Report: Photoelectrochemically Rechargeable Zn-Air Batteries
This work aims to design photoelectrochemically rechargeable Zn-air batteries with improved energy and power density, energy efficiency and cycle life. Our plan is to solve the bottle-neck problem associated with air electrocatalysts by developing novel nanocarbon-inorganic hybrid materials for oxygen reduction and/or evolution with high efficiency and durability. Also, we are pursuing active a...
متن کاملIntegrating NiCo Alloys with Their Oxides as Efficient Bifunctional Cathode Catalysts for Rechargeable Zinc-Air Batteries.
The lack of high-efficient, low-cost, and durable bifunctional electrocatalysts that act simultaneously for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) is currently one of the major obstacles to commercializing the electrical rechargeability of zinc-air batteries. A nanocomposite CoO-NiO-NiCo bifunctional electrocatalyst supported by nitrogen-doped multiwall carb...
متن کاملSpherical nitrogen-doped hollow mesoporous carbon as an efficient bifunctional electrocatalyst for Zn-air batteries.
Materials based upon porous carbon have gained considerable attention due to their high surface area, electric conductivity, thermal and chemical stability, low density, and availability. These superior properties make them ideal for diverse applications. Doping these carbon nanostructures holds promise of designing the properties of these structures and opening the door to practical applicatio...
متن کاملPlatinum-gold nanoparticles: a highly active bifunctional electrocatalyst for rechargeable lithium-air batteries.
PtAu nanoparticles (NPs) were shown to strongly enhance the kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in rechargeable Li-O(2) cells. Li-O(2) cells with PtAu/C were found to exhibit the highest round-trip efficiency reported to date. During ORR via xLi(+) + O(2) + xe(-) --> Li(x)O(2), the discharge voltage with PtAu/C was considerably higher than that of...

0.1016/j.nanoen.2 lsevier Ltd. All rig thors. uthor. : [email protected] Abstract Development of efficient bifunctional electrocatalysts from earth abundant elements, simultaneously active for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), remains to be a grand challenge for electrocatalysis. Herein we firstly synthesized a new type of bifunctional catalyst (NCNT/CoxMn1 xO)...
