Fabrication of flower-like Sn3O4 hierarchical nanostructure and its photocatalytic activity for H2 evolution from water

Morphology-Governed Performance of Multi-Dimensional Photocatalysts for Hydrogen Generation

“…Finally, a flower-like nanostructure has also been tested for hydrogen evolution under vis (λ > 420 nm) irradiation. The Sn 3 O 4 has been prepared in the form of a flower by a hydrothermal method without templates or surfactants [138]. It has been found that a platinized flower-like nanostructure is much more efficient (85%) than platinized sheets, reaching 184 µmol•h −1 •g −1 hydrogen evolution (CH 3 OH as a sacrificial reagent).…”

Rational design of 0D/3D Sn3O4/NiS nanocomposites for enhanced photocatalytic hydrogen generation

“…Sun and co-workers prepared the Sn 3 O 4 flower-like structure by a one-step method without a template, which dramatically increased the hydrogen production capability of the system after adding the noble metal co-catalyst Pt. 38 However, it is worth noting that the majority of co-catalyst modifications for Sn 3 O 4 are based on noble metals such as Pt, which are prohibitively expensive and prevent the catalyst from being widely used. As a result, it is still critical and highly desired to develop innovative, economical and efficient noble-metal-free co-catalysts to expedite the carrier separation and transfer and increase the H 2 generation efficiency of Sn 3 O 4 .…”
