“…In Figure 1, the appearance of broad diffraction peaks at 37.70°, 45.80°, and 67° confirms (110), (111), and (211) diffraction planes of γ‐Al 2 O 3, respectively. The characteristic peaks of γ‐Al 2 O 3 remains same even after a high loading of Mg content 28,39 . The appearance of a new broad diffraction peak at 19.5° suggests the formation of amorphous Mg‐Al (10) composite 36 .…”

Summary Magnesium‐alumina (Mg‐Al2O3) composite was synthesized by sol‐gel method. The SO42− catalyst supported Mg‐Al2O3 was prepared by three different methods such as solution, hydrothermal, and vapor phase. The as‐synthesized materials were characterized by different physicochemical techniques. The acid sites of Mg‐Al2O3 (10) composite were enhanced by depolymerization of triglyceride (jojoba oil) to produce free FFA. Catalyst prepared by hydrothermal methods exhibits high acid sites of 3.44 mmol g−1 of NH3. Sulfidation of catalysts play a vital role in the catalytic conversion of jojoba oil by methanol activation. SO42−/Mg‐Al2O3 (10) catalyst reveals 99% conversion efficiency tested under optimized conditions of jojoba oil to methyl ester (biodiesel). TGA result confirmed the S2/Mg‐Al2O3 (10) catalyst is stable upto 800°C and weight loss of 19.2%. The recyclability of the S2/Mg‐Al2O3 (10) catalyst reveals reasonably acceptable conversion efficiency after sixth cycle and this catalyst is found to be suitable for the industrial biodiesel production.

Considering the nature of organic contaminants in water, methods of their oxidative decomposition seem to be most appropriate for their removal from contaminated water. There are a lot of methods of chemical oxidation, however, Advanced Oxidation Processes (AOPs) seem to be the most suitable technologies for organic contaminants removal. AOPs belong to a group of processes that efficiently oxidize organic compounds towards harmless inorganic products such as water or carbon dioxide. The processes have shown great potential in treatment of pollutants of low or high concentrations and have found applications for various types of contamination. The hydroxyl radical (•OH) is oxidizing agent used at AOPs to drive contaminant decomposition. It is a powerful, non-selective chemical oxidant, which reacts very rapidly with most organic compounds. Another strong oxidizing agent, singlet oxygen, can be generated by photosensitization of phthalocyanines. Phthalocyanines are molecules based on pyrrol structures connected mainly with methionine groups (–CH=) having a metallic central atom. Illumination upon specific wavelengths initiates formation of singlet oxygen that attack organic contaminants.

“…Shanthi research group studied activity of Ni metal on various supports (SiO 2 , Al−SiO 2 , Al 2 O 3 , Mg‐Al 2 O 3 , MgO, and Mg‐Al 2 O 3 ‐SiO 2 ) for the conversion of eugenol in decalin medium under continuous process [111] . Among the supports, Ni on Mg−Al 2 O 3 −SiO 2 showed high performance to this conversion.…”

Lignin is one of the primary components of lignocellulosic biomass. It is an alternative and sustainable source for aromatic and cyclic hydrocarbons. Lignin is obtained in large quantities as a co‐product in sugar, paper‐pulp, and bioethanol industries. Hydrodeoxygenation/‐hydrogenation of lignin‐based phenolic compounds is an important route to synthesize new generation products. This review focuses on recent catalytic methods for selective conversion of phenolics into cyclohexa(nol/none/ne); which are precursors for emerging polymers and fuels. Furthermore, effect of metal catalysts, supports, and parameters on different reactions were discussed along with possible industrial applications of obtained cycloalkanes. In addition, limitations, advantages, and future scope of hydrodeoxygenation/‐hydrogenation of monolignols are also described.
