Abstract:
A versatile eco-friendly planting block includes: a block body in a form of a hexahedron; cut-off grooves formed at vertex parts of each surface of the block body in symmetrical to each other about a diagonal line of each surface of the block body; and a planting groove selectively formed in the cut-off groove so that vegetation is planted.
Abstract:
The present invention relates to a mesoporous silica/ceria-silica composite and a method for preparing a mesoporous composite and, more specifically, to a mesoporous silica/ceria-silica composite which is composed of mesoporous silica having a hexagonal or cubic structure and ceria having a hexagonal structure provided on a surface and pores of the mesoporous silica, the oxidation state of the ceria being Ce4+ and Ce3+.
