The heat is on: Direct coupling of thermo- and photocatalysis over Au−Ru/TiO₂ leads to 15 times higher activity (T=358 K; ca. 99 % CH₄ selectivity) in the conversion of CO₂–H₂O into fuels than purely photocatalytic water splitting, which is ascribed to the promoting effect of thermocatalytic hydrogenation of CO₂ with hydrogen atoms generated in situ by photocatalytic water splitting.

将热催化和光催化直接耦合以将CO2-H2O转化为燃料

热量不断释放：在Au-Ru / TiO _2上进行热催化和光催化的直接偶联可将CO ₂ -H ₂ O转化为活性的活性提高15倍（T = 358 K；约99％CH ₄选择性）。与单纯的光催化水分解相比，它能提供更多的燃料，这归因于光催化水分解在原位产生的氢原子对CO ₂的热催化加氢的促进作用。
