“…As shown in Figure b‐d, when the current density is increased to 0.20 mA cm −2 , the NCFC based Li‐O 2 battery can work more than 400 cycles with the maximum overpotential of 0.92 V, and it always maintains a low charging platform potential (less than 3.00 V). Under the same conditions, the SP based Li‐O 2 battery can only work 188 cycles with the maximum overpotential of 1.69 V, and the charging platform potential up to 3.98 V. In reported literatures, many Li‐O 2 batteries under similar conditions were usually able to work for less than 150 cycles, with the charging platform potential greater than 4.00 V and overpotential greater than 1.00 V . In addition, NCFC based Li‐O 2 batteries always maintain higher energy efficiency.…”

Nitrogen-doped porous carbon obtained from silk cocoon (NCFC) was first used as cathodes for Li-O 2 batteries with ionic liquid in this paper. NCFC is made up of irregular bending slices and has a high specific discharge product of most Li-O 2 surface area of 2142.0 m 2 g À 1 which means numerous active sites for electrochemical reactions. The results show that NCFC based Li-O 2 battery has good cycle stability and high energy efficiency under different current density. In particular, NCFC based Li-O 2 batteries can work more than 400 cycles (500 mAh g À 1 at 0.20 mA cm À 2 ) with the maximum overpotential less than 0.92 V, which is much better than super P based Li-O 2 batteries (188 cycles with overpotential up to 1.88 V) and many reported Li-O 2 batteries. The results show that NCFC is a very promising material for Li-O 2 batteries.[a] J.

“…Combined with the fact that cobalt is now included in the list of critical raw materials [59], there is a strong interest to at least partially replace some Co in Co 3 O 4 -based materials by cheaper and more ecofriendly metals. In this direction, Li et al [60] reported the synthesis of 3D ordered mZnCo 2 O 4 (3DOM (three-dimensional ordered mesoporous) ZnCo 2 O 4 ) via a wetness impregnation approach, using KIT-6 silica as a template and Zn and Co nitrates as precursors. The obtained material had a relatively high BET SSA of 127 m 2 /g with a narrow pore size distribution, centered at 3.4 nm.…”

Mesoporous Nanocast Electrocatalysts for Oxygen Reduction and Oxygen Evolution Reactions

2019

View full text Add to dashboard Cite

Catalyzed oxygen evolution and oxygen reduction reactions (OER and ORR, respectively) are of particular significance in many energy conversion and storage processes. During the last decade, they emerged as potential routes to sustain the ever-growing needs of the future clean energy market. Unfortunately, the state-of-the-art OER and ORR electrocatalysts, which are based on noble metals, are noticeably limited by a generally high activity towards one type of reaction only, high costs and relatively low abundance. Therefore, the development of (bi)functional low-cost non-noble metal or metal-free electrocatalysts is expected to increase the practical energy density and drastically reduce the production costs. Owing to their pore properties and high surface areas, mesoporous materials show high activity towards electrochemical reactions. Among all synthesis methods available for the synthesis of non-noble mesoporous metal oxides, the hard-templating (or nanocasting) approach is one of the most attractive in terms of achieving variable morphology and porosity of the materials. In this review, we thus focus on the recent advances in the design, synthesis, characterization and efficiency of non-noble metal OER and ORR electrocatalysts obtained via the nanocasting route. Critical aspects of these materials and perspectives for future developments are also discussed.
