“…Additionally the broad Ti 2p peak suggests the presence of titanium with lower oxidation states, and the line slightly became broad with added calcium [34], and the peak shifted with the Ca loading to high binding energy, which meaning more oxidized state. Generally the O 1s binding energies are located in the 530.9-536.2 eV regions [35]. In this study, the binding energy at 530.9 eV and 533.7 eV can be assigned to TiO 2 and SiO 2 , respectively.…”

“…CH 4 was not produced over pure Ca(5.0 wt.%)/SiMCM-41, but the level of production increased gradually with increasing Ti-content. On the other hand, in Ti 35 Si 65 MCM-41 sample without Ca ingredient loading, the methane generation did not significantly increase compared to the Ca loaded Ti35 Si 65 MCM-41 sample. This is an evidence that the Ca ingredient affects the photoreaction of CO 2 perhaps increasing the amount of adsorption of carbon dioxide on the calcium surfaces.…”

“…When the light was turned on, a rapid increase in the photoreduction current was observed, and the photocurrent then turned to a steady state after a few seconds, as light off, the photocurrent dropped to nearly zero instantaneously [43]. When the light was turned on, the maximum photocurrent was obtained for the Ca(10.0 wt.%)/Ti 35 Si 65 MCM-41 film with 137 nA cm −2 , which is 9.6% higher than that achieved on Ti 35 Si 65 MCM-41 film (113 nA cm −2 ). Additionally there are no Scheme 1.…”

“…The lowest pore volume has the largest average pore diameter because of the increasing nonstructural porosity consisting of some irregular cavities that permeate the entire bulk and give rise to secondary porosity. X-ray photoelectron spectroscopy (XPS) analysis for two samples, Ti 35 [35]. These species are related to photocatalytic activity on Si O Ti systems, perhaps acting as adsorption sites of the reactants.…”

The applications of lithium metal anode are limited by uncontrollable lithium dendrite growth and infinite volume changes during cycling. These fundamental issues are exacerbated at high cycling current densities and capacities. Herein, a mechanically stable and resilient lithium metal host is fabricated by covalently cross‐linking a highly‐conductive and lithiophilic MXene/silver nanowire scaffold through a silylation reaction between MXene nanosheets and polysiloxane. Compared with the control sample (an MXene scaffold assembled by weak van der Waals forces), the covalently cross‐linked MXene scaffold displays excellent mechanical strength and resilience, which is conducive to buffer the large internal stress fluctuations generated during rapid and deep lithium plating‐stripping and guaranteed that the integrated framework structure is maintained during long‐term charging‐discharging cycles. When used in a symmetric cell, the lithium composite anode based on the covalently cross‐linked MXene host affords an unprecedented cyclic lithium plating‐stripping stability of a record‐high 3000 h lifespan at an ultrahigh current density (20 mA cm−2) and areal capacity (10 mAh cm−2). When this composite anode is coupled with a LiNi0.5Co0.2Mn0.3O2 cathode, the full cell delivers an ultrahigh rate of 10 C for up to 1000 cycles, with an average capacity decay of 0.043% per cycle and a stable Coulombic efficiency of 98.7%.
