摘要

本文利用密度泛函理论(DFT)研究了Cd+2离子在原始、C、P和C&P掺杂的bnnt内外表面的相互作用和吸附。计算结果表明,从热力学角度看,Cd+2的吸附是放热的。吸附Cd+2离子后,体系的电学和光学性质发生了明显的变化。量子、自然键轨道(NBO)和还原密度梯度(RDG)的检测结果证实了原始和掺杂的bnnt是生物和环境系统中Cd+2传感器和吸附剂的良好候选材料。

A Quantum, NBO, RDG study the interaction of cadmium ion with the pristine, C, P and C&P doped (4,4) armchair boron nitride nanotube (BNNTs)
In this paper, by using of density function theory (DFT), we have investigated the interaction and adsorption of Cd+2 ion on the interior and exterior surface of pristine, C, P and C&P doped BNNTs. The calculated results indicate that the adsorption of Cd+2 is exothermic in thermodynamic approach. With adsorbing Cd+2 ion the electrical and optical properties of system alter significantly from original state. Inspection of quantum, natural bond orbital (NBO) and reduced density gradient (RDG) results confirm that the pristine and doped BNNTs are a good candidate to making sensor and adsorbent of Cd+2 in biological and environmental system.
