Soil, air, and water pollution caused by lignite is considered a serious environmental problem. Activation methods thus have been developed to extract humic acid from support the agricultural production as soil amendment or fertilizer synergist. The traditional activation of lignite, however, are not environmentally friendly. As first study, this work novel solid-phase method with Pd/CeO2 nanocatalyst for lignite-derived acid. This study analyzed morphology structures as-synthesized various...

Bio-based polyurethanes are promising for the controlled release of nutrients and fertilizers, but their toughness plasticity need to be improved. We developed a smooth, dense, elastic, indestructible bio-based polyurethane (BPU) coating with nutrient ∼150% superior, tensile strength ∼300% higher, ∼1200% higher than those original BPU coating. Through one-step reaction soybean oil polyols (accounting more 60%), isocyanate, benzil dioxime, dynamic covalent network based on oxime-carbamate...

Iron (Fe) chelated by water-soluble humic substances can effectively overcome plant micronutrient deficiencies. However, the traditional synthesis methods are often complex, expensive, and thus not applicable to large-scale industrial productions. In this work, an ecofriendly multifunctional Fe–humic acid (HA) complex was successfully prepared through simply ball milling lignite with double-shelled Fe–N hollow mesoporous carbon microspheres (DS–Fe–N–HC). The novel DS–Fe–N–HC synthesized...
