Green hydrogen synthesis has attracted researchers due to energy resource applications. Non‐renewable energy sources have been found to be incapable of meeting energy demands. Therefore, the need of the hour is to introduce an alternative to produce an efficient amount of H2. This review has summarized and investigated hetero‐catalysts and their hydrogen production potential under different light illuminations. Here, the syntheses of various nanoparticles (NPs) and composite semiconductors have been reviewed, and insights into the enhanced ability of noble‐free metal electrocatalysts have been provided. Specific nanomaterials, such as nickel, ruthenium, silver, boron‐doped SnO2, AgVO3, cobalt‐ferrite, and cobalt, dominate in synthesizing durable electrocatalysts. These exhibit Schottky junctions and enhance catalytic behaviour for hydrogen production. Finally, the challenges of the nanoparticle‘s structural and conductive properties and critical solutions are discussed. This review discusses mechanistic insights, interactions, and kinetics that involve a higher H2 synthesis rate.

“…The membranes used for the removal, separation, concentration, analysis, and valorization of hydrogen sulfide are based on ionic polymers [ 37 , 38 ], biopolymers [ 39 , 40 ], organic [ 41 ], or inorganic composites [ 42 ]. Among the ionic polymers, sulfonated polyether ether ketone and sulfonated ethylene–propylene–diene terpolymer (sEPDM) are used [ 43 ], while among biopolymers, chitosan (Chi) is of particular interest, because it covers various membrane separations and spans the membranes for sensors [ 44 , 45 , 46 , 47 , 48 , 49 , 50 ].…”

This paper presents the preparation and characterization of composite membranes based on chitosan (Chi), sulfonated ethylene–propylene–diene terpolymer (sEPDM), and polypropylene (PPy), and designed to capture hydrogen sulfide. The Chi/sEPDM/PPy composite membranes were prepared through controlled evaporation of a toluene dispersion layer of Chi:sEPDM 1;1, w/w, deposited by immersion and under a slight vacuum (100 mmHg) on a PPy hollow fiber support. The composite membranes were characterized morphologically, structurally, and thermally, but also from the point of view of their performance in the process of hydrogen sulfide sequestration in an acidic media solution with metallic ion content (Cu2+, Cd2+, Pb2+, and/or Zn2+). The operational parameters of the pertraction were the pH, pM, matrix gas flow rate, and composition. The results of pertraction from synthetic gases mixture (nitrogen, methane, carbon dioxide) indicated an efficient removal of hydrogen sulfide through the prepared composite membranes, as well as its immobilization as sulfides. The sequestration and the recuperative separation, as sulfides from an acid medium, of the hydrogen sulfide reached up to 96%, decreasing in the order: CuS > PbS > CdS > ZnS.
