High surface areas, dual active sites, a variety of pore architectures and tunable functionalities are some of the distinctive structural features of CPs that cooperatively enhance light harvesting, enable photoinduced charge carrier separation and transport, and promote efficient interaction between catalytic sites and water molecules.
