“…Through painting or brushing metal nitrates onto inactive substrate such as Ti, Ni, fluorine-doped tin oxide (FTO), and stainless foam, spinel composites can be formed on functional substrates. ,− Impregnating the metal nitrates into porous carbon and (La,Sr)MnO 3 -yttria with good dispersion results in spinel oxides in porous frameworks. − Additionally, nanocasting technology with soft or hard templates such as silica xerogel and metal nitrates as raw material is used to prepare porous spinel nanoparticles. ,− Their specific surface areas are up to 250 m 2 g –1 (Mg-substituted Co 3 O 4 ) . In the example of the fabrication of Mn 3 O 4 /CMK-3 nanohybrids, mesoporous CMK-3 was first dispersed in a mixed solution of H 2 O and ethanol containing the Mn(NO) 3 .…”

“…fabricated cathodes of Co 1.5 Mn 1.5 O 4 (20–30 nm) nanocrystals infiltrated into (La,Sr)MnO 3 –YSZ, which greatly reduced both ohmic resistance (0.136 Ω cm 2 at 700 °C) and polarization resistance in the cells. This could be attributed to the high catalytic oxygen reduction activity of the nanosized Co 1.5 Mn 1.5 O 4 coupled with the highly reversible Mn 3+ /Mn 4+ redox . Preparing mixed-valent pairs in nonstoichiometric composites is also an effective method.…”

Spinels with the formula of ABO (where A and B are metal ions) and the properties of magnetism, optics, electricity, and catalysis have taken significant roles in applications of data storage, biotechnology, electronics, laser, sensor, conversion reaction, and energy storage/conversion, which largely depend on their precise structures and compositions. In this review, various spinels with controlled preparations and their applications in oxygen reduction/evolution reaction (ORR/OER) and beyond are summarized. First, the composition and structure of spinels are introduced. Then, recent advances in the preparation of spinels with solid-, solution-, and vapor-phase methods are summarized, and new methods are particularly highlighted. The physicochemical characteristics of spinels such as their compositions, structures, morphologies, defects, and substrates have been rationally regulated through various approaches. This regulation can yield spinels with improved ORR/OER catalytic activities, which can further accelerate the speed, prolong the life, and narrow the polarization of fuel cells, metal-air batteries, and water splitting devices. Finally, the magnetic, optical, electrical, and catalytic applications beyond the OER/ORR are also discussed. The future applications of spinels are considered to be closely related to environmental and energy issues, which will be aided by the development of new species with precise preparations and advanced characterizations.

“…As shown in Figure 9C, when 60 wt% of ScSZ with high ionic conductivity is added to the cathode material, the polarization resistance is reduced to 0.06 U$it 2 . By summarizing the above research results, it is found that low ionic conductivity is the main obstacle to spinel oxide as an SOFC cathode material independently, and it is more suitable to combine with other materials to prepare high-performance composite cathodes to take advantage of the high electrons of spinel, such as electrical conductivity and high thermal stability (Zhang et al, 2015).…”

Reversible solid oxide fuel cell (RSOFC) is an energy device that flexibly interchanges between electrical and chemical energy according to people's life and production needs. The development of cell materials affects the stability and cost of the cell, but also restricts its market-oriented development. After decades of research by scientists, a lot of achievements and progress have been made on RSOFC materials. According to the composition and requirements of each component of RSOFC, this article summarizes the research progress based on materials and discusses the merits and demerits of current cell materials in electrochemical performance. According to the efficiency of different materials in solid oxide fuel cell (SOFC mode) and solid oxide electrolyzer (SOEC mode), the challenges encountered by RSOFC in the operation are evaluated, and the future development of RSOFC materials is boldly prospected.

“…Secondly, DRT spectrum possesses higher frequency resolution ( > 5 Hz), but the deconvoluted peaks need an accurate attribution. Recently, complex nonlinear least square (CNLS) combined with the DRT technique can be used to solve the above obstacles successfully [138,[150][151][152][153][154][155][156][157][158][159][160] ( Fig. 17 and Table 2 ).…”
