Reduced graphene oxide encapsulated perovskite-type lanthanum cobalt oxide nanoparticles for efficient electrolysis of water to oxygen reactions (OER/ORR)

CeO2/CuO/NiO hybrid nanostructures loaded on N-doped reduced graphene oxide nanosheets as an efficient electrocatalyst for water oxidation and non-enzymatic glucose detection

“…6g). 29,31,78–83 The high activity of CeO 2 /CuO/NiO@N-rGO is related to the synergistic catalytic effect of the CeO 2 /CuO/NiO nanoparticles and N-doped rGO. 84 The OER catalytic kinetics of the as-prepared catalysts were determined from the slope of their corresponding Tafel curves.…”

“…Meanwhile, metal oxides supported on reduced graphene oxide are not left behind. For example, composites such as CeO 2 nanoparticles grown on reduced graphene oxide sheets, 27 CoNiO 2 @rGO/NF, 28 flower-like Co3Ni1B–rGO, 29 CuCo 2 S 4 @rGO, 30 LaCoO 3 @rGO 31 and so on were used for electrochemical water oxidation in the literature.…”

Strategic Design and Insights into Lanthanum and Strontium Perovskite Oxides for Oxygen Reduction and Oxygen Evolution Reactions

“…Thus, it is seen that Mondal et al [107] developed a 2D heterojunction composite of Pr 0.5 Ba 0.5 Mn 1.8−x Nb x Co 0.2 O 6−𝛿 (PBMNC-x, x = 0-0.3, 𝛿 = 0.38-0.59) nanosheets and NiFe-LDH through a hydrothermal method. A cobalt doped LaMnO 3 perovskite [108] plus potassium was substituted into LaMnO 3 to form LKMO via the hydrothermal method. [109] The La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3−𝛿 (LSCF) composite, as prepared by the hydrothermal method, followed by silver decoration on LSCF plus coating of graphene, was carried out via chemical deposition, producing Ag/LSCF@graphene.…”

Zr and Ir Codoped Perovskite Nanosheets for Efficient and Stable Oxygen Evolution

“…However, the high-temperature sintering process used in perovskite synthesis often results in severe particle agglomeration, limiting active-site exposure . To address this, preparing perovskite catalysts with a high specific surface area is an effective method for improving activity. , And the two-dimensional nanosheet is explored as an ideal configuration due to the short mass-transfer distance and abundant active sites . Despite this, the enhancement of intrinsic site activity remains the more attractive approach as compared to morphology regulation.…”
