Abstract

Flowerlike WSe₂ and WS₂ microspheres were synthesized by a facile and scalable one-pot solvothermal method. Their formation mechanism followed the reaction between dissolved W(CO)₆ and dissolved S or melted Se without complete decomposition of W(CO)₆ into tungsten. As novel efficient sorbents, WSe₂ and WS₂ demonstrated outstanding uptake capacities for Pb²⁺ and Hg²⁺.
