Sustainable biochar as an electrocatalysts for the oxygen reduction reaction in microbial fuel cells

Shengnan Li, Shih-Hsin Ho, Tao Hua, Qixing Zhou, Fengxiang Li*（李凤祥）, Jingchun Tang

Biochars are produced from neutral sources (i.e., agricultural wastes). The morphology and catalytic performance of biochar electrodes must be elucidated through measurements. Overall, biochars possess remarkable electrocatalytic properties for ORRs and are considered to be ORR electrocatalysts with developmental potential.

Hydrogen production via chemical looping reforming of coke oven gas

Kun Yang, Zhenhua Gu, Yanhui Long, Shen Lin, Chunqiang Lu, Xing Zhu, Hua Wang, Kongzhai Li*（李孔斋）

Chemical looping reforming of coke oven gas to produce pure H₂ is proposed in the present work by using La_1-xSr_xFeO₃ perovskite oxides as oxygen carriers. The doping of suitable amounts of Sr in LaFeO₃ perovskite (e.g., La_0.5Sr_0.5FeO₃) significantly promotes the reactivity for selective oxidation of methane to syngas and inhibits the formation of carbon deposition.

MOF-derived zinc manganese oxide nanosheets with valence-controllable composition for high-performance Li storage

Yu Du¹, Yihan Xu¹, Weiwei Zhou*（周薇薇）, Yaoyang Yu, Xinzhou Ma, Fei Liu, Jinglong Xu, Yongming Zhu

The porous ZMO nanosheets were obtained from 2D MOF precursors using PVP as a soft template. By analyzing ZMOs from different annealing temperature, we disclosed that the higher-valent Mn the ZMO contains, the more additional capacity it gains upon cycling.
