Recyclable template synthesis of polymeric carbon nitride (CN) is rarely reported. Herein, for the first time, octamethyl polyhedral oligomeric silsesquioxane (mPOSS) was used as a recyclable soft template to prepare mesoporous CN with increased specific surface area, photoabsorption, charge separation efficiency, and photocatalytic H₂ evolution rate which is ∼4.5 times that of the bulk CN. mPOSS exhibits high stability and recoverability. This work opens an avenue for recyclable template synthesis of mesoporous CN and may advance its industrial application.

多面体低聚倍半硅氧烷作为可回收的软模板，用于合成介孔聚合物氮化碳，并增强光催化氢的释放

很少报道聚合氮化碳（CN）的可回收模板合成。本文首次以八甲基多面体低聚倍半硅氧烷（mPOSS）作为可回收的软模板，制备了介孔CN，其比表面积，光吸收率，电荷分离效率和光催化H ₂释放速率均是其的约4.5倍。大量CN。mPOSS具有很高的稳定性和可恢复性。这项工作为中孔CN的可回收模板合成开辟了一条途径，并可能促进其工业应用。
