摘要：

In　phosphoric　acid　medium,　highly　ordered　mesoporous　sieve　SBA-15　was　prepared　through　hydrothermal　method.　By　means　of　XRD,　N2　adsorption-desorption,　SEM,　the　properties　of　the　samples　were　characterized.　The　results　indicated　that　the　obtained　samples　possessed　2D　hexagonal　array　mesoporous　structure　with　high　degree　of　crystallization.　The　N2　adsorption-desorption　isotherms　showed　that　the　samples　had　narrow　pore　size　distribution,　the　BET　specific　surface　area　reached　937　m2/g,　pore　volume　reached　1.15　cm3/g,　and　the　mean　pore　size　was　around　6.49　nm.
