Summary: This study investigates the exfoliation reaction of H2O2-modified layered titanate H1.07Ti1.73O4 (H2O2-HTO) and its applications in the synthesis of NiTiO3/TiO2 nanocomposites as anode materials for lithium-ion batteries (LIBs). It is found that H2O2 enhances the ion-exchange capacity and exfoliation reaction kinetics of H2O2-HTO. The nanosheets of H2O2-HTO can be assembled into sandwich layered structures and transformed into polycrystalline or mesocrystalline NiTiO3/TiO2 nanocomposites with different morphologies and properties. The NiTiO3 nanocrystals in the mesocrystalline nanocomposite show a much larger capacity due to the mesocrystalline effect.

Summary: In the catalytic process of semiconductors, the rapid recombination of electron-holes greatly reduces the catalytic activity. A low-defect reduced hydroxylated graphene (RGOH) was used as a carrier material to prepare TiO2/reduced hydroxylated graphene (T/RGOH) nanocomposite photocatalyst, which showed a higher degradation efficiency for methylene blue compared to pure TiO2 and TiO2/reduced graphene oxide (T/RGO) nanocomposite photocatalysts. The enhanced performance was attributed to the higher electrical conductivity of RGOH and the existence of Ti-O-C bonds in the T/RGOH, which improved electron-hole separation and prevented rapid recombination.

Summary: Nickel titanate is a yellow-brown pigment with a crystal structure similar to corundum and hematite. It has been found that nickel titanate can change its color with temperature, exhibiting thermochromic properties. The powders were synthesized using a modified Pechini method and then subjected to calcination at 700 degrees C. The thermochromic behavior in the temperature range of 20 degrees C to 400 degrees C was studied by determining the colorimetric L*a*b* parameters. The hue continuously shifts from yellow-brown to red-brown, with L*a*b* parameters changing from 60.4/19.2/58.5 to 42.9/30.5/43.1. It was also observed that the transparency window shifted from 550-650 nm at room temperature to 575-650 nm at 400 degrees C, explaining the color change. Additionally, the effects of Cu or Co doping on the optical and thermochromic properties of nickel titanate were investigated.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.
