Chiral mesoporous silica synthesized with the presence of different anionic acids

► In different inorganic acids reaction system, chiral mesoporous silica materials were achieved. ► The pore size at a range of 2.40-2.95 can be adjusted by changing the species of inorganic acids in reaction system. ► The pitch length and rod diameter maintained a linear relationship, as the acids changed from HCl, HBr and HNO3 to H2SO4.
