Witryna24 lis 2024 · Aerogels have interconnected networks and preeminent pore structures. When used as the catalysts for oxygen reduction reaction (ORR), they can facilitate the mass transfer and expose more active sites. Here, we synthesized the Fe-doped titanium oxide-based aerogels (TA/Fes) by the sol–gel method combined with thermal … WitrynaRutile-type titanium oxide (TiO2) is a resource-rich and inexpensive material with a one-dimensional ion-diffusion path along the c-axis. However, it has received no attention as an anode material for Na-ion batteries because of its low electronic conductivity and limited ion diffusion in the ab-plane direction. We have revealed for the first time the …
