Investigation of the roles of lignin in biomass-based hydrogel for efficient desalination

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 7,   Pages 954-965 doi: 10.1007/s11705-023-2311-2

Abstract: The shortage of freshwater has become a global challenge, and solar-driven interfacial evaporation for desalination is a promising way to alleviate the crisis. To develop highly efficient and environmentally friendly photothermal evaporator, the hydroxyethyl cellulose (HEC)/alkaline lignin (AL)/graphene oxide (GO) hydrogels (CLGs) with remarkable evaporative performance were successfully fabricated by a facile sol–gel method using biomass residues. The influence of AL content on the physicochemical properties of the evaporator was investigated. The increasing content of AL improves the mechanical properties, saturated water content and crosslink density of the hydrogels. The designed materials exhibit outstanding thermal insulation capacity (the thermal conductivity of less than 0.05 W·m–1·K–1) and high light absorption capacity of more than 97%. The solar evaporation efficiency and water evaporation rate of the HEC/64 wt % of AL/GO hydrogels (CLG4) achieve 92.1% and 2.55 kg·m–2·h–1 under 1 sun, respectively. The salt resistance test results reveal that the evaporation rate of the CLG4 can still reach 2.44 kg·m–2·h–1 in 3.5 wt % NaCl solution. The solar evaporation rate of the CLG4 can maintain in the range of 2.45–2.59 kg·m–2·h–1 in five cycles. This low-cost lignin-based photothermal evaporator offers a sustainable strategy for desalination.

Preparation of hydrogels with uniform and gradient chemical structures using dialdehyde cellulose and diamine by aerating ammonia gas

Peiwen Liu, Carsten Mai, Kai Zhang

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 3,   Pages 383-389 doi: 10.1007/s11705-018-1718-7

Abstract:

Hydrogels with precisely designed structures represent promising materials with a broad application spectrum, such as for sensor, tissue engineering and biomimetic technology. However, with highly reactive compounds, the preparation of hydrogels still needs an efficient approach for desired distribution of each component within hydrogels. In addition, a method for in situ preparation of gradient hydrogels is still lacking. Herein, we report the formation of hydrogels with either uniform or gradient internal structures via a novel, simple but very efficient method by aerating ammonia gas (NH3 gas) into the solution of dialdehyde cellulose (DAC) and a diamine. As-prepared hydrogels exhibited uniform microscopic and chemical structure or gradient distribution of functional groups. Due to lots of aldehyde groups on DAC chains, functional hydrogels can be prepared by using diverse diamines. For instance, hydrogels prepared by using 1,6-hexanediamine as a cross-linker were responsive to pH values. Moreover, this controllable process of aerating NH3 gas allows the in situ formation of gradient hydrogels; for instance, by using cyanamide as a reaction counterpart, gradient hydrogels with gradient distributions of cyanide groups were prepared.
