摘要：
The hyperbolic geometry of the pores in SBA-15 are drawn into a three-dimensional structure by small lateral pores, distributed in a random way, as shown in the picture, which interconnect the main channels. This construction was established by forming a "negative" of the structure with platinum precipitated in the channel and dissolving the SBA-15 material.
