Ni-based supported catalyst was prepared by supercritical carbon dioxide deposition method using NiCl2 as precursor and carbon nanotubes (CNT) as carrier, and characterized by XRD, Raman, SEM, TEM, EDS and BET for its crystal structure, microstructure and pore structure. The effects of reaction temperature (55~75 ℃) and pressure (9~18 MPa) on the Ni loading (the mass fraction of Ni measured by ICP, the same below) of S-Ni-CNT were evaluated. The S-Ni-CNT was further used as cathode of Li-CO2 battery, followed by analysis on the electrochemical performance of the battery. The results showed that the S-Ni-CNT had a Ni loading of 3.61% under the optimal synthesis conditions of temperature 65 ℃ and pressure 18 MPa, showing excellent single-atom dispersion, with a specific surface area of 220.14 m2/g, which was only reduced by 13.6% compared with that of the CNT carrier (254.74 m2/g). The mesoporous structure of S-Ni-CNT accounted for 90%. At a current density of 100 mA/g, the discharge specific capacity of S-Ni-CNT battery could reach 16427 mA·h/g, at a current density of 300 mA/g, the discharge voltage platform was 2.67 V and the charge voltage platform was 3.85 V. At a density current of 500 mA/g, after the battery undergone 100 charge-discharge cycles, the voltage retention rate was 94%.

以NiCl2为前驱体、碳纳米管(CNT)为载体,采用超临界二氧化碳沉积法制备了负载型Ni基超临界-镍-碳纳米管复合催化剂(S-Ni-CNT)。采用XRD、Raman、SEM、TEM、EDS、BET对其晶体结构、微观形貌、孔结构进行了表征。考察了反应温度(55~75 ℃)、反应压力(9~18 MPa)对S-Ni-CNT的Ni负载量(ICP测得Ni的质量分数,下同)的影响。将S-Ni-CNT用作Li-CO2电池正极,评价了电池的电化学性能。结果表明,在反应温度65 ℃、反应压力18 MPa的最佳工艺条件下,S-Ni-CNT的Ni负载量最高,为3.61%,呈现出优异的Ni金属单原子分散性,其比表面积达220.14 m2/g,相较于载体CNT的254.74 m2/g,仅降低13.6%,S-Ni-CNT介孔结构占比90%。在100 mA/g电流密度下,S-Ni-CNT电池的放电比容量可达16427 mA·h/g;在300 mA/g电流密度下,S-Ni-CNT电池的放电电压平台为2.67 V,充电电压平台为3.85 V;在500 mA/g电流密度下,S-Ni-CNT电池经过100次循环后,电压保持率为94%。

以NiCl2为前驱体、碳纳米管(CNT)为载体,采用超临界二氧化碳沉积法制备了负载型Ni基超临界-镍-碳纳米管复合催化剂(S-Ni-CNT)。采用XRD、Raman、SEM、TEM、EDS、BET对其晶体结构、微观形貌、孔结构进行了表征。考察了反应温度(55~75 ℃)、反应压力(9~18 MPa)对S-Ni-CNT的Ni负载量(ICP测得Ni的质量分数,下同)的影响。将S-Ni-CNT用作Li-CO2电池正极,评价了电池的电化学性能。结果表明,在反应温度65 ℃、反应压力18 MPa的最佳工艺条件下,S-Ni-CNT的Ni负载量最高,为3.61%,呈现出优异的Ni金属单原子分散性,其比表面积达220.14 m2/g,相较于载体CNT的254.74 m2/g,仅降低13.6%,S-Ni-CNT介孔结构占比90%。在100 mA/g电流密度下,S-Ni-CNT电池的放电比容量可达16427 mA·h/g;在300 mA/g电流密度下,S-Ni-CNT电池的放电电压平台为2.67 V,充电电压平台为3.85 V;在500 mA/g电流密度下,S-Ni-CNT电池经过100次循环后,电压保持率为94%。

Ni-based supported catalyst was prepared by supercritical carbon dioxide deposition method using NiCl2 as precursor and carbon nanotubes (CNT) as carrier, and characterized by XRD, Raman, SEM, TEM, EDS and BET for its crystal structure, microstructure and pore structure. The effects of reaction temperature (55~75 ℃) and pressure (9~18 MPa) on the Ni loading (the mass fraction of Ni measured by ICP, the same below) of S-Ni-CNT were evaluated. The S-Ni-CNT was further used as cathode of Li-CO2 battery, followed by analysis on the electrochemical performance of the battery. The results showed that the S-Ni-CNT had a Ni loading of 3.61% under the optimal synthesis conditions of temperature 65 ℃ and pressure 18 MPa, showing excellent single-atom dispersion, with a specific surface area of 220.14 m2/g, which was only reduced by 13.6% compared with that of the CNT carrier (254.74 m2/g). The mesoporous structure of S-Ni-CNT accounted for 90%. At a current density of 100 mA/g, the discharge specific capacity of S-Ni-CNT battery could reach 16427 mA·h/g, at a current density of 300 mA/g, the discharge voltage platform was 2.67 V and the charge voltage platform was 3.85 V. At a density current of 500 mA/g, after the battery undergone 100 charge-discharge cycles, the voltage retention rate was 94%.
