1Size-tunable synthesis of gold nanorods using pyrogallol as a reducing agent显示文摘A novel and facile seed-mediated method for the preparation of monodispersed gold nanorods(GNRs) is presented by introducing pyrogallol as a reductant. Fast Fourier transformation of high-resolution transmission electron microscopy reveals that the synthesized GNRs are single crystalline. The longitudinal surface plasmon resonance of GNRs can be finely tuned by varying silver ion concentrations or seed amounts. Also, both thick(diameter >30 nm) and thin(diameter <10 nm) GNRs with exceptional monodispersity can be well prepared by this method. These findings indicate that this method has a greater performance in controlling the morphology of GNRs than that of traditional approach with ascorbic acid as a reductant.Yuanfu Huang Kai Xia Nongyue He Zhuoxuan Lu Liming Zhang Yan Deng Libo Nie 2015Science China Chemistry2015,58,11:3

4Supramolecular-mediated ball-in-ball porous carbon nanospheres for ultrafast energy storage显示文摘Hierarchical porous carbons are the most viable electrode material for supercapacitors because of their balanced capacitive performance and chemical stability.Their pore connectivity plays a pivotal role in electrolyte transport,which is quantified by a new parameter,defined in this work as the longest possible pore separation(LPPS).Herein,we report hierarchical porous carbon nanospheres(HPC-NS)with a unique ball-in-ball structure,which is achieved by the pyrolysis of a supramolecular complex ofγ-cyclodextrin(γ-CD)/PEO-PPO-PEO(F127).This approach differs from the conventional softtemplating method in that,apart from the assembly of the monomicelles that leads to the host nanospheres(approximately 300 nm),theγ-CD-containing monomicelles themselves are converted to small porous carbon nanospheres(<10 nm),which results in an ultralow LPPS of 10 nm,representing the bestknown pore connectivity of the HPC family.The HPC-NS delivers a high specific capacitance(405 F g^(-1)at 1 A g^(-1)and 71%capacitance retention at 200 A g^(-1)),wide voltage window(up to 1.6 V),and simultaneously high energy and power densities(24.3 Wh kg^(-1)at a power density of 151 W kg^(-1)and 9 Wh kg^(-1)at 105 W kg^(-1))in aqueous electrolytes.This new strategy boosts the development of porous carbon electrodes for aqueous supercapacitors with simultaneously high power and energy densities.Lei Yao Junsheng Lin Yuanyuan Chen Xiujuan Li Dongrui Wang Haitao Yang Libo Deng Zijian Zheng 2022InfoMat2022,4,4:1
5Mutual Self‑Regulation of d‑Electrons of Single Atoms and Adjacent Nanoparticles for Bifunctional Oxygen Electrocatalysis and Rechargeable Zinc‑Air Batteries显示文摘Rechargeable zinc-air batteries(ZABs)are a promising energy conversion device,which rely critically on electrocatalysts to accelerate their rate-determining reactions such as oxygen reduction(ORR)and oxygen evolution reactions(OER).Herein,we fabricate a range of bifunctional M-N-C(metal-nitrogen-carbon)catalysts containing M-Nx coordination sites and M/MxC nanoparticles(M=Co,Fe,and Cu)using a new class ofγ-cyclodextrin(CD)based metal-organic framework as the precursor.With the two types of active sites interacting with each other in the catalysts,the obtained Fe@C-FeNC and Co@C-CoNC display superior alkaline ORR activity in terms of low half-wave(E1/2)potential(~0.917 and 0.906 V,respectively),which are higher than Cu@C-CuNC(~0.829 V)and the commercial Pt/C(~0.861 V).As a bifunctional electrocatalyst,the Co@C-CoNC exhibits the best performance,showing a bifunctional ORR/OER overpotential(ΔE)of~0.732 V,which is much lower than that of Fe@C-FeNC(~0.831 V)and Cu@C-CuNC(~1.411 V),as well as most of the robust bifunctional electrocatalysts reported to date.Synchrotron X-ray absorption spectroscopy and density functional theory simulations reveal that the strong electronic correlation between metallic Co nanoparticles and the atomic Co-N4 sites in the Co@C-CoNC catalyst can increase the d-electron density near the Fermi level and thus effectively optimize the adsorption/desorption of intermediates in ORR/OER,resulting in an enhanced bifunctional electrocatalytic performance.The Co@C-CoNC-based rechargeable ZAB exhibited a maximum power density of 162.80 mW cm^(−2) at 270.30 mA cm^(−2),higher than the combination of commercial Pt/C+RuO2(~158.90 mW cm^(−2) at 265.80 mA cm^(−2))catalysts.During the galvanostatic discharge at 10 mA cm^(−2),the ZAB delivered an almost stable discharge voltage of 1.2 V for~140 h,signifying the virtue of excellent bifunctional ORR/OER electrocatalytic activity.Sundaram Chandrasekaran Rong Hu Lei Yao Lijun Sui Yongping Liu Amor Abdelkader Yongliang Li Xiangzhong Ren Libo Deng 2023Nano-Micro Letters2023,15,4:1
6In-situ encapsulation ofα-Fe_(2)O_(3) nanoparticles into ZnFe_(2)O_(4) micro-sized capsules as high-performance lithium-ion battery anodes显示文摘Transition metal oxides as anode materials for high-performance lithium-ion batteries suffer from severe capacity decay,originating primarily from particle pulverization upon volume expansion/shrinkage and the intrinsically sluggish electron/ion transport.Herein,in-situ encapsulation ofα-Fe_(2)O_(3) nanoparticles into micro-sized ZnFe_(2)O_(4) capsules is facilely fulfilled through a co-precipitation process and followed by heat-treatment at optimal calcination temperature.The porous ZnFe_(2)O_(4) scaffold affords a synergistic confinement effect to suppress the grain growth ofα-Fe2 O3 nanocrystals during the calcination process and to accommodate the stress generated by volume expansion during the charge/discharge process,leading to an enhanced interfacial conductivity and inhibit electrode pulverization and mechanical failure in the active material.With these merits,the preparedα-Fe_(2)O_(3)/Fe_(2)O_(4) composite delivers prolonged cycling stability and improved rate capability with a higher specific capacity than soleα-Fe_(2)O_(3) and Fe_(2)O_(4).The discharge capacity is retained at 700 mAh g-1 after 500 cycles at 200 mA g^(-1) and 940 mAh g^(-1) after 50 cycles at 100 m A g^(-1).This work provides a new perspective in designing transition metal oxides for advanced lithium-ion batteries with superior electrochemical properties.Wei Wu Yongshan Wei Hongjiang Chen Keyan Wei Zhitong Li Jianhui He Libo Deng Lei Yao Haitao Yang 2021Journal of Materials Science & Technology2021,,16:1
7Coupling of piezocatalysis and photocatalysis for efficient degradation of methylene blue by Bi_(0.9)Gd_(0.07)La_(0.03)FeO_(3) nanotubes显示文摘Photocatalytic degradation of organic pollutants is of great significance for wastewater remediation but is still hindered by the poor catalytic efficiency of the catalysts.Herein,we report a strategy to simultaneously introduce piezocatalysis and to enhance the intrinsic photocatalysis in a single catalyst,which improved the performance for catalytic degradation of methylene blue(MB)significantly.Specifically,piezoelectric BiFeO_(3)(BFO)nanotube doped with different contents of Gd and La(Bi_(0.9)(GdxLa_(1−x))0.1FeO_(3))were produced by electrospinning.The doping led to a higher concentration of surface oxygen vacancy(OV)in Bi_(0.9)Gd_(0.07)La_(0.03)FeO_(3),which effectively increased the piezoelectric field due to the deformation of BFO,and suppressed the recombination of photon-generated electron–hole pairs.The Bi_(0.9)Gd_(0.07)La_(0.03)FeO_(3)nanotube showed excellent catalytic performance under simultaneous light irradiation and ultrasonic excitation,giving an extraordinary 95%degradation of MB within 90 min.These findings suggest that the piezoelectric effect combined with defect engineering can enhance the catalytic performance of Bi_(0.9)Gd_(0.07)La_(0.03)FeO_(3)nanotube.This could potentially be extended to other catalytic systems for high-performance pollutant treatment.Angom Devadatta MANI Jie LI Ziquan WANG Jiale ZHOU Huaicheng XIANG Jinlai ZHAO Libo DENG Haitao YANG Lei YAO 2022Journal of Advanced Ceramics2022,11,7:0
