    Mixed solid oxides are known for their excellent catalytic property and applications in environmental remediation. This study presents a green-synthesis route for magnesium oxide–titanium oxide, a mixed oxide demonstrated to possess high performance of phenol removal from hydrocarbon refinery process wastewater. Mixed oxide (MgO-TiO2) was prepared by using the whole extract from leaves of Piliostigma Thonningii as a reducing agent. A structural attribute of the mixed oxide was investigated using X-ray Diffractometer, High Resolution Scanning Electronic Microscopy and Energy Dispersive X-ray. Petroleum refinery raw wastewater having a phenol concentration of 19.961 mg/L was treated using green-synthesized mixed oxide. Adsorptive phenols removal up to 99.5% was achieved with a dosage of 0.04 g/100 mL at a temperature of 35 °C, and a contact time of 1.167 h. By this, the treated water meets the standard acceptable phenol concentration (0.1 mg/L) in wastewater of hydrocarbon refinery. Keywords: Green synthesis; Magnesium oxide; Mixed oxide; Phenol; Process wastewater; Titanium oxide.

    (Wiley-VCH GmbH: ChemBioEng Rev. 2023,, 2023) Fatai Alade Aderibigbe; Harvis Bamidele Saka; Sherif Ishola Mustapha; Mutiu Kolade Amosa; Suleiman Shiru; Idowu Abdulfatai Tijani; Esther Oluwabunmi Babatunde; Bisola Taibat Bello
    Abstract The draining of fossil fuels and their toxic influence on the environment has prompted the need for alternative fuels known as biofuels. Of the various types of biofuel, biodiesel has attracted wide interest in the world today since it promotes carbon neutral ity. The transesterification and interesterification process remains the most widely used process route for biodiesel production. In this review, the perfor mance efficiency of solid base, solid acid, and bi functional solid acid-base catalysts for biodiesel pro duction from waste cooking oil is considered. In particular, the benefit of exploring the biomass derived acid-base heterogeneous bifunctional cata lysts, current status, and future prospects for biodie sel production from waste cooking oil are eluci dated.
