Nanocomposite of N-Doped TiO2 Nanorods and Graphene as an Effective Electrocatalyst for the Oxygen Reduction Reaction

“…Because of the high abundance, N-TiO 2 is one of the most appealing electrocatalysts and appropriate for mass production. 19,20 Recently, the nitrogen-doped (N-doped) carbon materials were reported to have the ability to improve the electron mobility and create favorable catalyst−support interactions, thus greatly promoting the catalyst's activity and stability for ORR. 8,21−25 Among them, graphene, composed of sp 2 hybridized carbon atoms, is very suitable for electric catalyst for ORR due to its high conductivity and outstanding mechanical properties.…”

“…Therefore, the strategies of the doping of TiO 2 with some heteroatoms have been taken. , For instance, developing the doping of TiO 2 with nitrogen (N-TiO 2 ) is an interesting approach. Because of the high abundance, N-TiO 2 is one of the most appealing electrocatalysts and appropriate for mass production. , …”

New Precursor Route Using a Compositionally Flexible Layered Oxide and Nanosheets for Improved Nitrogen Doping and Photocatalytic Activity

“…18−21 Nitrogen-doped metal oxides are also potentially useful for applications in ferroelectrics and oxygen reduction catalysis. 22,23 However, one of the biggest problems of nitrogen introduction into a metal oxide is charge imbalance by the substitution of N 3− for O 2− in the host oxide, which limits the nitrogen concentration in the doped metal oxide host to lower levels and is unfavorable for visible-light absorption. 9,10 Nitridation of oxides is typically conducted by thermal annealing of an oxide precursor under a flow of NH 3 gas at high temperatures (>773 K in most cases).…”
