Hydrolysis or water splitting has been recognized as efficient comparative to fossil fuels because of the high energy density carrier and environmentally friendly nature. Many hydrolytic materials have been explored but still facing challenges such as sluggish hydrogen kinetics, formation of surface passivation layers and low yield. Hydrolysis of metals has been thoroughly investigated for the production of hydrogen due to its versatile properties, like safe storage and effective supply of hydrogen in a sustainable manner. A variety of methods have been proposed to improve the efficiency, including alloying, changing aqueous solutions, structure of material, and composite formation, however, there is a pressing need to create affordable and environment-friendly materials which is lacking. The current review provides a comprehensive evaluation of recent research contributions of carbonaceous materials for hydrogen generation, particularly their potential as a catalyst for Mg-based materials hydrolysis. Carbon-based materials have abundance, cost-effectiveness, chemical stability, attractive band structure, and easy preparation methods making them an ideal catalytic candidate for metal hydrolysis. Graphene, graphene oxide, carbon nanotubes, carbide and carbon-based composite are employed as catalysts for Mg-based materials hydrolysis. The goal of this study is to inspire readers to research the environmentally friendly production of hydrogen using carbon-based materials.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"219 ","pages":"Article 115864"},"PeriodicalIF":16.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis is based on a case study of an industrial plant in Iran, considering both the feed-in tariff and time-of-use scheme. A three-stage approach is employed, utilizing a combination of MATLAB software, PVsyst, and HOMER Grid. To account for load and renewable energy sources uncertainties, scenario-based and backward methods are employed to generate a manageable set of relevant scenarios. Given the project’s 25-year lifespan, a sensitivity analysis is conducted to assess the impact of varying annual grid electricity tariff increases. In the first step, using MATLAB, scenarios are created to account for uncertainty. In the second stage, based on the data from the previous stage, the design and technical analysis of the PV system evaluated using PVsyst software. Finally, in the third stage, the economic analysis of the proposed system is performed in HOMER grid software, using the outputs from the previous two stages. The simulated PV system achieved an average performance ratio of 80.4%. Additionally, the system has the potential to reduce CO2 emissions by 188,611.595 tons over its lifetime. Furthermore, the economic analysis, incorporating a comprehensive sensitivity analysis of key factors such as grid tariff increases, PV degradation, and inflation rates, indicates that the proposed system’s net present cost becomes lower than that of relying solely on grid electricity if the annual grid tariff increase exceeds 10%.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"219 ","pages":"Article 115808"},"PeriodicalIF":16.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using state-of-the-art <i>ab initio</i> calculations and excited-state dynamics simulations, we explore the photodissociation pathways of iodobenzene (PhI) and bromobenzene (PhBr). For PhI, two dissociation pathways, direct and indirect modes, are identified, consistent with gas-phase experiments. In contrast, photodissociation of PhBr occurs only after overcoming the energy barrier between bound and repulsive states, which requires activation of specific vibrational modes, particularly those associated with boat-like out-of-plane motion. While previous studies have suggested that SOC primarily accelerates intersystem crossing and photodissociation in heavier halogens, our results show that, in addition to SOC, the activation of specific vibrational modes also plays a crucial role in the dissociation process. These findings enhance our understanding of how SOC influences excited-state dynamics, providing insight into controlling photochemical reactivity in halogenated organic compounds.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"206 1","pages":""},"PeriodicalIF":6.475,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
