We developed a single-step thermal method that enables successful inclusion of ZnO components in the porous boron鈥揷arbon鈥搉itrogen (BCN) framework to form a new class of functional hybrid. ZnO-containing BCN hybrids were prepared by treating a mixture of B₂O₃, glycine, and zinc nitrate at 500 掳C. Glycine鈥搉itrate decomposition along with B₂O₃ 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掳 with 66.6 wt % ZnO-BCN in polydimethylsiloxane (PDMS) and a water droplet (7 渭L) roll-off angle of <6掳 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.
