Recent progress made on the studies of the nature of TiO 2 photocatalysis, in particular whether photocatalytic reactions are driven by separated charges or by energy produced via nonadiabatic exciton decay or nonadiabatic charge recombination, is summarized and discussed in detail. Herein, a novel photoresist enabling the additive fabrication of 3D microstructures using one wavelength and subsequent spatially controlled cleavage of the printed resist using another wavelength is introduced. Microstructures are written upon exposure to nm laser light and subsequent scanning using a laser at nm wavelength allows for the selective removal of the written resist via a photocleavage reaction.

A combination of optical outcoupling and antireflection coatings leads to enhanced visible transmission, while reflecting the NIR back into the cell where it is absorbed. A cationic porous aromatic framework is combined with catalytically active polyoxometalate anions for oxidative catalysis.
