Metal‐organic gels (MOGs) have emerged as a class of functional materials that show great potential applications in the field of catalysis, energy storage, template synthesis, and environmental technology. The construction of functional MOGs and the control of functionality are still challenging due to complicated chemicals or routes involved in previous works. Here we report a series of tunable multifunctional MOGs by directly gelating between Fe³⁺ and simple chemicals, propanedioic acid (H₂PA), succinic acid (H₂SA), glutaric acid (H₂GA), and fumaric acid (H₂FA) in ethanol. The obtained MOGs exhibit self‐healing property and good conductivity, and were used for high efficacy removal of arsenic (As) in water. The ease, low cost, and scalability of the assembly process combined with multifunctionality make these MOGs be potentially applied in the fields of energy storage and sewage disposal. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3719–3727, 2018

简单化学品的金属有机凝胶及其对水中砷（V）的高效去除

金属有机凝胶（MOG）已成为一类功能材料，在催化，能量存储，模板合成和环境技术领域显示出巨大的潜在应用。由于先前工作中涉及复杂的化学物质或路线，功能性MOG的构造和功能控制仍面临挑战。在这里，我们通过在Fe ³⁺和简单化学品，丙二酸（H ₂ PA），琥珀酸（H ₂ SA），戊二酸（H ₂ GA）和富马酸（H ₂）之间直接胶凝，报告了一系列可调多功能MOG。FA）在乙醇中。所获得的MOG具有自我修复性能和良好的导电性，可用于高效去除水中的砷（As）。组装过程的简便，低成本，可扩展性与多功能性相结合，使得这些MOG可以潜在地应用于储能和污水处理领域。©2018美国化学工程师学会AIChE J，64：3719–3727，2018
