The sulfur–iodine cycle has emerged as a cost-effective global process with massive hydrogen production potentials. However, all sulfur-based thermochemical cycles involve sulfuric acid decomposition reaction, which is highly corrosive and energy intensive. The activation energy of this reaction can be reduced using catalysts that decrease the onset temperature of the reaction. Renewable heat sources such as solar and waste nuclear heat demand high stability to operate within a wide temperature window (650°C–900°C). Several metal/metal oxide systems based on noble and transition metals have been investigated over the last twenty years. In the literature, supported Pt-based catalysts are regarded as the prime choice for stable operations. However, during catalytic operations, noble metals are degraded owing to sintering, oxidation, leaching, and other processes. Transition metal oxides such as Fe, Cu, Cr, and Ni exhibit promising catalytic activity at high temperatures; however, at low temperatures (>600°C), their activation is reduced owing to poisoning and the formation of stable sulfate species. The catalytic activity of transition metal oxides is determined by the decomposition temperature of its corresponding metal sulfate; thus, the metal sulfate formation is considered as the rate-limiting step. Herein, the catalytic systems studied over the last decade are summarized, and recommendations for designing robust catalysts for commercial applications are presented.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82807058","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}

The different types of water interaction with zeolites have profound consequences in the stability, structure/composition, and reactivity of these important catalysts. This review analyzes the current knowledge about the mechanistic aspects of water adsorption and nucleation on zeolites surfaces and the concomitant role of zeolite defects, cations and extra framework species. Examples of experimental and computational studies of water interaction with zeolites of varying Si/Al ratios, topologies, and level of silanol defects are reviewed and analyzed. The different steps associated with the process of steaming, including the Al-O-Si bond hydrolysis and subsequent structural modifications, such as dealumination, mesopore formation, and amorphization, are evaluated in light of recent DFT calculations, as well as SS NMR and other spectroscopic studies. Differences between the mechanisms of water attack of the zeolite in vapor or liquid phase are highlighted and explained, as well as the effect of hydrophobic/hydrophilic properties of the zeolite walls. In parallel, the various roles of water as modifier of reactivity are reviewed and discussed, both for plain zeolites as well as rare-earth or phosphorous-modified materials.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76968978","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}

Their unique chemical, mechanical, optical, and electrical properties have been exploited in a wide range of applications, including electrical/optoelectrical devices, solar cells, sensors, membranes, and electro/photocatalysis. However, the application of 2D nanomaterials as thermocatalysts is much less common such that a wide range of questions regarding their activity and stability remain. Herein, the application of 2D transition metal dichalcogenides (TMDs), metal phosphorus trichalcogenides (MPTs) and MXenes as thermocatalysts is reviewed. The data indicate that in most cases, reducing the thickness of the catalyst to that of a single or a few layers of atoms, leads to a significant improvement in product selectivity and reaction rate. However, challenges remain, including the low thermal and chemical stability of 2D nanostructures at typical thermocatalytic operating conditions, facile poisoning of the exposed surface, and rapid loss of activity. In addition, the synthesis procedures for 2D nanostructures are complex, making reproducibility and scale-up difficult. This review identifies knowledge gaps to draw attention to these unique materials that have the potential for significant impact as thermocatalysts.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76543570","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}

The elimination of obstinate sulfur complexes is an enormous task in the current challenging legislative situation for fuel refining companies. The conversion of these obstinate sulfur complexes is challenging in the progression of deeper photocatalytic oxidative desulfurization. As an eco-friendly, inexpensive and non-lethal oxidant with bountiful accessibility, oxygen prevailing in the air is utilized in the deep photocatalytic oxidative desulfurization process as a reliable substitute for hydroperoxide and other expensive hydroperoxide derivatives. However, the superlative activation of oxygen under light irradiations is hitherto a challenge. This potential review critically analyzes the recent strategies employed for the development of efficient materials for the progression of deep aerobic photocatalytic oxidative desulfurization system for the removal of obstinate sulfur complexes. Furthermore, the associated technologies influencing the deep photocatalytic oxidative desulfurization performances have been identified and significant parameters for the process optimization are evaluated to address the forthcoming challenges.
