摘要：

Mesoporous graphitic C3N4 has been synthesized using a novel cross-linked bimodal mesoporous (CLBM) SBA-15 as a hard template. This cross-linked bimodal mesoporous SBA-15 template was prepared by adjusting the pH to alter the copolymer micelle size. The resulting mesoporous g-C3N4 replicates the morphology of the mesoporous silica template, and numerous pore openings are formed on the surfaces. The mesoporous g-C3N4 exhibits a high specific surface area and a large pore volume. The photocatalytic degradation activity of methyl orange on mesoporous g-C3N4 is nearly 15.3 times as high as that on bulk-g-C3N4 under visible light irradiation. The high photocatalytic performance of this sample is due to the high specific surface area and more readily accessible active sites. (C) 2015 Elsevier Inc. All rights reserved.
