摘要：
Limited by low surface area and insufficient photoelectric conversion efficiency, bulk g-C3N4 showed unsatisfactory photocatalytic pollutant degradation and H2 evolution performance. Herein, hydrophilic and porous HBeta zeolite was employed to prepare g-C3N4/H-Beta composite via facile in-situ polymerization method. The role of H-Beta zeolite manifested in increased surface area, improved hydrophilicity and facilitated separation and transportation of photoexcited charge carriers. Hence, the obtained g-C3N4/H-Beta photocatalyst with an optimal content of H-Beta zeolite showed highest photocatalytic pollutant degradation efficiency and H2 generation rate, which were 7.31- and 6.32-fold greater than that of bulk g-C3N4.
