Preparation of Biodiesel Catalyzed by Supported Ionic Liquids Biodiesel is an alternative fuel to fossil fuels with properties such as highiy biodegradable, renewable and non-toxic. Therefore, biodiesel holds significant importance in terms of sustainable development. Supported ionic liquids (SILs) combine the superior properties of ionic liquids with the stability of solid materials, making them ideal candidates for producing biodiesel through transesterification.

O-phenylenediamine (OPD), a typical representative of aniline compounds found in non-aqueous phase liquids (NAPLs), is extensively released into groundwater and adheres to aquifers through industrial discharges or as breakdown products of pesticides or herbicides [1]. Given its substantial toxicity and suspected carcinogenicity (Lethal Dose, 50% (LD50) = 1070 mg/kg), a reliable, swift, and eco-friendly method for removing OPD from groundwater is urgently needed [2], [3].

Interfacial solar vapor generation (ISVG) is a technology that limits solar photogenerated heat to the gas–liquid interface to achieve a highly efficient water vapor phase change, which can sufficiently reduce heat loss and has the advantage of zero carbon emission [1], [2], [3], [4]. Due to its simple structure and low operating environment requirements, ISVG can be used in complex applications such as seawater desalination, brine concentration and wastewater treatment [5], [6], [7], [8].
