摘要： Provided is a calcium-based catalyst and a method for catalytically synthesizing an alkanolamide surfactant thereof. The method includes the preparation of the catalyst, and then catalyzing a reaction of fat and oil, or fatty acid ester and alkanolamine with the catalyst to synthesize a light colored alkanolamide surfactant with less free alkanolamine. The catalyst has a slow release feature, so that late in the reaction, the catalyst still has relatively high catalytic reactivity, guaranteeing a high conversion rate of the alkanolamine into the alkanolamide surfactant, the, product residual quantity of alkanolamine is low, while the risk of nitrosamine production due to product residual alkanolamine is greatly lowered. Due to catalyst slow release control, the early reaction period speed is greatly reduced, thereby avoiding a deepened product color caused by poor heat transfer due to an early reaction period being excessively fast.

摘要： Provided are a silicate modified manganese-based material and a preparation method and application thereof. The silicate modified manganese-based material has a nanoscale needle like structure, and is prepared from a solution containing a manganese source and a soluble silicate source through an oxidation-reduction reaction and then a hydrothermal reaction. The manganese source includes a divalent manganese source and a heptavalent manganese source, with Mn (II) and Mn (VII) in a molar ratio of 0.5-5.5 to 1. The present disclosure uses silicate to regulate manganese oxides, significantly reducing the particle size of the manganese-based material, generating manganese vacancies, and changing the surface manganese valence state. An advanced oxidation system formed by the silicate modified manganese-based material and an oxidant has high removal rate and reaction rate for various organic compounds.

摘要： A hollow mesoporous organic silica nano/microparticle having metal particles deposited thereon, and a method for preparing the same. The method may prepare a spherical nanoparticle by coating a porous organic silica layer on an inorganic silica particle having the metal particles deposited thereon and via selective etching of the layer. In addition, two or more types of metals pre-synthesized together with a magnetic particle, or different shapes of metals may be deposited on the nanoparticle at a target concentration. Thus, the nano/microparticle may be used for a drug delivery matrix, a catalyst, and a photothermal effect.
