| 1 | Metal porphyrin intercalated reduced graphene oxide nanocomposite utilized for electrocatalytic oxygen reduction显示文摘In this paper, we report a simple and facile self-assembly method to successfully fabricate cationic metal porphyrin-MtTMPyP(Mt= Cobalt(Ⅱ), Manganese(Ⅲ), or Iron(Ⅲ); TMPyP = 5, 10, 15, 20-tetrakis(N-methylpyridinium-4-yl) porphyrin) intercalated into the layer of graphene oxide(GO) by the cooperative effects of electrostatic and π-π stacking interaction between positively charged metal porphyrin and negatively charged GO sheets. Followed by reduction with hydrazine vapor, a series of novel 2 D MtTMPyP/rGO_n were fabricated. The as-prepared 2 D hybrids were fully characterized and tested as non-noble metal catalysts for oxygen reduction reaction(ORR) in an alkaline medium. The MtTMPyP/rGO_n hybrids, especially CoTMPyP/rGO_5, demonstrated an improved electrocatalytic activity for ORR and a number of exchanged electrons close to 4-electron reaction, increased stability and excellent tolerance to methanol, showing a potential alternative catalyst for ORR in fuel cells and air batteries. | Mingyan Wang Qing Wang Wei Zhu Ying Yang Huixian Zhou Fan Zhang Lihua Zhou Joselito M.Razal Gordon G.Wallace Jun Chen | 2017 | Green Energy & Environment2017，2，3： | 3 |

| 3 | Synthesis of nitrogen-sulfur co-doped Ti_(3)C_(2)Tx MXene with enhanced electrochemical properties显示文摘Through material innovation,nanoscale structural design and hybrid manufacturing methods,great efforts have been made in developing high-performance energy storage systems.These devices can be comprised of twodimensional(2D)nanomaterials,such as MXene,and show promise for use in energy storage devices.In order to achieve better electrochemical properties of MXene,one crucial technique is to modify its structure by introducing defects or heteroatom dopants,which may expand the interlayer spacing and increase the ion transfer kinetics during the charge/discharge process.Here,a modified two-step multi-element strategy is explored utilizing ammonium citrate as intercalant and nitrogen source to enhance the level of heteroatom doping during annealing of MXene with sulfur.The resulting nitrogen/sulfur co-doped MXene displayed enhanced gravimetric capacitance(495 F g^(-1) at 1 A g^(-1)),outstanding rate capability(180 F g^(-1) at 10 A g^(-1))and excellent cycle stability(98%retention after 6000 charge/discharge cycles).The synthesis of NS-MXene reveals a novel and facile multiheteroatom pathway for functionalizing Ti_(3)C_(2)Tx MXene and demonstrates the potential variety of this family of modified MXenes that has yet to be explored,as well as unveils great promise for use in applications such as high performance supercapacitors. | Fangli Yang Dylan Hegh Dongxing Song Jizhen Zhang Ken Aldren S.Usman Chao Liu Zhiyu Wang Weigang Ma Wenrong Yang Si Qin Joselito M.Razal | 2022 | Materials Reports(Energy)2022，2，1： | 1 |
