“…For example, the majority of the publications Lievonen et al 2016;Sipponen et al 2017), ethylene gycol (Richter et al 2016;Yang et al 2018aYang et al , 2018bFrangville et al 2012), and dioxane (Qian et al 2014;Li et al 2016), which are toxic. Some publication reported on using acidic water to precipitate or induce lignin nanoparticles (Azimvand et al 2018;Richter et al 2015). Use and manipulation of aforesaid solvents or aqueous solutions are more complicated and expensive than those of ubiquitous acetone used in this current work.…”

“…The preparation of lignin particles (LPs) was achieved from alkali lignin by using acid precipitation . Briefly, 0.56 g of alkali lignin was dissolved in 100 mL of poly(ethylene glycol) solution (0.49 wt %) under magnetic stirring at a temperature of 40 °C for 2 h, followed by centrifugation to remove the insoluble impurities.…”

Frequent oil spills and the discharge of oily wastewaters have caused a serious threat to the environment, ecosystems, and human beings. Herein, a photothermal and superhydrophobic melamine sponge (MS) decorated with MXene and lignin particles has been prepared for the separation of oil/water mixtures, the recovery of crude oils, and active deicing. The obtained superhydrophobic melamine sponge shows a water contact angle (WCA) of 152.3° and an oil contact angle of ∼0° and possesses good chemical stability, thermal stability, and mechanical durability in terms of being immersed in various liquids (i.e., corrosive solutions, organic solvents, and boiling water) and being abrased by sandpapers. This superhydrophobic MS displays a high oil adsorption capacity of CCl4, up to 91.6 times its own weight and a high separation efficiency of 99.4%. Furthermore, the maximum surface temperature of the superhydrophobic MS reaches 57.5 °C under sunlight irradiation (1.0 kW/m2) due to the excellent photothermal heating conversion performance of MXene and lignin particles. When exposed to sunlight, the superhydrophobic MS can quickly absorb viscous crude oils up to 72 times its own weight. Also, the WCA of the superhydrophobic MS remains above 146° after 50 icing/deicing cycles, showing excellent photothermal anti-icing properties. Thus, this study presents an easy and low-cost method for designing photothermal superhydrophobic melamine sponges and opens a new avenue to the applications of efficient oil/water separation, fast crude oil recovery, and active deicing.

Lignin nanoparticles, the innovative achievements in the development and utilization of lignin, combine the structural characteristics of nanomaterials and lignin molecules and have a wide range of applications. In this review, we summarize the methods for preparing lignin nanoparticles by solvent exchange method, mechanical method, biological enzymatic method, interface polymerization/crosslinking method, and spray freezing method, and emphatically introduce the application prospects of lignin nanoparticles in ultraviolet protection, antibacterial, nano-filler, drug delivery, and adsorption, aiming to provide a certain reference direction for additional high-value applications of lignin nanoparticles.
