Abstract：

Photocatalytic　CO2　reduction　over　Ru(ii)-complex/Ag/polymeric　carbon　nitride　(PCN)　was　studied　with　respect　to　light　intensity　and　the　type　of　Ru(ii)　complex.　In　experiments　using　two　different　Ru(ii)　complex　cocatalysts,　the　reduction　potential　of　the　Ru　complex　was　found　to　balance　efficient　CO2　reduction　on　the　Ru　complex　with　electron　transfer　from　Ag/PCN.　This　balance　avoided　the　formation　of　H2　as　a　byproduct,　minimized　charge　accumulation　in　Ag/PCN,　and　maximized　the　apparent　quantum　yield　for　CO2-to-HCOOH　conversion.
