Mesoporous Mn₃O₄ coated reduced graphene oxide for high-performance supercapacitor applications

Bio-Mediated Synthesis of Reduced Graphene Oxide Nanoparticles from Chenopodium album: Their Antimicrobial and Anticancer Activities

“…Thus, in the TEM images of RGOX many more wrinkle shapes can be observed with multiple layers stacked on each other. It is signified that the scrolled shape and lateral corrugations investigated by TEM [ 44 ].…”

Three-Dimensional Nanoporous CNT@Mn3O4 Hybrid Anode: High Pseudocapacitive Contribution and Superior Lithium Storage

“…The TEM images presented in Figure 1b,c demonstrate the anchoring of Mn 3 O 4 nanocrystals onto the sidewall of the CNTs. As depicted in Figure 1d, the observed lattice spacings of 2.78 Å and 3.36 Å correspond to the interplanar spacing of the (103) plane of Mn 3 O 4 (PDF card number 24-734) [15] and the (002) plane of CNTs (PDF card number 26-1079) [5], respectively. The Mn 3 O 4 coating sheath layer had a thickness of approximately 13 nm.…”

“…Applying Scherrer's formula, D = n•λ/(β•cos θ), we calculated a mean crystal size of ~20 nm for Mn 3 O 4 [16]. The N 2 sorption isotherm depicted in Figure 3a exhibits a type IV isotherm with a hysteresis loop, indicating the presence of mesopores [15,17]. The CNT@Mn 3 O 4 material demonstrated a remarkable specific surface area of 75.477 m 2 g −1 , a total pore volume of 0.1805 cm 3 g −1 , and an average pore size of 11.711 nm.…”

Pronounced effect of yttrium oxide on the activity of Pd/rGO electrocatalyst for formic acid oxidation reaction

“…When all oxygencontaining functional groups are eliminated, rGO individual sheets are formed, which are randomly aggregated and have dened edges and wrinkled surfaces. [46][47][48][49] Fine details about morphology and structural features of the synthesized material were studied by TEM analysis at 5 nm. Palladium nanoparticles and yttrium oxide nanoparticles (NPs) are uniformly dispersed on the surface of the rGO sheets (Fig.…”
