Corrosion behavior of Mg–Al LDH film in-situ assembled with graphene on Mg alloy pre-sprayed Al layer

Anti‐Acidification and Immune Regulation by Nano‐Ceria‐Loaded Mg–Al Layered Double Hydroxide for Rheumatoid Arthritis Therapy

“…The resultant fitting peak located at 1305.85 and 74.35 eV are ascribed to Mg 1s (Figure S5a, Supporting Information) and Al 2p (Figure S5b, Supporting Information), respectively, indicating the presences of Mg 2+ and Al 3+ in the composite materials from MgAl‐LDH. [ 26 ] The Ce 3+ /Ce 4+ ratio is 36.68/63.32%, as quantified from the fitting peaks of Ce 3d attributed to Ce 3+ (882.7, 888.5, 898.35, 917 eV) and Ce 4+ (885.6, 901.9 eV), which favors the antioxidation activity elevation of CeO 2 NPs of high‐enough Ce 3+ percentages (Figure S5c, Supporting Information). [ 8b ] Also, O 1s band could be deconvoluted into four sub‐bands as “metal‐O” (M‐O, 531.5 eV), “H‐O” (532.1 eV), “Ce‐O” (530.6 eV) and H 2 O (533.1 eV) (Figure S5d, Supporting Information), further verifying the successful preparation of LDH‐CeO 2 .…”

Synthesis and characterization of polyaniline–hydrotalcite–graphene oxide composite and application in polyurethane coating

“…It is due to the anticorrosion mechanism of HG, which is explained as the ion exchangeable hydrotalcite to trap Cl − , as well as electron trapping of graphene to reduce the erosion of the medium. 74 However, Cl − ion exchange and electron trapping of HG have limited capability. Therefore, the R C of PU(HG) decreased to 1.91 × 10 3 Ω cm 2 , and then 0.40 × 10 3 Ω cm 2 after 20 days and 30 days, respectively.…”
