Abstract
Summary
A photochemical reduction of CO2 to CO or formic acid was shown using the bipyridine-based catalysts [Re(bpy)(CO)3(MeCN)][PF6], Ru(dtBubpy)(CO)2Cl2 or -missing link parameter-in combination with the ruthenium-based photosensitizer [Ru(dmb)3][PF6]2 or Ru(bpy)3. Turnover numbers (TONs) of up to 157 and selectivities up to 85% for formate were reached in DMF. The experiments were conducted under visible-light irradiation (λ = 480 nm) using TEOA and BNAH as sacrificial electron donors (see section SEDs below).
