“…DFT calculations also predict that the interaction of CO 2 with {010} was stronger than its interactions with {101} or {001} 125. Apart from TiO 2 , other transition metal oxides such as WO 3 and ZrO 2 as well as oxysalts such as titanates (ATiO 3 , A = Na, Sr, Ca, or Pb), tantalates (ATaO 3 , A = Li, Na, or K), niobates (ANbO 3 , A = Na, K), tungstate (Bi 2 WO 6 ), and vanadates (BiVO 4 , InVO 4 , Na 2 V 6 O 16 · x H 2 O) have also been explored in photocatalytic CO 2 reduction 126, 127, 128, 129, 130, 131, 132.

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.

“…Therefore, many efforts have been made to search for the visible-light-driven photocatalysts. One typical strategy is to exploit new single-phase visible-light-driven photocatalysts (e.g., CdS [60,63,108], C 3 N 4 [69,109,110], WO 3 [111,112], CaFe 2 O 4 [113,114], LaCoO 3 [115], BiVO 4 [116,117], Bi 2 WO 4 [118,119], Fe 2 V 4 O 13 [120] and InTaO 4 [121][122][123][124]), which have proven to be active for photocatalytic reduction of CO 2 in visible region. The other typical strategy is to make the wide band gap semiconductors active in visible region through a suitable modification.…”

“…In addition, ZnGa 2 O 4 nanocube with the exposed (100) or (110) facets [202,203], Bi 2 WO 6 square nanoplates with the exposed (001) surface [118], BiOCl nanoplates with oxygen vacancies [204], nanoplate-textured Zn 2 SnO 4 with the exposed (100) surface [205] and WO 3 nanosheets with the exposed (001) surface [111] were successively reported. These nanoplate/nanosheet photocatalysts exhibit enhanced performance for photocatalytic reduction of CO 2 into CH 4 in the presence of water vapor due to the improved separation of photo-generated electron and hole pairs .…”

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...

“…Therefore, the photocatalytic hydrogenation of CO2 upon semiconductor powders has received much attention [9][10][11][44][45][46][47][48][49][50][51][52][53][54][55][56]. Among the earliest studies on the photocatalytic hydrogenation of CO2, Inoue et al examined a wide range of semiconductors (WO3, TiO2, ZnO, CdS, GaP, and SiC in 200 -400 mesh) in aqueous solution [44].…”
