In this work,a facile wet chemical procedure was used to synthesize ring-like Pt-Bi graphene-based catalyst(Pt-Bi/GNs(Etching)).After etching by nitric acid,most Bi species in Pt-Bi bimetallic catalys
In this work,Platinum-gold/graphene bimetallic catalysts(Pt-Au/GNs) were synthesized through one-pot microwave assisted method with alcohol as a reducing agent.
The development of low cost,active and stable non-precious metal(TiO2) catalysts to replace commercial Pt-based catalysts for oxygen reduction reaction(ORR) is a hot topic to this day.
Porous carbon materials,due to their appealing properties of large surface area,high electric conductivity,and excellent chemical stability,show broad range of applications in electrochemical energy-s
The high cost and insufficient performance of noble metal-based oxygen reduction reaction(ORR) electrocatalysts in both fuel cells and metal-air batteries is a major barrier for their commercial appli
The reasonable design of sulfur cathode which can relieve the effects of polysulfides shutting is the first step to commercialization of lithium-sulfur batteries.In this work,CoS nanosheets were direc
Sulfonated poly(ether ether ketone)(SPEEK,SP) with tetraethoxysilane(TEOS) and diethylethylammonium trifluoromethanesulfonate([dema] [OTf]) were used to make SP/SiOx/OTf inorganic–organic composite me
LiV3O8/10 wt. ％poly(1,5-diaminoanthraquinone) composite is prepared simply by a chemical oxidative polymerization process and applied as cathode materials for rechargeable lithium batteries.
发展大规模储能的二次电池不仅需要具有适宜的电化学性能,更需考虑资源成本和环境效益等应用要求.而锂离子电池用于大规模储能可能受到锂资源的制约,因此,从资源与环 境方面考虑,具有与锂离子电池相似电化学性能的钠离子电池体系作为储能电池更具应用优势.碳材料是最具应用前景的储钠负极材料,然而,有关硬碳储钠机理仍存在争议.
The carbonized melamine formaldehyde foam has been modified with thin titanium layer and then used as an inexpensive and lightweight current collector.By depositing the silicon film on the thin Ti lay
