Present work demonstrates a single step process for simultaneous synthesis of metal-nanoparticle-encapsulated nitrogen-doped bamboo-shaped carbon nanotubes (M/N-BCNTs) and graphitic carbon nitride (G-C3N3). The synthesis of two different carbon nanostructures in a single step is recognized for the first time. This process involves the use of inexpensive and nontoxic precursors such as melamine as carbon and nitrogen sources for the growth of G-C3N3 and M/N-BCNTs. In this technique, the utilization of unwanted gases such as ammonia and hydrocarbons released during the decomposition of melamine is the key to grow M/N-BCNTs over the catalyst along with the formation of G-C3N4. The implementation of M/N-BCNTs as the electrode material for all-solid-state symmetric supercapacitor results in a maximum specific capacitance of ∼368 F g–1 with excellent electrochemical stability with 97% capacity retention after 10 000 cycles. Furthermore, fabricated symmetric supercapacitor shows maximum high energy and power density up to 10.88 W h kg–1 and 2.06 kW kg–1, respectively. The superior electrochemical activity of M/N-BCNTs can be attributed to its high surface to area volume ratio, unique structural characteristics, ultrahigh electrical conductivity, and carrier mobility.

全固态对称超级电容器的两种含氮碳纳米材料的化学同时合成策略
本工作展示了同时合成金属纳米颗粒包裹的氮掺杂竹形碳纳米管（M / N-BCNT）和石墨氮化碳（GC 3 N 3）的一步法。首次认识到在一个步骤中合成两种不同的碳纳米结构。此过程涉及使用廉价且无毒的前体（例如三聚氰胺）作为碳源和氮源，以生长GC 3 N 3和M / N-BCNT。在此技术中，利用三聚氰胺分解过程中释放的有害气体（例如氨和碳氢化合物）是在催化剂上生长M / N-BCNT以及形成GC 3 N 4的关键。。将M / N-BCNTs用作全固态对称超级电容器的电极材料可产生约368 F g –1的最大比电容，具有出色的电化学稳定性，在1万次循环后可保持97％的容量。此外，制造的对称超级电容器显示出分别高达10.88 W h kg –1和2.06 kW kg –1的最大高能量和功率密度。M / N-BCNT的优异电化学活性可以归因于其高的表面积与体积之比，独特的结构特征，超高的电导率和载流子迁移率。
