To improve fertilizer use efficiency, reduce irrigation requirement, and minimize negative environmental impact, a novel large-grained-activated-lignite-slow-release fertilizer (LAF) with good water retention was developed by mechanical extrusion of activated lignite and conventional fertilizer. A 3D molybdate-sulfur hierarchical hollow nanosphere (3D-MoS₂–HN) catalyst was successfully fabricated via a simple route, and the lignite was activated by 3D-MoS₂–HN to increase its water-soluble humic acid content and nutrient adsorption ability. After activation, the amounts of small molecular active groups and water-soluble humic acid of activated lignite were significantly higher than those of raw lignite. The activation also increased adsorption ability of the activated lignite for nutrients. LAF prepared from the activated lignite had a preferable slow-release property and good water-holding capacity in soil. Moreover, a pot trial further demonstrated that LAF effectively improved the growth of an apple plant. With outstanding water-retention and slow-release capacities, this new fertilizer is economical and eco-friendly, and thus is promising in field applications.

由3D-钼酸盐-硫分层空心纳米球催化剂活化褐煤制备的多功能缓释肥料

为了提高肥料利用率，减少灌溉需求并最大程度地减少对环境的不利影响，通过机械挤压活性褐煤和常规肥料，开发了一种新型的具有良好保水性的大颗粒活性褐煤缓释肥料（LAF）。通过简单的方法成功地制备了3D钼酸盐-硫分层空心纳米球（3D-MoS ₂ -HN）催化剂，褐煤被3D-MoS ₂活化-HN增加其水溶性腐殖酸含量和养分吸收能力。活化后，活化褐煤的小分子活性基团和水溶性腐殖酸的量明显高于未加工褐煤。活化还增加了活化褐煤对养分的吸附能力。由活化褐煤制备的LAF具有较好的缓释性能，并在土壤中具有良好的保水能力。此外，盆栽试验进一步证明LAF有效改善了苹果植物的生长。这种新型肥料具有出色的保水和缓释能力，既经济又环保，因此在田间应用中很有希望。
