“…Compared to lattice substitution, the shorter NTi bond formed by functional substitution tends to form heterojunction with other hybrids sufficiently so that it can prevent recombination of electron and hole pairs. [94,[142][143][144] This mechanism counts a lot when occurs to photocatalytic degradation of wastewater. Ke et al synthesized N-Ti 3 C 2 /TiO 2 to degrade methylene blue at different temperatures, the substitution of O and OH prompts high mobility and narrow bandgap in nanosheet.…”

Heteroatom doping can endow MXenes with various new or improved electromagnetic, physicochemical, optical, and structural properties. This greatly extends the arsenal of MXenes materials and their potential for a spectrum of applications. This article comprehensively and critically discusses the syntheses, properties, and emerging applications of the growing family of heteroatom‐doped MXenes materials. First, the doping strategies, synthesis methods, and theoretical simulations of high‐performance MXenes materials are summarized. In order to achieve high‐performance MXenes materials, the mechanism of atomic element doping from three aspects of lattice optimization, functional substitution, and interface modification is analyzed and summarized, aiming to provide clues for developing new and controllable synthetic routes. The mechanisms underlying their advantageous uses for energy storage, catalysis, sensors, environmental purification and biomedicine are highlighted. Finally, future opportunities and challenges for the study and application of multifunctional high‐performance MXenes are presented. This work could open up new prospects for the development of high‐performance MXenes.

“…[96] Therefore, the topography control of photoelectrodes, in particular, photoelectrodes with porous structures or nanostructures have attracted a lot of attention. [16,97] In compared with traditional semiconductor photoelectrodes, the advantages of nanostructured photoelectrodes are the increase of surface reaction sites and the relatively short transfer distance of carriers, which help to reduce the recombination probability of carriers and improve their PEC properties. Meanwhile, there is enough light absorption to improve the charge collection efficiency.…”

As an emerging solar energy utilization technology, solar redox batteries (SPRBs) combine the superior advantages of photoelectrochemical (PEC) devices and redox batteries and are considered as alternative candidates for large‐scale solar energy capture, conversion, and storage. In this review, a systematic summary from three aspects, including: dye sensitizers, PEC properties, and photoelectronic integrated systems, based on the characteristics of rechargeable batteries and the advantages of photovoltaic technology, is presented. The matching problem of high‐performance dye sensitizers, strategies to improve the performance of photoelectrode PEC, and the working mechanism and structure design of multienergy photoelectronic integrated devices are mainly introduced and analyzed. In particular, the devices and improvement strategies of high‐performance electrode materials are analyzed from the perspective of different photoelectronic integrated devices (liquid‐based and solid‐state‐based). Finally, future perspectives are provided for further improving the performance of SPRBs. This work will open up new prospects for the development of high‐efficiency photoelectronic integrated batteries.

“…When the voltage between the two electrodes is stopped or applied in reverse, the desorption process will begin [ 15 , 16 , 17 , 18 ]. During the process of desorption, acid, alkali, and other reagents can be greatly reduced by post-treatment, thus avoiding secondary pollution [ 19 , 20 ]. In addition, the direct voltage applied between the electrodes just drives the adsorption, and then there are a few other side reactions such as water electrolysis and ion precipitation.…”
