By conducting an in-depth evaluation into the FJH technique as well as other methods such as chemical vapor deposition, this review seeks to determine which is the most effective method. With high-voltage pulses, FJH can quickly transform waste materials rich in carbon, such as biomass and plastics, into superior quality graphene, while also producing hydrogen gas as a by-product. FJH has been estimated to use around 7.2 kJ/g of energy which is considerably lower than other methods, and it also has a higher scalability and a 90% lower carbon footprint than the classical methods and does not need as many costly catalysts and undergoes less energy demanding processes like electrolysis, which makes it more economically viable. Its usage has been extended to cover energy storage, hydrogen systems, and water purification. With such complex systems, there is bound to be variation in feedstock and defect control which can be solved using advanced AI/ML optimization and better pre-treatments. FJH is one step closer to achieving circular economy goals by turning waste products into materials of value, demonstrating the ability to mass produce hydrogen and graphene in an economical manner to aid in the ideal of a carbon–neutral energy future.</div></div>","PeriodicalId":18283,"journal":{"name":"Materials Science for Energy Technologies","volume":"9 ","pages":"Pages 14-31"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report the in-situ solvothermal synthesis of a compositionally tuneable library of molybdenum sulfoselenide (MoS_2(1-x)Se_2x) nanosheets uniformly anchored on reduced graphene oxide (rGO). The resulting MoS_2(1-x)Se_2x/rGO nanocomposites exhibit significantly enhanced HER activity, with the optimal MoS_0.6Se_1.4/rGO sample achieving a current density of 10 mA cm⁻² at a low overpotential of 118 mV and a Tafel slope of 46.6 mV dec⁻¹ in acidic media. The improved performance is attributed to the synergistic effects of sulfur and selenium incorporation, which modulate hydrogen adsorption energy, enhance orbital hybridization (Mo 4d, S 3p, Se 4p), and facilitate charge separation. Density functional theory (DFT) simulations further reveal that the Janus-type configuration enhances electronic conductivity and reactivity. The rGO substrate provides a conductive framework, promoting efficient charge transport and mechanical stability.

The P3HT is incorporated into rayon fabric via a simple coating process, enabling the fabric to function as a dual mechanical-thermal energy harvesting material.
