Initiating A Mild Aqueous Electrolyte Co3O4/Zn Battery with 2.2 V-High Voltage and 5000-Cycle Lifespan by a Co(III) Rich-electrode

26-Jun-2018 | Longtao Ma; Shengmei CHEN; Hongfei Li; Zhaoheng Ruan; Zijie Tang; Zhuoxin Liu; Zifeng Wang; Yan Huang; Zengxia Pei; ..., Energy & Environmental Science, 2018

Zn/Co3O4 battery is one of the few aqueous electrolyte batteries with a potential >2 V voltage. Unfortunately, so far, all reported Zn/Co3O4 batteries are using alkaline electrolyte, resulting in a poor cycling stability and environmental problems. Here, we report a Co(III) rich- Co3O4 nanorod ...

Selective CO2 reduction to C3 and C4 oxyhydrocarbons on nickel phosphides at overpotentials as low as 10 mV

26-Jun-2018 | Karin U. D. Calvinho; Anders B. Laursen; Kyra M. K. Yap; Timothy A. Goetjen; Shinjae Hwang; Bryan Mejia-Sosa; Alexan ..., Energy & Environmental Science, 2018

We introduce five nickel phosphide compounds as electro-catalysts for the reduction of carbon dioxide in aqueous solution, that achieve unprecedented selectivity to C3 and C4 products (the first such report). Three products: formic acid (C1), methylglyoxal (C3) and 2,3-furandiol (C4), are ...

Efficient visible-light-driven selective oxygen reduction to hydrogen peroxide by oxygen-enriched graphitic carbon nitride polymers

26-Jun-2018 | Zhen Wei; Meili Liu; Zijian Zhang; Wenqing Yao; Hongwei Tan; Yongfa Zhu, Energy & Environmental Science, 2018

H2O2 is a green environment and potential energy material. Photocatalytic reduction of molecular oxygen to synthesis H2O2 is an eco-friendly strategy compared the anthraquinone method and H2/O2 directly synthesize. We proposed an oxygen-enriched carbon nitride polymer (OCN) models, which were ...

Vertical Co9S8 hollow nanowall arrays grown on Celgard separator as a multifunctional polysulfide barrier for high-performance Li-S batteries

26-Jun-2018 | Jiarui He; Yuanfu Chen; Arumugam Manthiram, Energy & Environmental Science, 2018

Lithium-sulfur (Li-S) batteries have been regarded as one of the most promising next-generation energy-storage devices, due to their low cost and high theoretical energy density (2600 W h kg-1). However, the severe dissolution of lithium polysulfides (LiPSs) and fatal shuttle effect of sulfur ...

Slow surface passivation and crystal relaxation with additives to improve device performance and durability for tin-based perovskite solar cells

26-Jun-2018 | Efat Jokar; Cheng-Hsun Chien; Yu-Hao Chang; Amir Fathi; Mohammad Rameez; Eric Wei-Guang Diau, Energy & Environmental Science, 2018

We investigated the doping effect of bulky organic cations with ethyl diammonium diiodide (EDAI2) and butyl ammonium iodide (BAI) as additives to passivate the surface defects, to control the film morphology and to improve the crystallinity for the inverted planar FASnI3 perovskite solar cells. ...

Towards Reliable Li-metal-free LiNO3-free Li-ion Polysulphide Full Cell via Parallel Interface Engineering

20-Jun-2018 | Ju Sun; Jiaxing Liang; Junnan Liu; Wenyan Shi; Neeraj Sharma; Wei Lv; Ruitao Lv; Q. H. Yang; Rose Amal; Dawei Wang, Energy & Environmental Science, 2018

There has been intensive concentration and effort on addressing the notorious challenges of Li-S batteries with respect to the polysulphide utilization and the lithium dendrite inhibition. However, the search and optimisation of the Li-metal-free full cell design remain relatively pre-mature in ...
