摘要
Provided are organosilica composites based on bis(3-triethoxysilylpropyl)tetrasulfide (TESPTS) or bis(3-triethoxysilylpropyl)disulfide (TESPDS) and containing octadecyltrimethoxy silane (C18TMS) and cetyltrimethylammonium bromide (CTAB), and a method for preparing hollow or porous carbon structures and silica structures using the same. According to the present disclosure, it is possible to obtain hollow or porous carbon structures and silica structures in a more simple and cost-efficient manner. Thus, the resultant structures have a high surface area and a large mesopore volume, so that they may serve as catalyst carriers for fuel cells capable of loading metal catalyst particles having a smaller particle size in a larger amount and in a more homogeneously dispersed state.
