“…In a recent study performed by Weiming Zhou et al, an inorganic composite membrane constructed by a 2D lamellar membrane based on the semiconductor BiOCl nanosheets was studied for photocatalytic H 2 generation. 157 A composite prepared from BiOCl and cellulose nanofibers (CNFs), carbon nanotubes (CNTs), and photocatalytic H 2 generation rates were reported as 25.42 μmol·g –1 ·h –1 for BiOCl-CNF@CNT nanocomposite lamellar membrane ( Figure 5 a). In another work, ZnSe, carbon membrane, and TiO 2 nanotube arrays were constructed to get the carbon membrane bridged ZnSe and TiO 2 composite ( Figure 5 b).…”

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.

Defective layered bismuth oxychloride (BiOCl) exhibits excellent photocatalytic activities in water purification and environmental remediation. Herein, in situ single‐molecule fluorescence microscopy is used to spatially resolve the photocatalytic heterogeneity and quantify the photoredox activities on individual structural features of BiOCl. The BiOCl nanoplates with respective dominant {001} and {010} facets (BOC‐001 and BOC‐010) are fabricated through tuning the pH of the solution. The corner position of BOC‐001 exhibits the highest photo‐oxidation turnover rate of 262.7 ± 30.8 s−1 µm−2, which is 2.1 and 65.7 times of those of edges and basal planes, respectively. A similar trend is also observed on BOC‐010, which can be explained by the heterogeneous distribution of defects at each structure. Besides, BOC‐001 shows a higher photoredox activity than BOC‐010 at corners and edges. This can be attributed to the superior charge separation ability, active high‐index facets of BOC‐001, and its co‐exposure of anisotropic facets steering the charge flow. Therefore, this work provides an effective strategy to understand the facet‐dependent properties of single‐crystalline materials at nanometer resolution. The quantification of site‐specific photoredox activities on BiOCl nanoplates sheds more light on the design and optimization of 2D materials at the single‐molecule level.
