doped carbon displays excellent activity (Pd/BNC-50) for ethanol oxidation reaction (EOR). The catalytic activities of the Pd/BNC-50 with peak current density (2638.41 mA mg⁻¹) are 3.77 times than that of Pd/C in the basic reaction solution.

钯（Pd）纳米颗粒通过在室温下替换钴路径而固定在硼（B），氮（N）掺杂的多孔碳（BNC-50）上，这是由改性沸石咪唑盐骨架的高温热解得到的（ZIF）组成涂有5-硼氢化间苯二甲酸。Pd纳米粒子可以通过置换反应均匀地分散在BNC-50载体上，从而有效避免Pd纳米粒子的团聚。同时，B，N掺杂可在负载过程中进一步使钯纳米颗粒具有茂盛的活性位。高度有序的碳骨架还提供了更多的多孔路径和间隙，以增强质量和电荷的输送。因此，固定在多孔B上的钯纳米粒子的合成催化 氮掺杂碳对乙醇氧化反应（EOR）表现出优异的活性（Pd / BNC-50）。Pd / BNC-50的峰值电流密度（2638.41 mA mg^-1）是碱性反应溶液中Pd / C的3.77倍。
