Two-Dimensional Carbon Film-Supported ZnS Nanocomposites Obtained from Thermal Decomposition of Organic Zinc Salts and Sulfidation Reactions for Lithium Storage.

ABSTRACT: This article reports a general method for carbon-composited ZnS nanoparticles. By mixing thiourea with an appropriate amount of citric acid zinc, glycine zinc, lactate zinc, and gluconate zinc, respectively, and then heating at 700 °C under a nitrogen atmosphere for 4 h, four types of target product ZnS/C were obtained. Thiourea and organic zinc salts serve as reactants, providing zinc, sulfur, and carbon sources. During the thermal decomposition process, sulfidation and carbonization can be completed simultaneously. As an anode material for lithium-ion batteries, all four products exhibit excellent lithium storage performance. The two-dimensional carbon film can, on the one hand, enhance the conductivity of the material, and on the other hand, act as a carrier for ZnS particles, effective
