The large‐sized nanofilm‐constructed hierarchical porous SiO2 (LNCHPS) is successfully prepared by the dual templating approach and subsequently used as the support for g‐C3N4. A series of characterization techniques are conducted to evaluate the structure and property of the as‐prepared materials. The LNCHPS possesses two sets of explicated successive pass‐through macropores (0.5–1.0 µm) with large specific surface area. In addition, the macropore wall is constructed by uniform mesoporous nanofilms with the thickness ranging from 35 to 50 nm. Then, the photocatalytic property is investigated by degradations towards Rhodamine B (RhB) under simulated sunlight, in which experiments have been performed through controlling the g‐C3N4 loading contents, solution pH values, and photocatalyst dosages. The apparent rate constant of g‐C3N4/LNCHPS could reach 0.03 min−1 under optimum conditions, showing 6.0 times that of the bulk g‐C3N4. In addition, g‐C3N4/LNCHPS also exhibits significantly enhanced performance in H2 evolution (39.9 µmol h−1) compared to that of the bulk g‐C3N4. High light absorption and utilization, enhanced adsorption capability and quick electron hole separation can render this fine structure excellent photocatalytic performance. Our work enables a facile route for large‐scale preparation of g‐C3N4/LNCHPS for addressing the wastewater treatment and hydrogen energy production simultaneously.

“…MEMP was synthesized according to Ref. [45], and then used as the macroscopic shape and macropore template. The titanosilicate precursor solution was prepared by mixing 30 mL deionized water, 20 mL TPAOH (25 wt.%), 1.0 g TiPr and 25 mL TEOS under stirring at 40 °C for 3 h, followed by aging at 120 °C for 3 h in a PTFE lined hydrothermal autoclave.…”

Developing easily recyclable noble metal nanoparticle-based heterogeneous catalysts is highly desirable for the practical applications. Herein, a millimeter-sized hierarchical porous titanosilicate (HPTS) was prepared by the multi-template method. Various characterization results reveal that HPTS combines the structural advantages of monolith materials and nanomaterials. HPTS is used as an advanced support to construct the Ag/HPTS catalysts via the Ag + in situ reduction on its pore wall. Ag/HPTS shows high catalytic activity for 4-nitrophenol (4-NP) reduction with the TOF values of 3.91 min À 1 , which can be attributed to the ultrafine Ag NPs (2.04 nm) and the unique structure of HPTS. The 3D pass-through macroporous channels facilitate mass transfer. The mesopores with ultra-short channel remarkably enhance the accessibility of the active sites. The abundant mesopores and micropores effectively confine the Ag NPs size. Moreover, Ag/HPTS demonstrated good stability and recyclability.
