“…Importantly, the oxidation of obtained products was prevented via the anode in separated solution. In addition, in Izumi's group, the photocatalytic water oxidation and photocatalytic reduction of CO 2 were successfully integrated in reverse photofuel cells [281,359]. In this new reactor, the oxidation of products from photoreduction of CO 2 can be avoided due to the separate water oxidation and CO 2 reduction, thus leading to an enhanced activity for photoreduction of CO 2 [18].…”

“…More importantly, it also can inhibit the reoxidation of products owing to avoiding direct contact of products and TiO 2 [276]. In addition to MgO, ZrO 2 [278], Ga 2 O 3 [279] and layered double hydroxides [280][281][282] also have great potentials to function as modifiers to enhance the activities for photocatalytic reduction of CO 2 over semiconductor photocatalysts.…”

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...

-Photocatalytic conversion of CO 2 into fuels is an attractive option in terms of both reducing the increased concentration of atmospheric CO 2 as well as generating renewable hydrocarbon fuels. It is necessary to investigate good catalysts for CO 2 conversion and to clarify the mechanism irradiated by natural light. Layered Double Hydroxides (LDH) have been attracting attention for CO 2 photoreduction with the expectation of sorption capacity for CO 2 in the layered space and tunable semiconductor properties as a result of the choice of metal cations. This study first clarifies the effects of Cu doping to LDH comprising Zn and Al or Ga. Cu could be incorporated in the cationic layers of LDH as divalent metal cations and/or interlayer anions as Cu (OH) Résumé -Conversion photocatalytique du dioxyde de carbone par des hydroxydes doubles lamellaires de Zn-Cu-Ga promus par la phtalocyanine de Cu : nécessité du contact entre le Cu et le réactif gazeux pour la synthèse du méthanol -La conversion photocatalytique de CO 2 est une option attractive pour limiter la concentration du CO 2 atmosphérique quand elle a pour objectif la production de produits hydrocarbonés utilisés comme carburants renouvelables.
