“…A two-compartment cell separated with a proton-conducting polymer membrane based on the composite membrane for photocatalytic H 2 generation under sunlight without any electrical or chemical bias was reported by Marschall et al This composite polymer membrane that acted as both compartment separator and support for coated electrodes and photocatalyst was prepared using sulfonated polyether sulfone and sulfonated mesoporous Si-MCM-41 nanoparticles. In another work, a photoanode made of ZnO/Cu 2 S-loaded PVDF polymer membrane was used for solar water splitting application . The PVDF/Ag/ZnO/Cu 2 S photoanode was reported to generate a photocurrent density of 0.62 mAcm –2 in the −0.2 to 0.4 V vs Ag/AgCl potential window.…”

Keeping global warming at 2 degrees and below as stated in the "Paris Climate Agreement" and minimizing emissions can only be achieved by establishing a hydrogen (H 2 ) ecosystem. Therefore, H 2 technologies stand out in terms of accomplishing zero net emissions. Although H 2 is the most abundant element in the known universe, molecular H 2 is very rare in nature and must be produced. In H 2 production, reforming natural gas and renewable hydrogen processes using electrolyzers comes to the fore. The key to all these technologies is to enhance production speed, performance, and system lifetime. At this point, composite membranes used in both processes come to the fore. This review article summarizes composite membrane technologies used in methane, ethanol, and biomass steam reforming processes, proton exchange membranes, alkaline water electrolysis, and hybrid sulfur cycle. In addition to these common H 2 production technologies at large quantities, the innovative systems developed with solar energy integration for H 2 generation were linked to composite membrane utilization. This study aimed to draw attention to the importance of composite membranes in H 2 production. It aims to prepare a guiding summary for those working on membranes by combining the latest and cutting-edge studies on this subject.

“…[3][4][5] Photocatalysis is a sustainable, cost-effective, and environmentally friendly technology for producing H 2 . [6][7][8][9] Titanium dioxide (TiO 2 ) is a low-toxicity, highly stable, and inexpensive UV-responsive semiconductor that has been widely researched for the objective of achieving transcendent photocatalytic performance. Doping TiO 2 with metals or non-metals reduces the TiO 2 energy gap and enhances the utilization of doped-TiO 2 photocatalysts exposed to sunlight.…”

The influence of the polymerization temperature upon the bulk‐structure‐doped conductive polymer polyaniline (emeraldine‐salt, PANI) on the semiconducting, optical, and electrical properties of the photocatalyst is investigated. When the B‐PANI polymerization temperature increases from 5 to 60 °C, the crystallinity and conductivity of Pt/N‐TiO2/B‐PANI (PNT/B‐PANI) decreases. To rectify the problems of recycling convenience and secondary pollution, this study combines a photocatalyst and a porous polystyrene film for sustainable hydrogen production. The photocatalytic performance of the polystyrene/PNT/B‐PANI‐5 (PS/PNT/B‐PANI‐5) photocatalyst film (27 047 μmol h−1 g−1) under simulated sunlight irradiation is enhanced by a factor of up to 1.6 compared to that of PS/PNT. Therefore, the PS/PNT/B‐PANI photocatalyst film is a visible‐light photocatalyst which is a promising candidate for enhancing photocatalytic recycling convenience.
