摘　　要：通过静电纺丝和退火工艺设计并合成了SnS_(0.5)Se_(0.5)纳米粒子偶联N/S/Se三掺杂碳纳米纤维复合材料(SnS_(0.5)Se_(0.5)@NSSe-C).SnS_(0.5)Se_(0.5)和NSSe-C的协同效应使得SnS_(0.5)Se_(0.5)@NSSe-C纳米纤维在高电流密度下具有高可逆容量和超长循环寿命.此外,理论计算进一步表明SnS_(0.5)Se_(0.5)@NSSe-C复合材料具有较高的Na+吸附能,能够表现出更加优异的离子传输性能.本研究为三元锡基硫族化合物的合成提供了新的思路,并有助于研究其反应动力学.In this paper,SnS_(0.5)Se_(0.5)nanoparticles coupled with N/S/Se triple-doped carbon nanofibers(SnS_(0.5)Se_(0.5)@NSSe-C)are designed and synthesized through electrospinning and annealing process.Benefiting from the synergistic effects of SnS_(0.5)Se_(0.5)and NSSe-C,the SnS_(0.5)Se_(0.5)@NSSe-C nanofibers exhibit a high reversible capacity and ultralong cycle life at higher current density for sodium-ion batteries.Furthermore,the theoretical calculations reveal the structural advantages of SnS_(0.5)Se_(0.5)@NSSe-C composite,which exhibits a high adsorption energy of Na+.This work can provide a novel idea for the synthesis of ternary tin-based chalcogenides and is beneficial for the investigation of their reaction kinetics.
