- Abstract
As an important regulatory method, the phase engineering strategy is widely used to develop functional materials with desired properties. Herein, we combine a solvothermal method with post‐annealing treatment to controllably synthesize multifunctional MoSe2 flower‐like nanostructures (FNSs) in different crystal phases. Based on the different phases of MoSe2 FNSs, we systematically investigate their performance in lithium‐ion storage, the hydrogen evolution reaction (HER), and the hydrogenation of nitrophenol. The results show that 1T‐MoSe2 FNSs possess superior performance in lithium‐ion batteries, HER, and hydrogenation of PNP compared with 2H‐MoSe2 FNSs. Moreover, density functional theory calculations reveal that 1T‐MoSe2 FNSs exhibits a higher chemisorption energy than that of 2H‐MoSe2 FNSs, which is beneficial for the improvement of the lithium‐ion storage capacity. This work provides an effective way to develop functional materials based on phase engineering.
