Effect of doping TiO₂ with Mn for electrocatalytic oxidation in acid and alkaline electrolytes

Abstract

Electrochemical oxidation of water and electrolyte ions are sustainable methods for producing energy carriers and valuable chemicals. Among known materials for catalyzing oxidation reactions, titanium dioxide (TiO2) offers excellent electrochemical...

Benefits and Limitations of 226 Substitutions into Li-La-Ti-O Perovskites

“…This is significant, as this shift could allow its integration with the LTO anode in an all-solid-state battery. These changes in the electrochemical stability limits in the case of homogenous microstructure could be due to a change of the Ti–O local environment moving its redox potential . As in the case of heterogeneous microstructure, introduced elements preferentially located on the surface of the grains form an electrochemically inert interphase.…”

“…These changes in the electrochemical stability limits in the case of homogenous microstructure could be due to a change of the Ti−O local environment moving its redox potential. 35 As in the case of heterogeneous microstructure, introduced elements preferentially located on the surface of the grains form an electrochemically inert interphase. Thus, the distribution of substituents can either be evenly distributed throughout the bulk of the material, phase-separated or concentrated at the surface.…”

Biopolymer‐assisted Synthesis of P‐doped TiO2 Nanoparticles for High‐performance Lithium‐ion Batteries: A Comprehensive Study

“…This similarity confirms that there is a comparable local structural modification of the Ti cations in all materials. [51,52] The weak intensity of the Ti preedge peak can be explained by the strong symmetry exhibited by the neighboring Ti cations in these materials. [53,54] The enhancement in the pre-edge peak intensity for the P-doped materials reflects the local structural and electronic structure perturbations caused by P insertion in the TiO 2 lattice.…”

Regulating the coordination environment of a metal–organic framework for an efficient electrocatalytic oxygen evolution reaction

“…[34][35][36][37][38][39] However, in the structure of MOFs, the metal nodes are surrounded by organic linking groups, 40 which limits their catalytic activity and conductivity; 41 thereby, it is vital to construct these structures with a rational design. [42][43][44][45] In terms of macrostructure control, 46 Lou et al typically construct a unique core-shell structure through chemical etching methods and other methods, 47 which could provide a larger catalytic interface area, 48 thereby significantly improving the electrocatalytic performance. 49 Li et al used carbonization to precisely regulate Hofmann-type MOFs into different forms (including nanosheets, nanoflowers, 50 nanotubes and aggregates), which OER catalytic performance far exceeds that of commercial RuO 2 catalysts.…”
