Abstract
Coal tar wastewater is hard to degrade by traditional methods because of its toxic pollutant constituents and high concentration of aromatic hydrocarbons, especially phenolic substances. A new type of hydrophobic benzacetone modified PbO2 anode (BA-PbO2 electrodes) was used for the electrocatalytic treatment of coal tar wastewater in a continuous cycle reactor. The surface morphology, structure, valences of elements, hydrophobicity, hydroxyl radical (·OH) produced capacity, electrochemical properties and stability of BA-PbO2 electrodes were characterized by SEM (scanning electron microscopy), XRD (X-ray diffraction), XPS (X-ray photoelectron spectroscopy), contact angle, a fluorescence probe test, an electrochemical workstation and accelerated life test, respectively. The BA-PbO2 electrodes exhibited a compact structure and finely dispersed crystallize size of 4.6 nm. The optimum degradation conditions of coal tar wastewater were as follows: current density of 90 mA cm-2, electrode gap of 1 cm and temperature at 25 °C with flow velocity of 80 L h-1. The chemical oxygen demand (COD) removal efficiency reached 92.39% after 240 min of degradation under the optimized conditions and the after-treatment COD value was 379.51 mg L-1 which was lower than the centralized emission standard (less than 400 mg L-1). These findings demonstrated the feasibility and efficiency of electrocatalytically degrading coal tar wastewater by BA-PbO2 electrodes. The possible mechanism and pathway for phenol a specific pollutant in coal tar wastewater were investigated by quantum chemistry calculations (Multiwfn) and gas chromatography-mass spectrometry (GC-MS). The toxicity of each intermediate was predicted by the ECOSAR program.

Abstract
Li metal is considered the most promising anode for high energy density secondary batteries due to its high theoretical capacity and low redox potential. However, lithium is prone to form dendrites which will not only cause internal short-circuits but also bring accumulation of "dead Li" and result in fast capacity decay, thus its large-scale application is challenging. In this work, we demonstrate that the commonly used metal corrosion inhibitor, benzotriazole (BTA), can be used to modify the Cu foil surface and guide homogeneous Li+ plating/stripping due to the lithiophilic nature of the N atom in the BTA molecule. As a result, the lithium plated on the BTA modified Cu (BTA-Cu) substrate is free of dendrites, and a Coulombic efficiency (CE) as high as 99.0% was achieved for Li+ plating/stripping on the BTA-Cu substrate at a current density of 1 mA/cm2. Furthermore, the BTA-Cu foil can be used as an anode to assemble an anode-free cell (BTA-Cu∥LFP), and ∼73.3% of the initial capacity can be obtained after 50 cycles. Last but not the least, a BTA-Cu@Li electrode prepared by plating of Li+ on the BTA-Cu substrate can serve as a stable Li anode in a BTA-Cu@Li∥LFP cell and display an average cycled CE of 98.5% at a depth of discharge (DOD) of 33%. This simple method of Li+ plating/stripping behavior regulation could inspire researchers on the development of highly stable lithium metal anodes for high energy density batteries.
