In this work, three-dimensional porous Ni–Co layered double hydroxide nanosheets are vertically decorated on N-doped reduced graphene oxide <italic>via</italic> a simple one-step microwave-assisted hydrothermal process.
This work reported Co9S8 nanoparticle-decorated carbon nanofibers (CNF) as a supercapacitor electrode. By using mild ion-exchange method, the cobalt oxide-based precursor nanoparticles were transformed to in microwave hydrothermal process, and these decorated onto nanofiber backbone. The composition of can be readily tuned by varying Co acetate content precursor. porous offered fast electron transfer pathway while well dispersed acted redox center for energy storage. As result, high specific...
A multi-hierarchical responsive selenium- and tellurium-containing block copolymer that can be stepwise oxidized by both chemical methods electrochemical methods.
The relationship between the ORR catalytic activity of LaMnO 3+ δ and its Mn–O bond length was examined by replacing La with Sr, it found that shorter length, higher activity.
Chemical substitution is an effective way to improve electrocatalytic properties in transition metal oxides. We investigate the synergistic effect between Fe4+ and Co4+ ions on catalytic activity for oxygen evolution reaction (OER) Fe–Co-mixed perovskite oxide CaFe1−xCoxO3. The OER of CaFe1−xCoxO3 substantially increased by small amounts Co (Fe) doping into CaFeO3 (CaCoO3), leading superiority compared pure Fe x dependences overpotential specific (0.05 ≦ 0.95) are expressed constant offset...
Zn–air batteries (ZABs) are highly promising energy conversion devices primarily because of their high densities and environmental friendliness. In such devices, the efficiency stability catalyst for oxygen reduction reaction (ORR) at cathode have a significant effect on battery performance. Therefore, in this study, we investigated ORR catalytic activities series Co-substituted nonstoichiometric LaMn1–xCoxO3+δ perovskite oxides explored potential as catalysts ZABs. We found that amount Co...
Abstract YIn 1- x Mn O 3 is a newly discovered inorganic blue pigment whose vivid color results from MnO 5 trigonal bipyramidal (TBP) polyhedra. Recently, it has been reported that commercial powders exhibit temperature-induced change, i.e. thermochromism. In this study, we investigate the thermochromism and crystal structure evolution of synthetic 0.9 0.1 powders. We observe at RT gradually changed to dark with increasing temperature. This mainly attributed broadening optical absorption...
By using a high-contrast grating (HCG, high transmittance <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline" id="m1"> <mml:mrow> <mml:mo form="prefix">></mml:mo> <mml:mn>90</mml:mn> <mml:mo>%</mml:mo> </mml:mrow> </mml:math> ) to control the phase shift of incident light, we theoretically designed novel-structured HCG-integrated superconducting nanowire single-photon detector (HCG-SNSPD) with high-efficiency and large light-receiving area. Without enlarging typical...
Abstract This study sought to achieve fluorine doping into the surface structure of LiNi 0.6 Co 0.2 Mn O 2 (NCM622) cathodes for use in lithium‐ion batteries by atomic layer deposition method improve structural stability and electrochemical performance. Thin‐film electrodes were used clearly understand fundamental effects properties. Based on our observations, oxygen vacancy that basically exists NCM622 thin‐film electrode triggers additional formation derivatives with a spinel‐like phase,...

Perovskite oxides (ABO3) containing Mn have received considerable attention because of their relatively high catalytic activity for the oxygen reduction reaction (ORR) and low preparation cost. In ORR, both adsorption O2 desorption OH‒ on surface significantly affect efficiency catalysis, which can be changed by Mn-O bond length. this study, effect length ORR in nonstoichiometric (LaMn)1-xO3 was investigated changing number cation vacancies via heat treatment air to further enhance activity....
