Core–shell CoFe₂O₄@Co–Fe–Bi nanoarray: a surface-amorphization water oxidation catalyst operating at near-neutral pH

Nanoscale (2017)

Xuqiang Ji Shuai Hao Fengli Qu Jingquan Liu Gu Du

The exploration of high-performance and earth-abundant water oxidation catalysts operating under mild conditions is highly attractive and challenging. In this communication, core–shell CoFe2O4@Co–Fe–Bi nanoarray on carbon cloth (CoFe2O4@Co–Fe–Bi/CC) was successfully fabricated by in situ surface amorphization of CoFe2O4 nanoarray on CC (CoFe2O4/CC). As a 3D water oxidation electrode, CoFe2O4@Co–Fe–Bi/CC shows outstanding activity with an overpotential of 460 mV to drive a geometrical catalytic current density of 10 mA cm−2 in 0.1 M potassium borate (pH 9.2). Notably, it also demonstrates superior long-term durability for at least 20 h with 96% Faradic efficiency. Density functional theory calculations indicate that the conversion from OOH* to O2 is the rate-limiting step and the high water oxidation activity of CoFe2O4@Co–Fe–Bi/CC is associated with the lower free energy of 1.84 eV on a Co–Fe–Bi shell.

Efficient Electrochemical N₂ Reduction to NH₃ on MoN Nanosheets Array under Ambient Conditions

ACS Sustainable Chemistry & Engineering (2018)

Ling Zhang Xuqiang Ji Xiang Ren Yonglan Luo Xifeng Shi

Electrochemical N2 reduction reaction (NRR) under ambient conditions offers us an environmentally friendly route for artificial synthesis of NH3. However, up to now, few noble-metal-free electrocatalysts with satisfactory catalytic activities have been explored. In this Letter, we demonstrate that MoN nanosheets array on carbon cloth (MoN NA/CC) acts as a high-performance NRR electrocatalyst toward NH3 electrosynthesis in 0.1 M HCl under ambient conditions. This catalyst achieves a large NH3 yield of 3.01 × 10–10 mo1 s–1 cm–2 and a Faradaic efficiency of 1.15% at −0.3 V vs reversible hydrogen electrode with strong electrochemical durability and selectivity. Density functional theory calculations reveal that MoN NA/CC catalyzes NRR via the Mars–van Krevelen mechanism.

Remarkable enhancement of the alkaline oxygen evolution reaction activity of NiCo₂O₄ by an amorphous borate shell

Inorganic Chemistry Frontiers (2017)

Xuqiang Ji Xiang Ren Shuai Hao Fengyu Xie Fengli Qu

Surface introduction of an amorphous borate shell on NiCo₂O₄ greatly boosts its electrochemical water oxidation activity under alkaline conditions. To achieve 10 mA cm⁻² in 1.0 M KOH, NiCo₂O₄@Ni–Co–B/CC needs an overpotential of only 270 mV.

One‐Step Synthesis of Boron Nitride Quantum Dots: Simple Chemistry Meets Delicate Nanotechnology

Chemistry - A European Journal (2016)

Bingping Liu Shihai Yan Zhongqian Song Mengli Liu Xuqiang Ji

Abstract Herein, a conceptually new and straightforward aqueous route is described for the synthesis of hydroxyl‐ and amino‐functionalized boron nitride quantum dots (BNQDs) with quantum yields (QY) as high as 18.3 % by using a facile bottom‐up approach, in which a mixture of boric acid and ammonia solution was hydrothermally treated in one pot at 200 °C for 12 h. The functionalized BNQDs, with excellent photoluminescence properties, could be easily dispersed in an aqueous medium and applied as fluorescent probes for the detection of ferrous (Fe 2+ ) and ferric (Fe 3+ ) ions with excellent selectivity and low detection limits. The mechanisms for the hydrothermal reaction and fluorescence quenching were also simulated by using density functional theory (DFT), which confirmed the feasibility and advantages of this strategy. It provides a scalable and eco‐friendly method for preparation of BNQDs with good dispersability and could also be generalized to the synthesis of other 2D quantum dots and nanoplates.
