Composite structure and enhanced photocatalytic activity in Mn–Co–Ni–O/LaMnO3 microparticles

“…Since decades, many efforts have been made to improve the photocatalytic performances of photocatalysts, such as through textural design, doping, noble metal loading, forming semiconductor composites and exploring novel visible-light-induced photocatalysts [3][4][5][6]. Sun et al reported that compared to non-doped and singly doped photocatalysts, the light absorption performance of Co and Ni co-doped cryptomelane was significantly improved and the degradation rate of phenol was increased, mainly due to the increased specific surface area and the variations in the relative contents of Mn 4+ /Mn 3+ ions [7].…”

Temperature‐dependent electrical transport behavior and structural evolution in hollandite‐type titanium‐based oxide

“…[9][10][11][12][13] In addition to the use of solid matrices for the immobilization of radioactive cesium and anode materials for lithium-ion batteries, [14][15][16][17] hollandite K x Ti 8 O 16 with large (2 × 2) tunnels could accommodate a large number of sodium ions and facilitate Na + diffusion in sodium ion batteries. [21][22][23][24] It is well established that these potential applications are directly determined by the structural and electrical transport properties (especially ionic and electronic conductivities).
