Photocatalytic hydrogen production could sustainably and efficiently convert solar energy. However, a low light utilization ratio limits the wide application. Herein, Moiré-like structure was constructed in TiO2 body to improve absorption by multiple reflections suitable dispersion diffraction based on similar wavelength nick. Furthermore, slightly reduces band gap accelerates separation of photogenerated electrons holes, mass transfer enhanced regular nano-channels Bernoulli phenomenon. After calcination at 500 °C (M-T500), compared with pure TiO2, M-T500 achieved 20% increase RhB degradation efficiency double rate, thus providing novel design for catalysts high catalytic strategy. Moreover, nearly 100% recovery rate supported environmental protection sustainable development.

A series of catalysts were synthesized via a combination evaporation-induced self-assembly and spray pyrolysis; they then applied to the direct decomposition methane. Among them, Ni-Cu/MgO exhibited smallest Ni particle size (~9 nm), attributed Cu-induced suppression crystal growth during synthesis. These achieved highest carbon yield, primarily due enhanced dispersion nanoscale particles. The interaction between methane catalysts, as well structural electrical properties resulting nanotubes, such crystallinity conductivity, investigated with respect support material (MgO vs. Al2O3) metal composition (Ni Ni-Cu). findings provide valuable insights for designing advanced catalyst systems efficient conversion into high-value carbon-based materials.
