Abstract: Disclosed herein is a method for the preparation of porous materials, which can be used not only for a catalyst, an adsorbent, a catalytic support, ion exchange and gas storage, but also for adsorbent of guest molecules due to nanometer spaces (nanospaces), and of mixed metal oxides which are used as functional ceramic materials. More particularly, disclosed is a method for the preparation of porous materials and mixed metal oxides, in which microwave energy is used as a heating source, and a tube free of connection portions is used as a reactor, and the pressure within the reactor is controlled by measuring the pressure of gas remaining after the separation of solid and liquid, so that the method has increased operational stability and reproducibility, makes the control of residence time easy, and can achieve an increase in productivity. Also, disclosed is an apparatus for the continuous preparation of porous materials and mixed metal oxides, which can perform the preparation method.

Abstract: The present invention relates to a catalyst for preparing hydrocarbons of carbon dioxide and more particularly, the Fe—Cu—K/?—Al2O3 catalyst prepared by impregnation which enables producing hydrocarbons in high yield for more than 2000 hours due to its excellent activity and stability.

Abstract: The present invention relates to a novel titania photocatalyst and its manufacturing method. More specifically, the present invention is to provide the quantum-sized novel titania photocatalyst prepared the steps comprising: (a) titanium tetraisopropoxide is encapsulated in zeolite support by adding citric acid to isopropyl alcohol; (b) ethylene glycol is dissolved herein to obtain a uniformly dispersed mixture solution; and (c) it is encapsulated in zeolite cavities.
