Polymer photocatalysts are a synthetically diverse class of materials that can be used for the production of solar fuels such as H 2 , but the underlying mechanisms by which they operate are poorly understood. Time-resolved vibrational spectroscopy provides a powerful structure-specific probe of photogenerated species. Here we report the use of time-resolved resonance Raman (TR 3 ) spectroscopy to study the formation of polaron pairs and electron polarons in one of the most active linear polymer photocatalysts for H 2 production, poly(dibenzo-[b,d]thiophene sulfone), P10. We identify that polaron-pair formation prior to thermalization of the initially generated excited states is an important pathway for the generation of long-lived photoelectrons.

Manganese carbonyl complexes have been studied extensively in solution as low cost, selective electrocatalysts with a low overpotential for CO2 reduction but experiments are typically at low current densities. In...

Through the co-polymerisation of dicyandiamide and barbituric acid precursors, a series of visible light active carbon nitride photocatalysts has been prepared and characterized, and their photocatalytic activity has been evaluated....
