Abstract The present work was demonstrated to develop a solvent-free scrubber like zinc oxide-decorated multi-wall carbon nanotubes (ZnO-MWCNTs) to capture H2S at the ambient atmospheric condition in a laboratory scrubber set up. The resultant zinc sulfide-decorated multi-wall carbon nanotubes (ZnS-MWCNTs) is characterized by analytical techniques indicating facile conversion of ZnO to ZnS on the surface of MWCNTs. Surprisingly, synergistic effect of ZnO and MWCNTs indicates high H2S adsorption capacity of ZnO-MWCNTs at ambient temperature. Further, desulfurization performance in a realistic condition was employed using a bench-scale fixed bed reactor and seen that the ZnO-MWCNTs material showed the highest value of H2S removal (98%). Most importantly, regeneration process was developed for necessitates conversion of ZnS to ZnO by chemical method.

ZnO 装饰的多壁碳纳米管作为无溶剂纳米洗涤器，可有效去除 H2S

摘要 目前的工作证明了开发无溶剂洗涤器，如氧化锌装饰的多壁碳纳米管 (ZnO-MWCNTs)，以在实验室洗涤器装置中在环境大气条件下捕获 H2S。所得硫化锌装饰的多壁碳纳米管 (ZnS-MWCNT) 的特征在于分析技术表明 MWCNT 表面上 ZnO 易于转化为 ZnS。令人惊讶的是，ZnO 和 MWCNTs 的协同效应表明 ZnO-MWCNTs 在环境温度下具有高 H2S 吸附能力。此外，使用台式固定床反应器在实际条件下使用脱硫性能，发现 ZnO-MWCNTs 材料显示出最高的 H2S 去除值（98%）。最重要的是，再生过程的开发需要通过化学方法将 ZnS 转化为 ZnO。
