| Abstract: | A simple in situ hydrothermal process with a single step, a mesoporous g-C3N4/Co-Al LDH composite photocatalysts were produced. Co-Al LDH (CAL) and g-C3N4 (CN) nanocrystals were able to effectively build a laminated van der Waals heterostructure as a result of the strong electrostatic connections amid the two materials. The generated samples were examined for their optical, structural, and morphological features by using UV, XRD, PL and TEM analysis. The impressive hydrogen evolution rate of 3677.5 μmmolh−1 g−1 was shown by the as-prepared 15 mol% CN/CAL, which was 7.5 times more than that of pure CAL (490.5 μmmolh−1 g−1). Since of its rare structure and active surface area, it may have a higher activity level. To reduce the charge transmission distance, a 2D heterojunctions outperform traditional heterojunction photocatalysts in preventing the recombination of charge carriers caused by light. These heterojunctions include several 2D coupling designs and high levels of interfacial contact. [ABSTRACT FROM AUTHOR] |
