Zinc Oxide-Containing Porous Boron–Carbon–Nitrogen Sheets from Glycine–Nitrate Combustion: Synthesis, Self-Cleaning, and Sunlight-Driven Photocatalytic Activity
We developed a single-step thermal
method that enables successful inclusion of ZnO components in the
porous boron–carbon–nitrogen (BCN) framework to form
a new class of functional hybrid. ZnO-containing BCN hybrids were
prepared by treating a mixture of B<sub>2</sub>O<sub>3</sub>, glycine,
and zinc nitrate at 500 °C. Glycine–nitrate decomposition
along with B<sub>2</sub>O<sub>3</sub> acts as a source for ZnO-BCN
formation. The incorporation of ZnO onto BCN has extended the photoresponse
of ZnO in the visible region, which makes ZnO-BCN a preferable photocatalyst
relative to ZnO upon sunlight exposure. It is interesting to note
that as-prepared 2D ZnO-BCN sheets dispersed in PDMS form a stable
coating over aluminum alloys. The surface exhibited a water contact
angle (CA) of 157.6° with 66.6 wt % ZnO-BCN in polydimethylsiloxane
(PDMS) and a water droplet (7 μL) roll-off angle of <6°
and also demonstrates oil fouling resistant superhydrophobicity. In
brief, the present study focuses on the gram scale synthesis of a
new class of sunlight-driven photocatalyst and also its application
toward the development of superhydrophobic and oleophobic coating
