Prof. Zhang Jian’s company developed the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Science (CAS) a cobaltosic oxide (Co.3O4) electrocatalyst for the production of furan combined with hydrogen reaction. The study was published in Catalysis B: Environmental.

Biomass is one of the newest resources in the world. Through catalytic conversion, biomass can be increased in the amount of fuels and chemicals that can replace the old fossil fuels, so it plays an important role in achieving the goal of “carbon peak and carbon neutrality.”

The most important source of energy in the world, solar energy can shorten the energy consumption path and greatly improve the sustainability of the process when incorporated into catalytic reactions.

Due to sulfuration and in-situ electrochemical oxidation, researchers at NIMTE have developed a Co hydrangea-like product.3O4 on the cobalt plate as a good electrocatalyst.

A commercial solar system was used to provide a constant constant voltage of 1.60 ± 0.02 V during the light regulation. Under the real sun, Co3O4 the catalyst was able to completely convert 5-hydroxymethylfurfural biomass (HMF) to 2,5-furandicarboxylic acid (FDCA) with a yield of 93.2%, faradaic efficiency (FE) of 92.9%and hydrogen yield of 99.8%.

Compared to the traditional method of thermally converting HMF to FDCA, which typically requires high temperature, high pressure, negative impact mode, and precious metal catalysts, electrocatalytic photovoltaic technology intended in this study to deal with the earth’s large biomass showing many benefits. , such as low cost standards, low cost, high energy efficiency and safety of operation.

In addition, researchers applied for eight invention patents in related technologies and one patent was issued. This study provides a sustainable development pathway for high -value chemistry and hydrogen production.


Ethers may continue in the future due to heterogeneous catalysis
