Beneficial metal ion insertion into dandelion-like MnS with enhanced catalytic performance and genetic morphology

Abstract

Large-scale novel hierarchical dandelion-like MnS was successfully synthesized with manganese complex as a template under mild reaction conditions. A mixture of ethylenediamine and ethylene glycol was used as a solvent. Large-scale manganese complexes were obtained via a one-step reaction; the synthesis was very simple, and the raw materials were inexpensive. The as-prepared MnS was used as a template. The introduction of beneficial metals facilitated the catalytic performance of the as-obtained multiple sulphides. Meanwhile, the genetic morphology between the as-prepared MnS and the multiple sulphides was realized via cation exchange. The composition of the products could be adjusted through cation exchange at room temperature; meanwhile, the performance of the products was improved by a large margin without changing the morphology. The as-prepared products showed highly efficient catalytic properties in degrading dye-containing solutions, such as methylene blue and rhodamine B. This result indicated that the performance of the products could be improved by introducing beneficial metals without changing the morphology.
