Summary:The present invention relates to a spherical mesoporous silica and a preparation method thereof. The present invention may: provide a spherical mesoporous silica characterized by funnel-shaped pores having large inlets; and increase the economic efficiency and a product yield by simplifying the preparation procedure of the spherical mesoporous silica. Further, since the spherical mesoporous silica has a large specific surface area and pore volume and thus has excellent adsorption capacity and can effectively release an adsorbed component for a long time after adsorption, the spherical mesoporous silica can be utilized as a carrier. La présente invention concerne une silice mésoporeuse sphérique et sa méthode de préparation. La présente invention peut : fournir une silice mésoporeuse sphérique caractérisée par des pores en forme d'entonnoir ayant de grandes entrées ; et augmenter l'efficacité économique et un rendement de produit en simplifiant la procédure de préparation de la silice mésoporeuse sphérique. En outre, étant donné que la silice mésoporeuse sphérique a une grande surface spécifique et un volume de pore élevé et ainsi a une excellente capacité d'adsorption et peut libérer efficacement un composant adsorbé pendant une longue durée après l'adsorption, la silice mésoporeuse sphérique peut être utilisée en tant que support. 본 발명은 구상형 메조 세공 실리카 및 이의 제조 방법에 관한 것으로, 입구가 큰 세공크기를 가지는 펀넬 구조의 특성을 가지는 구형 메조 세공 실리카를 제공할 수 있으며, 상기 구형 메조 세공 실리카의 제조공정을 단순화하여 경제성 및 제조 수율을 개선할 수 있다. 또한, 큰 비표면적 및 세공 부피로 인해, 흡착 성능이 우수하며, 흡착 후 장시간 흡착된 성분의 방출 효과를 나타낼 수 있어, 전달체로 활용 가능성이 큰 구상형 메조 세공 실리카 및 이의 제조 방법을 제공할 수 있다.
