Abstract
Electrochemical ammonium (NH4+) storage (EAS) has been established as an efficient technology for NH4+ recovery from wastewater. However, there are scientific difficulties unsolved regarding low storage capacity and selectivity, restricting its extensive engineering applications. In this work, electrochemically selective NH4+ recovery from wastewater was achieved by coupling hydrogen bonding and charge storage with self-assembled bi-layer composite electrode (GO/V2O5). The NH4+ storage was as high as 234.7 mg N g-1 (> 102 times higher than conventional activated carbon). Three chains of proof were furnished to elucidate the intrinsic mechanisms for such superior performance. Density functional theory (DFT) showed that an excellent electron-donating ability for NH4+ (0.08) and decrease of diffusion barrier (22.3 %) facilitated NH4+ diffusion onto electrode interface. Physio- and electro-chemical results indicated that an increase of interlamellar spacing (14.3 %) and electrochemical active surface area (ECSA, 388.9 %) after the introduction of GO were responsible for providing greater channels and sites toward NH4+ insertion. Both non-ionic chemical-bonding (V5+=O‧‧‧H, hydrogen-bonding) and charge storage were contributed to the higher capacity and selectivity for NH4+. This work offers underlying guideline for exploitation a storage manner for NH4+ recovery from wastewater.

Abstract
A novel Bi13S18I2 structure was synthesized using a facile one-pot hydrothermal method and further optimized as an anode material using graphene. The graphene/Bi13S18I2 composite achieved a high discharge capacity with an initial value of 1126.5 mA h g-1 and a high and stable discharge capacity of 287.1 mA h g-1 after 500 cycles compared with pure Bi13S18I2, which derives from the inhibited volume expansion and high electrical conductivity obtained from graphene. In situ XRD was performed to analyze the Li storage mechanism in depth. The results support the feasibility of the new ternary sulfide Bi13S18I2 as a promising lithium ion battery.
