This study focuses on the sustainable production of bio‐jet fuel through the catalytic hydrodeoxygenation (HDO) of isoeugenol (IE). Sucrose‐based activated carbon supported bimetallic Platinum‐Tin metal sulphides (PtO‐SnS/AC) catalyst was prepared for HDO process. Physicochemical properties of catalysts with different spraying synthesis methods (in situ and ex situ metal doping) and Pt loading (0.1–1.0 %) were further investigated. The PtO‐SnS/AC catalysts were characterised using various techniques such as X‐ray absorption spectroscopy (XAS), X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM), field‐emission scanning electron microscopy (FESEM) and thermogravimetric analysis (TGA). Both HRTEM and FESEM results show the successful preparation of a spherical nanoparticles doped over activated carbon, and Pt was dispersed on the outer shell of the particles. The catalytic HDO of IE was evaluated in a batch system and showed a high yield and conversion as follows: IE conversion of 100 %, liquid‐phase mass balance of 95.92 %, dihydroeugenol (DH) conversion of 99.32 %, propylcyclohexane (PCH) yield of 88.94 % and 2‐methoxy‐4‐propylcyclohexanol (HYD) yield of 76.19 %. Moreover, the PtO‐SnS/AC catalyst exhibited high reusability with low metal leaching and high coke resistance for 10 cycles. The catalyst was evaluated in a continuous flow reactor for 100 h at different reaction temperatures, and interestingly, the catalyst showed low deactivation with a high half‐time.

Corrosion threatens materials in diverse industries, necessitating sustainable corrosion inhibitors. Polysaccharides, abundant natural polymers, emerge as eco‐friendly corrosion inhibitors. This review explores polysaccharides' efficacy, mechanisms, and applications. It introduces the significance of corrosion and the vital role of inhibitors, positioning polysaccharides as promising green solutions. The exploration covers polysaccharide diversity, sources, and eco‐friendly attributes. Corrosion mechanisms are detailed, setting the stage for understanding inhibition strategies. Polysaccharides, with unique adsorption and film‐forming properties, are effective inhibitors, elucidated through electrochemical studies. Influential factors like pH, temperature, and concentration effects, along with practical applicability considerations, are examined. Real‐world implementations across industries underscore polysaccharides' versatility, often surpassing traditional inhibitors. Despite challenges, this review outlines their promising role, addressing concerns and proposing future directions. Polysaccharides emerge as eco‐friendly alternatives, illuminating inhibitive properties, mechanisms, and practical applications, guiding continued research for sustainable corrosion prevention.
