Based on that， the excellent mechanical properties and abundant porous structure of cellulose nanofibers （CNF） were combined to prepare the PQDs@CNF composite reinforced films， which enabled the BVA-CsPbBr₃ PQDs to be uniformly dispersed and firmly anchored in the CNF fiber network， effectively avoiding the agglomeration of the PQDs and enhancing the mechanical strength of the PQDs@CNF composite reinforced films. The results showed that the PQDs@CNF composite reinforced films had excellent luminescence and mechanical properties， which not only retained the original high photoluminescence intensity of BVA-CsPbBr₃ PQDs， but also had the environmental adaptability and stability due to the combination with CNF.]]> 2024/12/23 0:00:00 XING Jialong,MA Cong,ZHANG Jingru,ZHANG Meiyun 4true 2-loaded Ni single atom catalyst Ni₁/CeO₂ that can be used to catalysis the hydrogenolysis of lignin was prepared by an impregnation-pyrolysis-reduction strategy. It was found that the abundant oxygen vacancies in the CeO₂ supporter facilitated the high dispersion of Ni single atoms on the CeO₂ surface， and synchrotron radiation demonstrated that the Ni atoms could be linked with four O atoms to form the NiO₄ catalytic activity centre. The catalyst Ni₁/CeO₂ not only exhibited excellent activity in catalyzing the hydrogenolysis of lignin model compounds diphenyl ether （4-O-5）， benzyl phenyl ether （α-O-4）， and 2-phenoxy-1-phenylethanol （β-O-4）， but also showed good performance in catalyzing lignin depolymerization， giving the hydrogenolysis products of lignin a good prospect for application.]]> 2024/12/23 0:00:00 LI Fuhua,LIU Yunzhuo,LU Tingjie,SUN Jiancheng,YU Xinyu,WEN Zhengtang,ZHOU Yaosen,XIA Xuelian,GUO Ming,SHI Changbo,HE Qian 3true Miscanthus using citric acid pretreatment combined with high-pressure homogenization， and LCNF aerogel was obtained after freeze-drying. The adsorption performance and mechanism of the aerogel towards cationic dye Rhodamine B （RB） was investigated. The results showed that the adsorption capacity towards RB by LCNF aerogel was the best under neutral conditions， and the equilibrium adsorption capacity increased to 40.0 mg/g at 55 ℃. The adsorption kinetics and thermodynamics studies showed that the adsorption towards RB by LCNF aerogel conformed to the pseudo-second-order kinetic model， which was mainly dominated by chemical adsorption and spontaneous. There were some interactions such as hydrogen bonding and electrostatic attraction between LCNF and RB during the adsorption process. In addition， LCNF aerogel showed good reusability and the removal rate of RB remained above 83% after four cycles.]]> 2024/12/23 0:00:00 CHEN Lidong,DUAN Sheng,WU Jin,LIU Chao,YAO Shuangquan,XU Tingting,DAI Hongqi,BIAN Huiyang 2true 2024/12/23 0:00:00 ZHANG Juntao,XIE Yuxin,ZHAO Mingwei,ZHAO Yurong,LIAO Guangfu 1true
