In this study, the impact of the physicochemical behavior of carbon on the melting and crystallization characteristics of gasification slag (GCS) was investigated.

The increased carbon content in GCS facilitates the formation of Fe₃Si at high temperatures. During the cooling process, the liquid phase in the melts deposits to form a dense aluminosilicate matrix, while refractory phases (Fe₃Si and residual carbon) precipitate and coalesce into spherical aggregates. During the quenching process, the high viscosity of aluminosilicate inhibits the precipitation of refractory phases.

This review discusses recent advancements in hydrogen production, with a focus on photoelectrochemical methods and renewable energy-based technologies. Specifically, we discuss the effects of phthalocyanine-based dye sensitizers and catalysts required for photoelectrochemical systems to catalyze hydrogen evolution. This review presents the wide spectrum of hydrogen production technologies, encompassing traditional fossil fuel-based methods and advanced techniques such as water electrolysis with renewable energy input. This review examines the operating principles of water electrolysis cells, maps out technological innovation gaps, and explores development opportunities in proton exchange membranes and solid oxide electrolysis. It gives a review of the recent introduction of phthalocyanines into photoelectrochemical cells, with the beneficial effects of the increased light absorption and electron transfer properties leading to better-earned hydrogen productions. A comparative assessment of these materials for other photocatalysts is also presented in the context that they promise to enhance hydrogen production efficiency while reducing energy consumption. Although significant developments in green hydrogen technologies have been made, the review also suggests that there is still a long road ahead for some of these systems before they can be commercially implemented on a larger scale, even after comprehensive evaluation. The future of sustainable hydrogen production is, in particular, much improved by the promise offered through phthalocyanines.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 7","pages":"4045 - 4074"},"PeriodicalIF":2.5,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting films were characterized using powder X-ray diffraction (p-XRD), scanning electron microscopy (SEM), inductively coupled plasma optical emission spectroscopy (ICP-OES), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS), confirming the successful formation of Re_₁−<i>x</i>Co<i>x</i>S₂ alloys. Various feed ratios of precursors (1) and (2) (10%, 20%, 30%, and 50%) were employed for the synthesis of Co-doped ReS₂films.

A continuous shift was observed from 0.96 to 6.35% Co, while the disappearance of the (001) peak at 8.19% indicated a significant loss of crystallinity, suggesting a transition to an amorphous structure.

Molecular docking revealed binding affinities of − 7.9, − 7.3, and − 6.2 kcal/mol for Nos, Bos, and DHHE, respectively, with Nos exhibiting the strongest interactions through hydrogen bonds and hydrophobic contacts involving residues such as Leu101, Ala335, and Leu336.

In this regard, the objective of our study was to evaluate the effect of the flocculation and pulp parameters of the phosphate slurry on the efficiency of the vacuum filtration of the phosphate. The experiments were planned according to a definitive screening design (DSD), by varying the parameters of six input variables and investigating their impact on the humidity of the phosphate cake and the turbidity of the filtrate.

The factors that affect the humidity of the phosphate the most were identified as the viscosity of the flocculant, followed by the duration of filtration and the specific consumption of the flocculant.
