| description | Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) steaming, a green and highly efficient delignification method, has been demonstrated to provide a wood skeleton with a very low content of residual lignin in the manufacturing of transparent wood. It usually requires a long reaction time and a large amount of H<sub>2</sub>O<sub>2</sub> because the piece of wood is treated using steaming equipment. Herein, a H<sub>2</sub>O<sub>2</sub> solution steaming method was developed for the highly efficient removal of lignin from wood. Specifically, several wood samples were simultaneously immersed in a hot H<sub>2</sub>O<sub>2</sub> solution to obtain delignified wood with a relatively high content of residual lignin, which provided a high strength and preserved the cellulose skeleton. Subsequently, the delignified wood with a relatively high content of residual lignin was further treated with H<sub>2</sub>O<sub>2</sub> steam to obtain a very low lignin delignified wood. Compared with the previous H<sub>2</sub>O<sub>2</sub> steaming method, the reaction time and used H<sub>2</sub>O<sub>2</sub> volume of the H<sub>2</sub>O<sub>2</sub> solution steaming method was reduced by 37.3% and 52.7%, respectively. All-biomass transparent wood could be obtained by infiltrating the delignified wood with cellulose acetate, which showed both a high transmittance of 83.0% and a low thermal conductivity of 0.30 Wm<sup>−1</sup>K<sup>−1</sup>. |
