| 1 | Template-free synthesis of three-dimensional NiFe-LDH hollow microsphere with enhanced OER performance in alkaline media显示文摘Flower-like hierarchical three-dimensional Ni Fe layered double hydroxides hollow microspheres(3D NiFe-LDH HMS),as one kind of novel non-noble metal electrocatalysts,have been fabricated in a templatefree route for water oxidation.Both of the concentration of ammonium fluoride and the reaction time are adjusted to obtain a series of Ni Fe-LDH microspheres,with different internal structures from massive to hollow generated during the hydrothermal treatment,which improve the electrocatalytic activity of the Ni Fe-LDH catalysts towards the evolution reaction of oxygen.The optimized Ni Fe-LDH-0.4M HMS show the excellent OER performance in alkaline electrolyte withη=290 mV@10 mA cm^-2,and a Tafel slope of 51 mV dec-1,which outperforms the benchmark RuO2 catalyst.The possible reason is attributed to the more exposure of active sites,and fast ion transport resulting from the hierarchical hollow structure. | Haihong Zhong Tongyuan Liu Shuwei Zhang Dianqing Li Pinggui Tang Nicolas Alonso-Vante Yongjun Feng | 2019 | Journal of Energy Chemistry2019，28，6： | 5 |

| 4 | Improving thermal stability and light fastness of Acid Red 114 by incorporating its anions in a ZnAl-layered double hydroxides matrix显示文摘Incorporation of anions of Acid Red 114 dye(1,3-naphthalenedisulfonic acid,8-[2-[3,3-dimethyl-4-[2-[4- [[(4-methylphenyl)sulfonyl]oxy]phenyl]diazenyl][1,1-biphenyl]-4-yl]diazenyl]-7-hydroxy-,disodium salt)(denoted as NPDA)into ZnAl-layered double hydroxides(LDHs)has been carried out by an anion- exchange method in an effort to improve their thermal stability and light fastness.After intercalation of NPDA anions,the interlayer distance of the LDHs increases from 0.87 to 2.18 nm,confirming their incorporation into the interlayer galleries of the LDHs host.Infrared spectroscopy and thermogravimetric analysis revealed the presence of host-guest interactions between LDHs layers and NPDA anions.The thermal stability of NPDA and ZnAl-NPDA-LDHs was compared by thermogravimetric-differential thermal analysis,UV-visible spectroscopy and infrared spectroscopy.It was found that the thermal stability of NPDA anions was markedly improved by incorporation into the ZnAl-LDHs matrix,while the light fastness was also enhanced. | Haifeng Zhu Liren Wang Pinggui Tang Yongjun Feng Dianqing Li | 2012 | Particuology2012，10，4： | 0 |
| 5 | Tuning the atomic configuration environment of MnN_(4) sites by Co cooperation for efficient oxygen reduction显示文摘Carbon-based N-coordinated Mn(Mn-N_(x)/C)single-atom electrocatalysts are considered as one of the most desirable non-precious oxygen reduction reaction(ORR)candidates due to their insignificant Fenton reactivity,high abundance,and intriguing electrocatalytic performance.However,current MnN_(x)/C single-atom electrocatalysts suffer from high overpotentials because of their low intrinsic activity and unsatisfactory chemical stability.Herein,through an in-situ polymerization-assisted pyrolysis,the Co as a second metal is introduced into the Mn-N_(x)/C system to construct Co,Mn-N_(x)dual-metallic sites,which atomically disperse in N-doped 1D carbon nanorods,denoted as Co,Mn-N/CNR and hereafter.Using electron microscopy and X-ray absorption spectroscopy(XAS)techniques,we verify the uniform dispersion of CoN4and MnN4atomic sites and confirm the effect of Co doping on the MnN_(4) electronic structure.Density functional theory(DFT)calculations further elucidate that the energy barrier of ratedetermining step(^(*)OH desorption)decreases over the 2 N-bridged MnCoN_(6) moieties related to the pure MnN_(4).This work provides an effective strategy to modulate the local coordination environment and electronic structure of MnN_(4) active sites for improving their ORR activity and stability. | Jing Wang Haihong Zhong Jun Yang Huiyu Li Pinggui Tang Yongjun Feng Dianqing Li | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
