The phenomenon of electron recombination is particularly detrimental to photocatalytic hydrogen evolution efficiency. When a photocatalyst absorbs light, it generates electron-hole pairs ; however, if these charge carriers recombine before they can be utilized in the HER process, the catalytic efficiency is significantly reduced. Electron recombination occurs when the excited electrons and holes return to their original states, releasing energy in the form of heat or light instead of driving the desired reaction. In organic photocatalysts, poor charge separation and slow electron transfer rates exacerbate this issue . Additionally, the lack of efficient electron transport networks in organic materials can hinder the migration of charge carriers to the catalytic sites, increasing the likelihood of recombination. Tackling this challenge requires the development of advanced materials that can not only promote effective charge separation but also facilitate rapid charge transport to the reaction sites, thereby improving the efficiency of HER processes.
