“…In the last few decades, a rapid increase in the consumption of fossil-fuel-derived energy has not only affected the environment to the maximum extent but also sparked a devastating crisis in the energy generation cycle, which is an extreme alert for the burgeoning human race. The quest for alternative, sustainable, and clean sources of energy that can replace the diminishing nonrenewable energy resources needs to be addressed with utmost priority. − …”

Photocatalytic water splitting, CO2 reduction, and pollutant degradation have emerged as promising strategies to remedy the existing environmental and energy crises. However, grafting of expensive and less abundant noble-metal cocatalysts on photocatalyst materials is a mandatory practice to achieve enhanced photocatalytic performance owing to the ability of the cocatalysts to extract electrons efficiently from the photocatalyst and enable rapid/enhanced catalytic reaction. Hence, developing highly efficient, inexpensive, and noble-metal-free cocatalysts composed of earth-abundant elements is considered as a noteworthy step toward considering photocatalysis as a more economical strategy. Recently, MXenes (two-dimensional (2D) transition-metal carbides, nitrides, and carbonitrides) have shown huge potential as alternatives for noble-metal cocatalysts. MXenes have several excellent properties, including atomically thin 2D morphology, metallic electrical conductivity, hydrophilic surface, and high specific surface area. In addition, they exhibit Gibbs free energy of intermediate H atom adsorption as close to zero and less than that of a commercial Pt-based cocatalyst, a Fermi level position above the H2 generation potential, and an excellent ability to capture and activate CO2 molecules. Therefore, there is a growing interest in MXene-based photocatalyst materials for various photocatalytic events. In this review, we focus on the recent advances in the synthesis of MXenes with 2D and 0D morphologies, the stability of MXenes, and MXene-based photocatalysts for H2 evolution, CO2 reduction, and pollutant degradation. The existing challenges and the possible future directions to enhance the photocatalytic performance of MXene-based photocatalysts are also discussed.

“…7 It is urgent for us to further accelerate the research with regard to the stable operation of LCO at high voltage, which is the momentous basis for enhancing the competitiveness of LCO in the high-demand battery market. 8 Various strategies have been explored to circumvent these drawbacks, such as elemental doping, 9 surface coating, [10][11][12] morphology design, 13 and employing separators, 14 electrolytes, 15 and the corresponding additives. 16 Although elemental doping shows a surprising result, the improvement is limited, especially at a higher voltage (>4.45 V) and under more extreme operating conditions.…”

“…7 However, the lack of polar groups on the polyolefin's surface makes the separator difficult to completely wet with the electrolyte, which results in blocking the transport and diffusion of lithium ions inside the polyolefin separator. 8,9 Moreover, the thermal contraction of the separator becomes serious at high temperatures, which not only fails to achieve insulation, but even causes an internal short circuit of the battery. 10 Therefore, it is difficult for pure polyolefin separators to meet the demand of power batteries.…”
