Titanium oxide-Ti3C2 hybrids as sulfur hosts in lithium-sulfur battery: Fast oxidation treatment and enhanced polysulfide adsorption ability

Photocatalytic inactivation of airborne bacteria in a polyurethane foam reactor loaded with a hybrid of MXene and anatase TiO2 exposing {0 0 1} facets

“…A clear peak of Ti-O bond structures suggests the presence of TiO x species in the sample. However, C-Ti peak is hard to be observed in C 1 s spectra because of the high content of TiO 2 [47] , [48] . To further study the effects of MXene on photocatalytic activity, PL spectra of the TiO 2 /MXene and pure TiO 2 are tested and shown in Fig.…”

Host Materials Anchoring Polysulfides in Li–S Batteries Reviewed

“…various conductive carbons and inorganic compounds have been integrated with Mxenes in order to achieve enhanced capacity and increased cycle life. [337][338][339][340][341] The Wang group developed a series of 3D MXene/carbon hybrid structures to further improve Li-S batteries. [331,342,343] For example, they reported a hybrid 3D Ti 3 C 2 T x @mesoporous carbon architecture (Ti 3 C 2 T x @Meso-C) as sulfur host material.…”

The Electrostatic Attraction and Catalytic Effect Enabled by Ionic–Covalent Organic Nanosheets on MXene for Separator Modification of Lithium–Sulfur Batteries

“…[27][28][29][30] However, one insurmountable barrier in MXene nanosheets is the tendency to restack because of the van der Waals attraction and hydrogen bonding interactions, resulting in substantial loss of specific surface area and the inaccessibility toward high concentration of polysulfides. [31] One of the effective solutions is the integration of MXenes with porous materials to form composites. 2D covalent organic frameworks (COFs) are one type of appealing porous materials composed of strong covalent bonds and periodic building units.…”
