• Mesoporous graphitic C3N4 was prepared via a hard templating route.
• A novel cross-linked bimodal mesoporous SBA-15 is used as a hard template.
• Numerous mesopore openings are formed on the surfaces of mesoporous g-C3N4.
• Mesoporous g-C3N4 shows a high specific surface area and a large pore volume.
• Mesoporous g-C3N4 exhibits the high photocatalytic performance with visible light.
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.
