Fast synthesis of uniform mesoporous silica spheres

Fast synthesis of materials is vital for the industrial mass production in consideration of high efficiency and low cost. Here, we have originally developed a simple, feasible and scalable method realizing fast synthesis of uniform mesoporous silica (SiO2) spheres (UMSSs) via one-step hydrothermal treatment with only 2 h reaction time. The UMSSs have high surface area, large pore volume and abundant pores with short-range order, and exhibit impressive antibacterial activity.
