Hu Yong on Energy & Environmental Science
Post Time: 09/05/2018

The research team led by Hu Yong, professor at Zhejiang Normal University and expert in sci-tech innovation projects, published an article -- in cooperation with professor Lou Xiongwen of Nanyang Technological University --  titled “Construction of Uniform Hierarchical Ni-Co-P Hollow Nanobricks with 2D Nanosheets for Efficient Overall Water Splitting”, on the online edition of the academic journal Energy & Environmental Science (IF=29.518). Published by the Royal Society of Chemistry, the journal ranks at the forefront of over 400 journals about chemical, physical and biotechnological sciences relating to energy conversion and storage, alternative fuel technologies and environmental science. Graduate students, Hu Enlai, Feng Yafei are listed as first co-authors representing Zhejiang Normal University, which appears for the first time as primary affiliation on this journal.

       Overall water splitting electrocatalysts play a significant role in the mitigation of fossil energy crisis and energy storage. Although noble-metal electrocatalysts (Pt/C, Ru2O and Ir2O) have exhibited good performances in overall water splitting, they cannot be used for large-scale production due to their scarcity. Finding inexpensive, stable and efficient electrocatalysts for water splitting is the actual and critical problem to be solved.

       Hu Yong's research team chooses low-cost multi-component transition metal  phosphides as target product. For the first time, a series of open and hierarchical Ni–Co–P hollow nanobricks (HNBs) via the assembly of oriented 2D nanosheets was produced using Ag2WO4 nanobricks as templates by subsequent heating, etching and phosphorization treatments,. The unique nano-architectures not only greatly shorten the proton transmission distance, but also provides abundant mass diffusion pathways, which gives the product excellent electrocatalytic water splitting properties and provides new research prospects for the development of electrocatalytic materials.

       The work is sponsored by the National Natural Science Foundation of China and the Zhejiang Outstanding Youth Fund.
