“…Moreover, efficient formation of nanojunctions was achieved by in situ growth of triazine-based conjugated polymer nanolayer onto TiO 2 nanorods arrays. [55] The recombination of photo-generated oxygen vacancies on TiO 2 was suppressed by coated polymers thus efficient photo-electrooxidation at low potential was facilitated, enabling a remarkably low photo-assisted charging potential of 0.80 V/ 1.02 V at 10/20 mA cm À 2 , respectively. In addition to photogenerated carrier strategy, the photo-thermal effect is also a nonnegligible factor.…”

“…Photo‐active polymers like polytrithiophene (pTTh), [52,53] poly(1,4‐di(2‐thienyl))benzene (PDTB), [54] triazine‐based conjugated polymer, [55] and polyaniline nanorod arrays (PANINA) [56] were also exploited to fabricate photo‐assisted cathode for Zn−O 2 batteries. In the discharging process, the p‐type semiconductor pTTh generates photoelectrons and reduces O 2 to intermediate HO 2 − , which is further disproportionated into OH − [53] .…”

To meet the need of high energy density, long durability, safe and cost-efficient energy conversion and storage devices, metal-air batteries like LiÀ O 2 and ZnÀ O 2 batteries have received enormous attention and were subject to exciting development in the past decade. Photo-assisted strategies that enable the effective combination of photo/ electric energy conversion/storage render a new dimension for the conventional metal-air batteries techniques with mere electric energy utilization. Therefore, tremendous research is ongoing in search of more efficient and durable devices with photo-assisted strategies. This review provides an overview of photo-assisted LiÀ O 2 batteries, ZnÀ O 2 batteries, and batteries with various metal/air components. The working mechanism, the basic device architecture and practical performances of various photo-assisted systems are summarized and discussed. Furthermore, certain technical challenges and future opportunities for the photo-assisted metal air batteries are emphasized and discussed in the hope of stimulating further research.

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.

“…In other words, energies of the photogenerated electron and hole (e − /h + ) must be higher than the overpotential of H 2 O/O 2 (0.82 vs. NHE at pH 7) and lower than the overpotential of CO 2 /HCOOH (−0.61 V vs. NHE at pH 7), respectively [ 17 , 18 ]. Performing photo-assisted redox reactions such as CO 2 reduction or water oxidation therefore requires a photocatalyst with an optimum bandgap (at least 2.88 eV) [ 19 ] so as to generate electrons and holes with sufficient energies. Simultaneously, the photocatalyst must be able to absorb large fraction of the solar spectrum even from visible and near IR light absorption (in addition to UV) [ 20 ].…”

TiO2 has aroused considerable attentions as a promising photocatalytic material for decades due to its superior material properties in several fields such as energy and environment. However, the main dilemmas are its wide bandgap (3–3.2 eV), that restricts the light absorption in limited light wavelength region, and the comparatively high charge carrier recombination rate of TiO2, is a hurdle for efficient photocatalytic CO2 conversion. To tackle these problems, lots of researches have been implemented relating to structural and material modification to improve their material, optical, and electrical properties for more efficient photocatalytic CO2 conversion. Recent studies illustrate that crystal facet engineering could broaden the performance of the photocatalysts. As same as for nanostructures which have advantages such as improved light absorption, high surface area, directional charge transport, and efficient charge separation. Moreover, strategies such as doping, junction formation, and hydrogenation have resulted in a promoted photocatalytic performance. Such strategies can markedly change the electronic structure that lies behind the enhancement of the solar spectrum harnessing. In this review, we summarize the works that have been carried out for the enhancement of photocatalytic CO2 conversion by material and structural modification of TiO2 and TiO2-based photocatalytic system. Moreover, we discuss several strategies for synthesis and design of TiO2 photocatalysts for efficient CO2 conversion by nanostructure, structure design of photocatalysts, and material modification.
