<P><B>Abstract</B></P> <P>The conversion of CO<SUB>2</SUB> with H<SUB>2</SUB>O to valuable chemicals and fuels is a new solution to current environmental and energy problems, and the high energy barrier of these reactions can be overcome by the input of solar and electrical energy. However, the reduction efficiencies and selectivities of these reactions are insufficient for practical use, and significant effort and strategy are required to overcome the many obstacles preventing the large-scale application of photocatalytic CO<SUB>2</SUB> reduction. This article reviews recent progress in CO<SUB>2</SUB> reduction using titanium oxide-based materials and various strategic factors for increasing photocatalytic efficiency. This article also highlights non-titanium-oxide catalysts, the photoelectrocatalytic reduction of CO<SUB>2</SUB>, and other recent review articles concerning the recycling of CO<SUB>2</SUB> to value-added carbon compounds.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Conversion of stable CO<SUB>2</SUB> with H<SUB>2</SUB>O to valuable chemicals and fuels. </LI> <LI> Recent progress in CO<SUB>2</SUB> reduction over developed Ti-oxide-based materials. </LI> <LI> Various strategic factors for increasing the photocatalytic efficiency. </LI> <LI> Non Ti-oxide catalysts and photo-electrocatalytic reduction of CO<SUB>2</SUB>. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
