The preparation of hydrogen by photocatalytic principle is an important
subject in the future energy direction. This article intends to design
the catalytic structure of a crystalline (amorphous)
TiO2/two-dimensional MoS2 sandwich structure supporting a single-atom,
and explore the effect of this special structure on the photocatalytic
reaction.Calculating the effective mass, electrostatic potential, light
absorption spectrum and other related properties by DFT method, the
analysis shows that the sandwich structure catalyst has good carrier
transfer ability and electron-hole separation ability. Except for the
Pt@Amorphousr-TiO2/MoS2 sandwich structure single-atom catalyst, which
only has an excellent effect on the oxygen evolution of water, the rest
of the interlayer catalysts have the two characteristics of
photocatalytic hydrogen evolution and oxygen evolution.The new catalyst
designed in this paper has innovative design ideas and high-efficiency
research and development value.
