Abstract: Electrocatalytic N2 reduction reaction (NRR) represents a sustainable and promising technology for producing NH3 at ambient conditions. Herein, we demonstrated that Mo-doping could change the MnO2 from an inert material into one that can efficiently and robustly catalyze NRR in neutral media. The developed Mo-doped MnO2 nanoflowers (Mo-MnO2 NFs) exhibited a significantly enhanced NRR performance with an NH3 yield of 36.6 μg h−1 mg−1 (-0.5 V) and an FE of 12.1 % (-0.4 V), far outperforming undoped MnO2 NFs and comparing favorably to most reported NRR catalysts. Density functional theory calculations revealed the electron-deficient character of Mo dopants that delivered multi-functions for NRR enhancement: (1) inducing a defect level to promote the conductivity of MnO2, (2) serving as the key NRR active sites, (3) activating the inert Mn sites for enhancing the intrinsic NRR activity of MnO2, (4) retarding the binding of Lewis acid H+ to suppress the hydrogen evolution reaction.

TL;DR: The occurrence, distribution and bioaccumulation of 22 antibiotics, including eight fluoroquinolones (FQs), nine sulfonamides (SAs) and five macrolides (MLs), in the Haihe River were investigated and sediments are an important reservoir for FQs as they are strongly adsorbed onto sediments.
Abstract: The occurrence, distribution and bioaccumulation of 22 antibiotics, including eight fluoroquinolones (FQs), nine sulfonamides (SAs) and five macrolides (MLs), in the Haihe River were investigated. Surface water, sediment and fish samples were analyzed by HPLC-MS/MS. Ofloxacin, sulfamethoxazole, sulfadiazine, erythromycin and roxithromycin were found in all surface water samples. SAs were the predominant antibiotics in surface water samples in the mainstream of Haihe River, with the maximum concentration of 201 ng L−1 for sulfamethoxazole. Compared with Haihe River, higher concentrations of antibiotics were found in the surface water samples in the Dagu and Chentaizi Drainage Rivers. The antibiotics pollution in the mainstream of Haihe River may derive from its tributaries, whereas the wastewater from fish ponds was not the main source of FQs, SAs and MLs in the river water. In sediment samples, FQs were the most frequently detected antibiotics and their concentrations were much higher than SAs and MLs. The high concentrations and detection frequencies of FQs in sediments indicate that sediments are an important reservoir for FQs as they are strongly adsorbed onto sediments. Ciprofloxacin and erythromycin exhibited potential bioaccumulation in crucian carp, with mean bioaccumulation factors of 3262 L kg−1 and 4492 L kg−1, respectively.

TL;DR: Li4−xAlxTi5O12 was synthesized via solid state reaction in an Ar-flowing atmosphere as discussed by the authors, where the substitution of Al for Li site can enhance the electronic conductivity and impede the Li-ion diffusion in the lattice.
