Abstract

We have constructed a robust β-helical nanotube from the component proteins of bacteriophage T4 and modified this nanotube with Ru^II(bpy)₃ and Re^I(bpy)(CO)₃Cl complexes. The photocatalytic system arranged on the tube catalyzes the reduction of CO₂ with higher reactivity than that of the mixture of the monomeric forms.
