The novel mesoporous materials containing titanium and manganese, Ti-HMS (50) and Mn-HMS (50) (the number 50 denoting the Si/metal of molar ratio), were synthesized using laurylamine as template at room temperature. They were characterized by a series of techniques including powder XRD, FT-IR, UV–Vis spectroscopy, TEM, TG and Nitrogen physisorption. The results indicated that titanium and manganese...
Titanium silicate molecular sieves TS‐1 have been prepared under hydrothermal conditions with tetrapropylammonium hydroxide as structure‐directing agent. The structures of TS‐1 were characterized by means of XRD, TEM, FT‐IR, DR UV‐Vis, ICP‐AES, and N2 adsorption/desorption techniques. Its catalytic performances in the epoxidation of butadiene with hydrogen peroxide were investigated; 3,4‐epoxy‐1‐butene...
