Here in we report a facile method of self-phosphorous doped porous carbon by a simple carbonization route (without using any activation process) under argon gas atmosphere. The as-prepared material with high surface area of 756 m² g⁻¹ shown high H₂ storage capacity of ∼1.75 wt% at 298 K and 100 bars. Also, it exhibited a high specific capacitance of 253 Fg⁻¹ at the current density of 1 A g⁻¹. Further, it also showed the capacitive retention of ∼95% at the current density of 5 A g⁻¹ for 10,000 cycles. Interestingly, a carbon material with porous structure is predominantly inspiring as they are cost-effective and ease to synthesis for industrial applications. Biomass derived self-phosphorous doped porous carbon is considered as a superior material for supercapacitor and hydrogen storage applications. It is shown high performance for both the applications, due to its exceptional chemical stability, conductivity, micro-meso porosity, high specific surface area, cost-effectiveness and sustainability.

在这里我们报告了一种在氩气气氛下通过简单的碳化途径（不使用任何活化过程）的自磷掺杂多孔碳的简便方法。所制得的具有高表面积756 m ² g ^-1的材料在298 K和100巴下显示出约1.75 wt％的H ₂高存储容量。此外，在1 A g ^-1的电流密度下，它具有253 Fg ^-1的高比电容。此外，在电流密度为5 A g ^-1时，电容保持率约为95％10,000个周期。有趣的是，具有多孔结构的碳材料是最受启发的，因为它们具有成本效益，并且易于工业应用合成。生物质衍生的自磷掺杂多孔碳被认为是超级电容器和储氢应用的上乘材料。由于其出色的化学稳定性，电导率，微介孔率，高比表面积，成本效益和可持续性，在两种应用中均显示出高性能。
