“…26 Cerium(III) chloride heptahydrate with ammonium hydroxide can form ceria nanorods, through a stirring procedure. 27,28 Cerium sulphate was used as a precursor in basic conditions, e.g., ammonia water 29 and sodium hydroxide. 30 Matin et al performed calcination at two different temperatures, where the shape, size, and distribution of nanoceria strongly inuence the surface properties.…”

“…The biomass microfiber filters can still function in harsh environment such as strong aicd (pH 2.2) and strong base (pH 11.8) condition, which is advantageous over those metal oxide or metal hydroxide-based filters [13,14,[28][29][30]. As shown in the inset of Figure 5b, the oil (1,2-dichloroethane) contact angle in water at pH 2.2 is higher than 153.8 • , indicating that the microfiber filters can still retain their underwater superoleophobicity at low pH.…”

Developing low-cost, durable, and high-performance materials for the separation of water/oil mixtures (free oil/water mixtures and emulsions) is critical to wastewater treatment and resource recovery. However, this currently remains a challenge. In this work, we report a biopolymer microfiber assembly, fabricated from the recovery of tissue waste, as a low-cost and high-performance filter for oily wastewater treatment. The microfiber filters demonstrate superhydrophilicity (water contact angle of 28.8°) and underwater superoleophobicity (oil contact angle of 154.2°), and thus can achieve separation efficiencies of >96% for both free oil/water mixtures and surfactant-stabilized emulsions even in highly acidic (pH 2.2)/alkaline (pH 11.8) conditions. Additionally, the prepared microfiber filters possess a much higher resistance to oil fouling than conventional membranes when filtering emulsions, which is because the large-sized 3D interconnected channels of the filters can delay the formation of a low-porosity oil gel layer on their surface. The filters are expected to practically apply for the oily wastewater treatment and reduce the amount of tissue waste entering the environment.

“…A. Matin et al have prepared superhydrophobic and superoleophobic surfaces on stainless steel mesh by using cerium oxide (CeO2) nanoparticles. The coated meshes exhibited a high value of water CA $150 and a very low angle for the model oil, hexadecane, that instantaneously wetted the surface (Matin et al 2018). X. P. Li et al have developed the hydrophobic CeO2 nanomaterials was synthesised via hydrothermal method without chemical modification with photocatalytic activity (Li et al 2018b).…”

This chapter is based on the recent literature on the superhydrophobic surface coated using various kinds of nanostructured materials (such as metal oxide and composite) and surface functionalizaton. Superhydrophobic surfaces repel water generally due to their surface texture or chemical properties, and surface possesses a high apparent contact angle (>150) and very low sliding angle (<5). Superhydrophobic coatings have received great attention worldwide for its multifunctional application in automotive, marine, and building sector.
