1层状水滑石结构包覆钴硼合金的电化学产氧性能(英文)显示文摘电解水制氧是一种非常有吸引力的转化储存间歇式能源的技术.本文着重研究了非晶态钴硼合金的电解水产氧性能.非晶态钴硼合金可以通过硼氢化钠直接还原钴盐来获取,并表现出较高的电化学活性.对钴硼合金的弱氧化,产生了类水滑石结构的钴氢氧化物,可进一步提高该类催化剂的整体催化活性,达到接近商业催化剂水平.冷雪 吴光栩 苏并坚 张凌云 Ian R.Gentle 王大伟 2017Chinese Journal of Catalysis2017,38,6:2
2溶液相合成卤化石墨烯及其对氧化还原反应的电催化活性(英文)显示文摘Metal-free carbon electrocatalyts for the oxygen reduction reaction (ORR) are attractive for their high activity and economic advantages. However, the origin of the activity has never been clearly elucidated in a systematic manner. Halogen group elements are good candidates for elucidating the effect, although it has been a difficult task due to safety issues. In this report, we demonstrate the synthesis of Cl-, Br- and I-doped reduced graphene oxide through two solution phase syntheses. We have evaluated the effectiveness of doping and performed electrochemical measurements of the ORR activity on these halogenated graphene materials. Our results suggest that the high electroneg-ativity of the dopant is not the key factor for high ORR activity; both Br- and I-doped graphene promoted ORR more efficiently than Cl-doped graphene. Furthermore, an unexpected sulfur-doping in acidic conditions suggests that a high level of sulfide can degrade the ORR activity of the graphene material.Kuang-Hsu Wu Da-Wei Wang Qingcong Zeng Yang Li Ian R.Gentle 2014催化学报2014,35,6:1
3“Soft” graphene oxide-organopolysulfide nanocomposites for superior pseudocapacitive lithium storage显示文摘We report a 'soft' graphene oxide-polymeric organosulfide nanocomposite with improved pseudocapacitive performance for high-potential(1–2.8 V vs. Li^0/Li^+), high-capacity(278 mAh/g) and stable(500 cycles) lithium storage.Yang Li Qingcong Zeng Ian R.Gentle Da-Wei Wang 2018Chinese Chemical Letters2018,29,4:0
4Zinc–Bromine Rechargeable Batteries:From Device Configuration,Electrochemistry,Material to Performance Evaluation显示文摘Zinc–bromine rechargeable batteries(ZBRBs)are one of the most powerful candidates for next-generation energy storage due to their potentially lower material cost,deep discharge capability,non-flammable electrolytes,relatively long lifetime and good reversibility.However,many opportunities remain to improve the efficiency and stability of these batteries for long-life operation.Here,we discuss the device configurations,working mechanisms and performance evaluation of ZBRBs.Both non-flow(static)and flow-type cells are highlighted in detail in this review.The fundamental electrochemical aspects,including the key challenges and promising solutions,are discussed,with particular attention paid to zinc and bromine half-cells,as their performance plays a critical role in determining the electrochemical performance of the battery system.The following sections examine the key performance metrics of ZBRBs and assessment methods using various ex situ and in situ/operando techniques.The review concludes with insights into future developments and prospects for high-performance ZBRBs.Norah S.Alghamdi Masud Rana Xiyue Peng Yongxin Huang Jaeho Lee Jingwei Hou Ian R.Gentle Lianzhou Wang Bin Luo 2023Nano-Micro Letters2023,15,11:0
