A photocatalytic approach for the conversion of xylose into furfural using SO2– 4/TiO2–ZrO2/La3+ as a photocatalyst was studied at low temperature (120 C) under ultraviolet irradiation (365 nm). The introduce of sulfate ion and lanthanum can enhance the photocatalytic performance of composite metal oxides. 31.6% conversion efficiency and 216.6 μmol/g furfural yield were achieved when using 1.0 M-SO2– 4/TiO2–ZrO2/1.0 wt%–La3+ at 120 °C for 4 h, which is sharply higher than non-catalytic process and no ultraviolet irradiation process. This means that the cooperation of SO2– 4/TiO2– ZrO2/La3+ and ultraviolet irradiation could greatly enhance the furfural yield and xylose conversion efficiency. The mechanism of conversion of xylose into furfural using SO2– 4/TiO2–ZrO2/La3+ under ultraviolet irradiation was proposed. Therefore, this work will encourage subsequent research for the future utilization of renewable carbon sources under mild operational conditions.

  • The goal of the creation of a biobased economy is challenging to agriculture, forestry, academia, government and industry. The extractable resources of the Earth are finite, regardless of the quibble over when they will be depleted. The economic, political and social demands for biobased chemicals, materials and energy are expected to radically transform the materials industries, particularly the plastics industry as well as the biofuel industry. These changes will be based on the principles of sustainability, eco-efficiency, industrial ecology, and green chemistry and engineering. In keeping with the growth of knowledge in this field, there is a strong need for a forum to share original research related to biobased materials and bioenergy. The Journal of Biobased Materials and Bioenergy (JBMB) has been created as an international peer-reviewed periodical to fulfill the need for communication in these research areas. This journal will encompass related research activities in all fields of science, engineering and the life sciences.
