技术领域technical field
本发明涉及废水降解技术领域，尤其涉及一种镍基电催化剂及产氢协同降解甲醛废水电解池。The invention relates to the technical field of wastewater degradation, in particular to a nickel-based electrocatalyst and an electrolytic cell for synergistically degrading formaldehyde wastewater by hydrogen production.
背景技术Background technique
化石燃料作为不可再生资源被大量消耗，造成了能源短缺和严重的环境污染。因此，迫切需要开发可再生、环保的能源，特别是氢这种高效清洁的能源。通过电催化分解水制氢是一种清洁和环保的方法，但其缓慢的阳极析氧反应仍然是限制其工业上的应用。Fossil fuels are consumed in large quantities as non-renewable resources, resulting in energy shortage and serious environmental pollution. Therefore, there is an urgent need to develop renewable and environmentally friendly energy sources, especially hydrogen, an efficient and clean energy source. Hydrogen production by electrocatalytic water splitting is a clean and environmentally friendly method, but its slow anodic oxygen evolution reaction still limits its industrial application.
研究表明，通过用其他氧化反应代替缓慢的阳极析氧反应，可以促进氢气的产生。其中，甲醛相较于水分子更容易被氧化，进而促进了阴极析氢反应。另一方面，甲醛的危害性众所周知，因此，本发明旨在直接利用甲醛废水作为电解液来提高制氢效率，同时电催化氧化废水中的甲醛。Studies have shown that hydrogen production can be promoted by replacing the slow anodic oxygen evolution reaction with other oxidation reactions. Among them, formaldehyde is more easily oxidized than water molecules, which in turn promotes the cathodic hydrogen evolution reaction. On the other hand, the harmfulness of formaldehyde is well known, therefore, the present invention aims to directly utilize formaldehyde wastewater as an electrolyte to improve hydrogen production efficiency, and at the same time electrocatalytically oxidize formaldehyde in wastewater.
在已有报道中，韩卫清等人提供了一种处理含甲醛废水的装置及方法(CN202010339053.1)，该发明利用钛基二氧化钌电极，通过采用电催化氧化的方法处理废水中的甲醛，但造价较为高昂。李越湘等人提供了磷化钼在碱性甲醛溶液中催化制氢的应用(CN201710715999.1)，该发明用磷化钼在碱性甲醛溶液中催化制氢，但反应需要浓碱液和惰性气体保护，环境不友好。In existing reports, Han Weiqing et al. provide a device and method for treating formaldehyde-containing wastewater (CN202010339053.1). The invention utilizes a titanium-based ruthenium dioxide electrode to treat formaldehyde in the wastewater by using an electrocatalytic oxidation method, But the cost is higher. Li Yuexiang et al. provide the application of molybdenum phosphide to catalyze hydrogen production in alkaline formaldehyde solution (CN201710715999.1), the invention uses molybdenum phosphide to catalyze hydrogen production in alkaline formaldehyde solution, but the reaction requires concentrated lye and inert gas Protection, environment is not friendly.
因此，为了在降解甲醛的同时，明显降低电解池池电压，提高制氢效率，我们提出了以下方案。Therefore, in order to significantly reduce the voltage of the electrolytic cell and improve the hydrogen production efficiency while degrading formaldehyde, we propose the following scheme.
