A sustainable and easy method for the fabrication of a composite of ultra-fine few-layer MoS₂ structures embedded on N,P-co-doped bio-carbon (MoS₂-N/P-C) was developed by using natural chlorella as an adsorbent and reactor. This MoS₂-N/P-C composite was easily synthesized by carrying out a biosorption of chlorella and a subsequent calcination process. This bio-carbon made from chlorella acted as a nanoreactor to prevent the MoS₂ nanoparticles from agglomerating with each other during the calcination process. Besides, the N,P-codoped bio-carbon contributed to the relatively high conductivity and surface wettability of this composite and accommodated the large radius of Na⁺. When used as an anode for sodium ion batteries, it showed significant superiority with a high rate and long-duration cycling performance, evidenced by a measured capacity of 175 mA h g⁻¹ after 2000 cycles at 5 A g⁻¹.

嵌入N，P共掺杂生物碳上的超细多层MoS2超细复合材料，用于高性能钠离子电池

以天然小球藻为吸附剂，开发了一种可持续，简便的方法，制备了嵌入N，P共掺杂生物碳（MoS ₂ -N / PC）上的超细多层MoS ₂超细结构复合材料。和反应堆。通过进行小球藻的生物吸附和随后的煅烧过程，可以容易地合成这种MoS ₂ -N / PC复合材料。这种由小球藻制成的生物碳可充当纳米反应器，以防止MoS ₂纳米粒子在煅烧过程中彼此凝聚。此外，N，P掺杂的生物碳有助于该复合材料具有较高的电导率和表面润湿性，并具有较大的Na ⁺半径。当用作钠离子电池的阳极时，它在高速率和长周期的循环性能方面显示出显着的优越性，这在5 A g ^-1下经过2000次循环后测得的容量为175 mA hg ^-1即可证明。
