“…The same research group also showed that when coupled with the oxidation of acetylacetone by photogenerated holes from its valence band, photocatalytic CO 2 reduction on ZnS would lead to the formation of carboxylic acids 138. In addition to above compounds, other sulfides and solid solutions were also investigated 139, 140, 141, 142…”

Increasing CO2 concentration in the atmosphere is believed to have a profound impact on the global climate. To reverse the impact would necessitate not only curbing the reliance on fossil fuels but also developing effective strategies capture and utilize CO2 from the atmosphere. Among several available strategies, CO2 reduction via the electrochemical or photochemical approach is particularly attractive since the required energy input can be potentially supplied from renewable sources such as solar energy. In this Review, an overview on these two different but inherently connected approaches is provided and recent progress on the development, engineering, and understanding of CO2 reduction electrocatalysts and photocatalysts is summarized. First, the basic principles that govern electrocatalytic or photocatalytic CO2 reduction and their important performance metrics are discussed. Then, a detailed discussion on different CO2 reduction electrocatalysts and photocatalysts as well as their generally designing strategies is provided. At the end of this Review, perspectives on the opportunities and possible directions for future development of this field are presented.

“…The significantly enhanced activity can be attributed to the improved surface area and high CO 2 adsorption capacity. Bi 2 S 3 microspheres also showed the higher activity for photocatalytic reduction of CO 2 to methyl formate in methanol due to their special hierarchical structure, good permeability and high light-harvesting capacity, as compared with Bi 2 S 3 NPs [94].…”

“…Meanwhile, Frei and coworkers [92,93] demonstrated that formic acid is the primary 2-electron reduction product of CO 2 at the excited Ti centers of Ti silicalite molecular sieve using methanol as electron donor, while CO is the single-photon, 2-electron-transfer reduction product of CO 2 at framework Ti centers with H 2 O acting as an electron donor. Moreover, methyl formate was also mainly produced for photocatalytic reduction of CO 2 over some other photocatalysts (such as Bi 2 S 3 [94], CuO-TiO 2 [95], Ni-doped ZnS [96] and Ag Loaded SrTiO 3 [49]) in methanol solution. Therefore, the two-electron, two-proton reaction steps from methanol or formic acid to hydrocarbons on most semiconductors seem to be impossible in many systems.…”

“…Thus, the 3D hierarchical semiconductor architectures have been widely applied in the CO 2 photoreduction due to their increased specific areas and adsorption of CO 2 , as well as improved light harvesting and interfacial charge separation [94,119,207]. For example, Bi 2 WO 6 hierarchical microspheres with hollow interiors synthesized via a facile anion exchange method display an excellent photoactivity for reduction of CO 2 to methanol (32.6 μmol g −1 ), which is 25.5 times higher than that of Bi 2 WO 6 prepared by solid state reaction (1.28 μmol g −1 ) under the same conditions [119].…”

The shortage of fossil fuels and the disastrous pollution of the environment have led to an increasing interest in artificial photosynthesis. The photocatalytic conversion of CO 2 into solar fuel is believed to be one of the best methods to overcome both the energy crisis and environmental problems. It is of significant importance to efficiently manage the surface reactions and the photo-generated charge carriers to maximize the activity and selectivity of semiconductor photocatalysts for photoconversion of CO 2 and H 2 O to solar fuel. To date, a variety of strategies have been developed to boost their photocatalytic activity and selectivity for CO 2 photoreduction. Based on the analysis of limited factors in improving the photocatalytic efficiency and selectivity, this review attempts to summarize these strategies and their corresponding design principles, including increased visible-light excitation, promoted charge transfer and separation, enhanced adsorption and activation of CO 2 , accelerated CO 2 reduction kinetics and suppressed undesirable reaction. Furthermore, we not only provide a summary of the recent progress in the rational design and fabrication of highly active and selective photocatalysts for the photoreduction of CO 2 , but also offer some fundamental insights into designing highly efficient photocatalysts for water splitting or pollutant degradation. INTRODUCTIONThe shortage of the energy supply and the problem of disastrous environmental pollution have been recognized as two main challenges in the near future [1]. It is a better way to efficiently and inexpensively convert solar energy into chemical fuels by developing an artificial photosynthetic (APS) system because solar fuels are high density energy carriers with long-term storage capacity. The most important and challenging reactions in APS-the photocatalytic water splitting into H 2 and O 2 (water reduction and oxidation) [2][3][4] and photoreduction of CO 2 to solar fuel, such as CH 4 and CH 3 OH [5,6] have been extensively studied since the photocatalytic water splitting on TiO 2 electrodes was discovered by Honda and Fujishima in 1972 [7]. The photocatalytic reduction of CO 2 by means of solar energy has attracted growing attention in the recent years, which 1 State Key Laboratory of Advanced Technology for Material Synthesis and Processing, Wuhan University of Technology, Wuhan 430070, China 2 College of Science, South China Agricultural University, Guangzhou 510642, China 3 Department of Physics, Faculty of Science, King Abdulaziz University, Jeddah 21589, Saudi Arabia * Corresponding author (email: jiaguoyu@yahoo.com) is also believed to be one of the best methods to overcome both global warming and energy crisis [8]. However, it is also generally thought that photocatalytic CO 2 reduction is a more complex and difficult process than H 2 production due to preferential H 2 production and low selectivity for the carbon species produced [9,10]. The progress achieved in the photoreduction of CO 2 is still far behind that in wate...

“…In this regard, alternative anode materials with higher capacity have been developed, such as Si, 4 Sn, 5 metal oxides, 6 and metal sulfides. 7 As a typical metal sulfide, Bi 2 S 3 has been widely used in many fields, such as optics, 8,9 photoelectricity, 10,11 photocatalysis, 12,13 and biology. 14,15 Due to its lamellar structure, Bi 2 S 3 is also investigated as an ideal host for hydrogen 16,17 and lithium storage.…”

Anode materials with high capacity are urgently required to substitute graphite. The theoretical gravimetric and volumetric capacities of Bi 2 S 3 are much higher than those of graphite, but the cycling performance of Bi 2 S 3 is poor due to its large volumetric expansion. Amorphous SiO 2 is mechanically rigid, which can buffer the volume change. A novel Bi 2 S 3 @SiO 2 core-shell microwire is firstly designed and synthesized in this work. The composite exhibits excellent electrochemical performances. The discharge capacity is 379 mA h g −1 after 4000 cycles at the current density of 1 A g −1 .
