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.
