Abstract The growing population and the unpalatable ecological impact of exploration utilization fossil-based fuels have resulted in increased demand for biofuel as an alternative fuel engines power generation. global biodiesel, a prominent member biofuels family, has continued to increase over past decades with researchers devising various means intensify cost-effective production. use metal oxide nanocatalysts is one feasible strategies meet quality biodiesel. This study reviews recent advances deployment commonly used nanoparticles such MgO, CaO, TiO 2 , ZnO, ZrO accelerate sustainable biodiesel Converting conventional heterogeneous catalysts into enhances surface configuration, chemical thermal stability, porosity, crystallinity nanocatalysts. hasten transesterification reaction, reduces reaction temperature time, yield. Biodiesel synthesized aid impeccable meets international standards. Notwithstanding few challenges, application engenders production contributes energy security. More innovative collaborative studies are needed reduce ethical, economic, infrastructural, environmental consequences usage nanomaterials

Abstract DHHB (n-hexyl 2-(4-N,N-diethylamino-2-hydroxybenzoyl) benzoate) is a recently developed UV absorber that demonstrates high degree of safety, excellent efficiency, and favorable solubility properties. In this paper catalyst was prepared to catalyze the esterification with homemade sulfonic acid modified polystyrene microspheres coated silica instead conventional H 2 SO 4 . And characterized by scanning electron microscopy (SEM) infrared spectroscopy (FT-IR). The effects different conditions on reaction rate equilibrium conversion were also investigated using as benchmark. results showed catalytic activity did not decrease significantly after 10 consecutive cycles, yield could reach 90.21 % h at 150 °C. Meanwhile, kinetic experimental data obtained correlated proposed homogeneous phase model. synthesis heat-absorbing heat activation energies 4.6537 kJ/mol, 43.2157 kJ/mol 37.5735 for forward reverse reactions, respectively. It verified model accurately described processes reaction.
