The phenylthiourea-substituted triethoxysilane as a silane agent was synthesized and grafted on highly ordered nanoporous silica (LUS- 1) with a textured morphology and hexagonal array. This material (Tu-LUS-1) contained 0.8 mmol/g of soft base phenylthiourea group and surface area 760 m2 g-1 and was able to adsorb 0.75 mmolHg/g of TU-LUS-1 in endothermic reaction.
