Modification of Covalent Triazine-Based Frameworks for Photocatalytic Hydrogen Generation

open access: yesPolymers, 2022
The conversion of solar energy and water to hydrogen via semiconductor photocatalysts is one of the efficient strategies to mitigate the energy and environmental crisis. Conjugated polymeric photocatalysts have advantages over their inorganic counterparts. Their molecular structures, band structures, and electronic properties are easily tunable through
