“…The spent FCC catalyst are mainly treated via landfill 10 . Some researcher explore the coating of spent FCC catalyst as anticorrosive and antimicrobial material, other researcher uses the spent FCC catalyst to recover the precious metal and rare earth, and use spent FCC catalyst as admixtures in mortar and concrete production 11 – 13 . Zeolite Y is the main components of the FCC catalyst 14 .…”

The spent fluid catalytic cracking (FCC) catalyst has been loaded with ferric oxide (Fe 2 o 3) and titanium dioxide (TiO 2). Fe-Ti/SF composite (loaded with 5 wt% TiO 2 and 5 wt% Fe 2 o 3), Fe/SF composite (loaded with10 wt% Fe 2 o 3) and Ti/SF composite (loaded with 10 wt% TiO 2) have been fabricated via a modified-impregnation method. The band gaps of the Fe-Ti/SF, Fe/SF and Ti/SF composites (evaluated by the energy versus [F(R∞)hv] n) are 2.23, 1.98 and 3.0 eV, respectively. Electrochemical impedance spectroscopy shows that the Fe-Ti/SF has lower electron transfer resistance, it has the small charge transfer resistance and fast charge transfer rate. The interparticle electrons transfer between the fe 2 o 3 and tio 2 , which can improve the separation of the photo-electrons and holes. The holes transfer from valence band of TiO 2 to the valence band of Fe 2 o 3 , which can provide more active sites around the adsorbed molecules. The methylene blue degradation efficiencies (with the Fe-Ti/SF, Fe/SF and Ti/ SF composites) are ~ 94.2%, ~ 22.3% and ~ 54.0% in 120 min, respectively. This work reveals that the spent fcc catalyst as supporter can be loaded with fe 2 o 3 and tio 2. This composite is highly suitable for degradation of methylene blue, which can provide a potential method to dispose the spent FCC catalyst in industry.

“…Carbon steel is widely used in bridges, ships, pipelines, automobiles and other fields [1], but the economic loss caused by steel corrosion is inestimable [2]. Conversion coatings, especially phosphate conversion coatings, are widely applied to carbon steel, and improve its anticorrosion performance [3,4].…”

Preparation of Zn5Mo2O11·5H2O@Sulfonated Graphene by Template Method and Its Anticorrosion Mechanism in Polyurethane Coatings

Currently, waterborne coatings are widely used, but their poor anticorrosion performance compared with solvent-based coatings hinders their further application. In this study, a series of Zn5Mo2O11·5H2O@sulfonated graphene (SZMO@SG) composites are prepared using the template method. SZMO@SG is a type of two-dimensional material with a large diameter and low thickness compared to traditional zinc molybdate. Combining SZMO@SG with waterborne hydroxy acrylic latex and isocyanate, the polyurethane coatings with 3 wt% SZMO@SG achieve the best anticorrosion performance in the 3.5 wt% NaCl immersion test. In electrochemical impedance spectroscopy (EIS), the charge transfer resistance (Rct) of polyurethane coatings with 3 wt% SZMO@SG reaches 283,100 Ω·cm2 after soaking in a 3.5 wt% NaCl solution for 48 h. Its corrosion potential and corrosion current are only −0.453 V and 1.71 × 10−3 mA/cm2, respectively. After metal substrate corrosion, the metal substrate of polyurethane coatings with SZMO@SG contain more Mo, Zn and low-state Fe atoms. It confirms that a passivation film was deposited on the metal substrate and prevents Fe from oxidation. The elemental content and distribution of the coatings after the NaCl solution immersion test indicate that SZMO@SG may have the Na+ adsorption function.
