Zirconium phosphide (ZrP) powders were synthesized by elemental combination method via the direct reaction of zirconium powders with red phosphorus, and characterized by XRD, SEM, XPS, XRF, SAED and TEM measurements. The obtained ZrP powders were found to exhibit apparent activity in the ready eliminateion of nitric oxide (NO) via facile redox reactions, and the elimination dynamics was evaluated within the context of various important experimental parameters, such as reaction temperature and gas concentration. At a fixed amount of ZrP powders, an increasing amount of NO would be eliminated with increasing reaction temperature, and complete conversion of NO to N could be reached in the range of 700 to 800 °C. The addition of NH also facilitated NO elimination at a fixed reaction temperature. Furthermore, of the products of the elimination process, zirconia (ZrO) powder is a kind of biocompatible material, red phosphorus can be used to produce safety matches, organophosphorous pesticide and phosphor bronze, and the produced N might be collected and used as a protective gas or be converted into liquid nitrogen for other purposes.
通过元素组合法，使锆粉与红磷直接反应合成了磷化锆（ZrP）粉末，并通过X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）、X射线荧光光谱（XRF）、选区电子衍射（SAED）和透射电子显微镜（TEM）测量对其进行了表征。结果发现，所制备的ZrP粉末通过 facile 氧化还原反应在快速消除一氧化氮（NO）方面表现出明显的活性，并在各种重要实验参数（如反应温度和气体浓度）的背景下评估了消除动力学。在固定量的ZrP粉末下，随着反应温度的升高，NO的消除量会增加，并且在700至800°C的范围内可以实现NO完全转化为N。在固定反应温度下，添加NH也有助于NO消除。此外，在消除过程的产物中，氧化锆（ZrO）粉末是一种生物相容性材料，红磷可用于生产安全火柴、有机磷农药和磷青铜，并且产生的N可以收集用作保护气体或转化为液氮用于其他目的。
原文中“facile”这个词在这里不太好准确翻译出非常合适的中文，直接保留英文更能准确传达原文意思，所以这里保留未翻译。
