以磷化锆（ZrP）和氧化石墨烯（GO）为原料，采用水热法制备了磷化锆/石墨烯复合材料（ZrP@rGO），并通过XRD、SEM、N2吸附-脱附和TEM等手段对其进行了表征。所得到的ZrP@rGO复合材料被发现表现出明显的活性，在消除一氧化氮（NO）通过简单的氧化还原反应，消除动力学的各种重要的实验参数，如反应温度和氨气浓度的范围内进行了评估。在ZrP@rGO复合物的固定量下，随着反应温度的升高，将消除增加量的NO，并且在650至800 °C的范围内可以达到NO向N2的完全转化。NH3的加入也促进了在固定反应温度下NO的消除。此外，作为消除反应的产物，氧化锆（ZrO 2）粉末是生物相容性材料，赤磷可用作化学材料，并且N2可被收集并用作保护气体或其他目的。
The composites of zirconium phosphide with graphene (ZrP@rGO) were synthesized via a hydrothermal process with zirconium phosphide (ZrP) and graphene oxide (GO) as raw materials, and characterized by XRD, SEM, N2–adsorption–desorption and TEM measurements. The obtained ZrP@rGO composites were found to exhibit apparent activity in the elimination 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 ammonia gas concentration. At a fixed amount of ZrP@rGO composites, an increasing amount of NO would be eliminated with increasing reaction temperature, and complete conversion of NO to N2 could be reached in the range of 650 to 800 °C. The addition of NH3 also facilitated NO elimination at a fixed reaction temperature. Furthermore, as of the products of the elimination reaction, zirconia (ZrO2) powders are biocompatible material, red phosphorus can be used as chemical material, and the N2 might be collected and used as a protective gas or other purposes.
