1. A method for producing a multifunctional particle, the method comprising:
- contacting a hydrophobic silane to a surface of a silica particle comprising a diatomaceous earth particle, a fused silica particle or a rice husk ash particle to chemically bond the hydrophobic silane to at least a portion of the surface of the silica particle;
contacting a silane coupling agent to the surface of the silica particle to chemically bond the silane coupling agent to at least a portion of the surface of the silica particle;
rinsing the silica particle with a solvent after contacting at least one of the hydrophobic silane or the silane coupling agent to remove impurities and to remove any of the at least one of the hydrophobic silane or the silane coupling agent that are unattached to the silica particle; and
wherein the multifunctional particle is superhydrophobic and chemically reactive.
