Due to the important role of oil source in our life, the separation of water-in-oil emulsion is urgent and necessary. Membrane seperation technology has been an efficient and widely used method in separating oil-water separation. Herein, we report a versatile approach to fabricate surface carbonized membranes with self-standing property from biomass-derived precursor by synergistic charring of phytic acid, arginine and filter paper. The obtained membrane exhibited superhydrophobicity in oil, excellent fouling resistance, and self-supporting ability. The membrane can be cycle-used at least 12 times with high permeation flux (up to 1380 L·m⁻²·h⁻¹) and separation efficiency (up to 99.4%).

由于油源在我们生活中的重要作用，油包水型乳液的分离迫在眉睫。膜分离技术已经成为分离油水分离的一种有效且广泛使用的方法。在这里，我们报告了一种通用方法，可以通过植酸，精氨酸和滤纸的协同炭化从生物质衍生的前体制备具有自立性能的表面碳化膜。所得膜在油中显示出超疏水性，优异的耐污垢性和自支撑能力。该膜可循环使用至少12次，具有高渗透通量（高达1380 L·m ^-2 ·h ^-1）和分离效率（高达99.4％）。
