“…Wei et al reported zinc oxide-loaded LCFs (ZCFs) prepared by combining electrospinning and thermal treatment. 166 The ZCFs-modified electrode can efficiently improve the electrochemical signal and provide a fast response to HQ with a linear range from 1 × 10 −6 to 5 × 10 −3 mol L −1 and a determination limit of 2.5 × 10 −7 M. Besides, the ZCFsmodified electrode could well separate the oxidation peaks of the three isomers (HQ, catechol (CC), and resorcinol (RS)) under optimum conditions. Therefore, this ZCFs composite is a promising sensor material for detecting HQ.…”

“…Drawing upon the structural attributes of lignin and the adhesive properties of mussels, we employed hydrogen peroxide (HP) to oxidize sodium lignosulfonate (L), aiming in the formation of oxidized lignin (OL) with quinone and aldehyde (carboxyl) structures [34]. The presence of quinone and aldehyde functions in OL enables the formation and development of crosslinking networks with the amino groups present in SM, leading to the enhanced water resistance of SM adhesives.…”

Soybean meal (SM) adhesive is widely acknowledged as a viable substitute for traditional formaldehyde-based adhesives, given its ability to be easily modified, the utilization of renewable sources, and its eco-friendly characteristics. However, the application of SM adhesive in manufacturing has been impeded due to its restricted bonding capacity and inadequate water resistance. Researchers in the wood industry have recognized the significance of creating an SM-based adhesive, which possesses remarkable adhesive strength and resistance to water. This study endeavors to tackle the issue of inadequate water resistance in SM adhesives. Sodium lignosulfonate (L) was oxidized using hydrogen peroxide (HP) to oxidized lignin (OL) with a quinone structure. OL was then used as a modifier, being blended with SM to prepare SM-based biomass (OLS) adhesives with good water resistance, which was found practically through its utilization in the production of plywood. The influence of the HP dosage and OL addition on plywood properties was examined. The changes in the lignin structure before and after oxidation were confirmed using gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS). The curing behavior and thermal stability of OLS adhesives were analyzed using dynamic mechanical analysis (DMA) and thermogravimetric (TG) analysis. The reaction mechanism was also investigated using FT-IR and XPS. The outcomes indicated a decrease in the molecular weight of L after oxidation using HP, and, at the same time, quinone and aldehyde functionalized structures were produced. As a result of the reaction between the quinone and aldehyde groups in OL with the amino groups in SM, a dense network structure formed, enhancing the water resistance of the adhesive significantly. The adhesive displayed exceptional resistance to water when the HP dosage was set at 10% of L and the OL addition was 10% based on the mass of SM. These specific conditions led to a notable enhancement in the wet bonding strength (63 °C, 3 h) of the plywood prepared using the adhesive, reaching 0.88 ± 0.14 MPa. This value represents a remarkable 125.6% increase when compared to the pure SM adhesive (0.39 ± 0.02 MPa). The findings from this study introduce a novel approach for developing adhesives that exhibit exceptional water resistance.

“…To enhance hydrogen production from biomass gasification, Yao et al [17] used three bio-chars as support to prepare nickel based catalysts for the steam gasification of wheat straw. In our other research, different types of carbon materials such as activated carbon [18] and activated carbon fibers [19,20] have also been prepared. Among numerous carbon materials, alkaline activated carbon fibers (ACF) have shown particular advantages, including high specific surface area, rich functional groups and abundant basic sites on the surface [21].…”

Thermodynamics and kinetics are the two key factors in optimizing the biomass derived gas reforming to obtain syngas. In this study, the effects of components of simulated biomass derived gas (CH4, CO2, H2, CO, N2 and steam), reforming conditions and different reactions on products distribution were investigated under thermodynamic equilibrium using Gibbs free energy minimization method so as to optimize the reforming conditions and provide theoretical basis for further reforming of biomass derived gas. The results showed that temperature and steam play an important role in manipulating the ratio of H2/CO during reforming. Changing the temperature and the amount of steam can promote the reverse water-gas shift reaction in different directions thereby the syngas yield can be increased and the H2/CO ratio can be adjusted so as to meet different application requirements. Furthermore, the macroscopic kinetics analysis with a simple power-law type kinetic equation over our previous reported catalyst Ni-Al2O3/ACF (Activated Carbon Fibers) used for the reforming of simulated biomass derived gas was obtained. The influence of carbon fibers on the catalytic performance of nickel-based alumina catalyst was explained in terms of activation energy.
