A supporting body of diatomite-based porous ceramics was prepared by a solid-phase sintering process and low-temperature calcination process. nanoTiO2 membrane was loaded on the carrier by the hydrolysis precipitation method and using TiCl4 as the precursor. The influences of various parameters such as the initial concentration of malachite green, the amount of composites, and the initial pH had been investigated. Under the same test conditions, the decolorizing rate of malachite green was higher when the initial concentration was 6 mg/L, the composites dosage was 5 g/L, and the initial pH was 8 respectively. The influence mechanism of the initial concentration of malachite green, the amount of composites, and the initial pH for malachite green was discussed.

Spinel LiMn2O4 is of value for Li-ion batteries. However, the capacity decay due to the Jahn-teller effect still must be solved. Li-rich materials depress the Jahn-Teller effect by increasing the Li-ion content and decreasing the Mn3+ content simultaneously. In this paper, rod-like Li-rich spinel Li1+xMn2−xO4 was prepared by a hydrothermal synthesis-solid phase calcination method. The electrochemical performance test showed that the Li-rich materials had higher charge-discharge capacity and cycle performance, and the Li1.06Mn1.94O4 material had the best electrochemical performance. The specific discharge capacity reached 118 mAh/g at 0.5 °C and the capacity retentions were 95.69% and 90.72%, respectively, at 25 °C and 55 °C after 100 cycles. The discharge capacities of Li1+xMn2−xO4 were better than pure LiMn2O4 under high discharge rates.
