“…Furthermore, a new peak at 27.7° (008) was observed; this was due to the formation of Ti 3 C 2 (OH) 2 , in agreement with results reported by Li et al [ 48 ]. Additionally, the appearance of other, less intense peaks (marked with *) was attributed to the presence of residual Al in the Ti 3 C 2 T x ; this is difficult to remove completely with a 24 h soaking time and leads the formation of AlF 3 [ 49 , 50 , 51 ]. These results suggest that the Ti 3 C 2 T x surfaces were decorated with functional entities of −O and −F after HF treatment, as supported by the EDS spectra [ 52 , 53 ].…”

Three-dimensional mesoporous TiO2 scaffolds of anatase phase possess inherent eximious optical behavior that is beneficial for photoelectrodes used for solar energy conversion applications. In this regard; substantial efforts have been devoted to maximizing the UV and/or visible light absorption efficiency; and suppressing the annihilation of photogenerated charged species; in pristine mesoporous TiO2 structures for improved solar illumination conversion efficiency. This study provides fundamental insights into the use of Mxene functionalized mesoporous TiO2 as a photoelectrode. This novel combination of Mxene functionalized TiO2 electrodes with and without TiCl4 treatment was successfully optimized to intensify the process of photon absorption; charge segregation and photocurrent; resulting in superior photoelectrode performance. The photocurrent measurements of the prepared photoelectrodes were significantly enhanced with increased contents of Mxene due to improved absorption efficiency within the visible region; as verified by UV–Vis absorption spectroscopy. The anatase phase of TiO2 was significantly augmented due to increased contents of Mxene and postdeposition heat treatments; as evidenced by structural analysis. Consequently; an appreciable coverage of well-developed grains on the FTO surface was observed in SEM images. As such; these newly fabricated conductive mesoporous TiO2 photoelectrodes are potential candidates for photoinduced energy conversion and storage applications.

“…In contrast, the D peak occurs only in perturbed sp 2 rings [63]. It is worth noting that the peak at 208 (marked with *) was attributed to the out-of plane vibrations of Ti and C atoms [50,[64][65][66][67]. More prominently, there was an intense peak at around 151 cm −1 .…”

“…Lim et al studied the antifungal properties of MXenes by growing the fungus tricoderma reesei on delaminated Ti 3 C 2 T x nanosheets and found no germination of hyphae and spores even after a culture of 11 days ( Fig. 16 ) [98] . Shamsabadi et al exposed the samples of Bacillus subtilis and Escherichia coli to the colloidal solution of MXene nanosheets and observed the release of bacterial DNA within 3hrs of cultures followed by the bacterial cell dispersion as a result of the strong interaction between the MXene nanosheets and bacterial cell membrane ( Fig.…”

Three-Dimensional mesoporous TiO2 scaffolds of anatase phase possess inherent eximious optical behavior that are beneficial in designing photoelectrodes for solar energy conversion applications. However, substantial efforts have been devoted in maximizing the UV and/or visible light absorption efficiency, and suppressing the annihilation of photogenerated charged species in pristine mesoporous TiO2 structure for improved solar illumination conversion efficiencies. This study provides the fundamental insights into Mxene functionalized mesoporous TiO2 as photoelectrode for the first time. This novel combination of Mxene functionalized TiO2 electrodes with and without TiCl4 treatments have been successfully optimized to intensify the process of photon absorption, charge segregation and photocurrent, resulting in superior photoelectrode performance. The photocurrent measurements of prepared photoelectrodes are significantly enhanced upon increased contents of Mxene due to improved absorption efficiency within the visible region as verified by UV–Vis absorption spectroscopy. Moreover, as evident through structural analysis, the anatase phase of TiO2 is well grown due to increased contents of Mxene and post-deposition heat treatments. Consequently, an appreciable coverage of well-developed grains on FTO surface observed in SEM images. Thereby, the newly fabricated conductive mesoporous TiO2 photoelectrodes are potential candidates for photoinduced energy conversion and storage purposes.
