Integration of Three-Dimensional Printed Flow-through Photoreactor with Z-Scheme Photocatalytic Membrane for Sunlight-Drivable Micropollutant Removal from Water

ACS Materials Letters (2025)

Pin Song Yunmei Shi Yuhong Cai Wei Jiang Xiaoyu Fang

Sunlight is an ideal energy source for the catalytic degradation of micropollutants from water. However, it remains a challenge to achieve efficient sunlight-driven micropollutants degradation. Here, we report the integration of a 3D printed flow-through photoreactor with a Z-scheme AgI/Bi2WO6/poly(ether sulfone) (AgI/Bi2WO6/PES) photocatalytic membrane for light-driven removal of antibiotics and steroid hormones. Notably, the rates of photocatalytic micropollutants removal are achieved above 96% over a wide range of concentrations, from 200 ng L–1 to 10 mg L–1, setting the highest record as compared to the reported cases to date. Under natural sunlight, an impressive 99% removal rate for LEV is demonstrated. We technologically determine the limiting factor for micropollutant degradation, while the photocatalytic mechanism is fundamentally elucidated with experimental evidence. This work provides an effective approach to removing micropollutants under sunlight and offers insights for the design of water treatment devices through the synergy of 3D printed photoreactors and heterojunction materials.

Enabling Unconventional "Alternating-Distal" N2 Reduction Pathway for Efficient Ammonia Electrosynthesis.

PubMed (2025)

Chu Zhang Qing Wang Zeyu Li Hengjie Liu Lixiang Zhong

Electrocatalytic dinitrogen reduction reaction under ambient conditions offers a promising approach for sustainable and decentralized green ammonia production. Conventionally, the general understanding on the reaction path is that the N2 reduction follows either individual associative alternating or distal pathways, where efficient N2 activation and selective NH3 production are very challenging. Herein, an unconventional "alternating-distal" hybrid pathway was achieved by shifting the "*NHNH2→*NH2NH2" to "*NHNH2→*NH + NH3" step to boost NH3 synthesis with an amorphous CeMnOx electrocatalyst. In this unconventional process, N2 activation was realized through π back donation on the Mn site, while the Mn/Ce dual active sites could regulate the intermediate configurations to avoid the nitrogen-containing by-product formation for guaranteeing high NH3-producing Faradaic efficiency. Such "alternating-distal" hybrid pathway was validated by a set of in situ spectroscopic analyses and theoretical calculations. In a neutral media, an average ammonia production rate of 82.8 μg h-1 mg-1 and an outstanding Faradaic efficiency of 37.3 % were attained on the amorphous CeMnOx electrocatalyst at a mild potential of -0.2 V, along with an impressive durability of over 40 hours. This work validated an unconventional mechanism in electrocatalytic ammonia synthesis, which might be extended to other catalytic process with multiple possible reaction paths.

Dial the Mechanism Switch of VN from Conversion to Intercalation toward Long Cycling Sodium‐Ion Battery

Advanced Energy Materials (2020)

Shiqiang Wei Changda Wang Shuangming Chen Pengjun Zhang Kefu Zhu

Abstract Transition metal nitrides are promising energy storage materials in regard to good metallic conductivity and high theoretical specific capacity, but their cycling stability is impeded by the huge volume change caused by the conversion reaction mechanism. Here, a simple strategy to produce an intercalation pseudocapacitive‐type vanadium nitride (VN) by one‐step ammonification of V 2 C MXene for sodium‐ion batteries is reported. Profiting from a distinctive layered structure pillared by Al atoms in the layer spacing, it delivers a high capacity of 372 mA h g −1 at 50 mA g −1 and a desirable rate performance. More importantly, it shows remarkably long cycling stability over 7500 cycles without capacity attenuation at 500 mA g −1 . As expected, it is found that the intercalation pseudocapacitance plays an important role in the excellent performance, by using in situ X‐ray diffraction and ex situ X‐ray absorption structure characterization. Even more remarkable, are the high energy and power density of the sodium‐ion capacitor after coupling with a carbon‐based cathode. The hybrid device possesses an energy density of 78.43 Wh kg −1 at power density of 260 W kg −1 . The results clearly show that such a unique‐layered VN with outstanding Na storage capability is an excellent new material for energy storage systems.

Recent advances in 2D transition metal compounds for electrocatalytic full water splitting in neutral media

Materials Today Advances (2020)

Juan Peng Wen‐Fei Dong Zhe Wang Meng Yang Wanyi Liu

Water electrolysis in neutral media has attracted concerted research efforts because of its practical applications including microbial electrolysis of wastewater and large-scale hydrogen generation by direct electrolysis of seawater. Because the corrosion of electrochemical devices is effectively reduced in neutral environments, the associated cost is consequently lowered. In this context, two-dimensional transition metal compounds have enjoyed extensive applications in the field of renewable energy because of their abundant storage capacity, easily regulated electronic structure, and unique physical and chemical features. As such, this review summarizes recent advances in the use of two-dimensional transition metal compounds as hydrogen evolution, oxygen evolution, and bifunctional catalysts for neutral water splitting. Some engineering strategies to enhance electrocatalytic performances are also discussed. Finally, the current challenges and future opportunities in bifunctional electrocatalysts for full water splitting are presented.

Metal-Based Ionic Liquid Induced Strategy for Loading Single Atoms and the Coordination Mode Effect on CO₂ Photoreduction

ACS Materials Letters (2024)

Mei Zhang Yao Wu Xingwang Zhu Pin Song Hailong Chen

The effect of single atom positions and coordination environments on photocatalytic performance is not clear. Herein, Co single atoms with surface coordination or lattice coordination mode in Bi24O31Br10 atomic layers are presented for CO2 photoreduction. A novel strategy based on metal-based ionic liquids is developed to prepare stable surface single atom tuned catalysts. In contrast to high-coordinated lattice-doped Co single atoms, the low-coordinated Co single atoms loaded on the catalyst surface play a crucial role in decreasing the activation energy and rate-limiting step energy barriers. The surface-modified Co single atoms work as a polarization center to drive photogenerated electron migration, accelerate reaction kinetics, and enhance CO2 reduction activity. Benefiting from these features, Cosur-Bi24O31Br10 exhibits a more enhanced CO2 photoreduction performance than Bi24O31Br10 and Colat-Bi24O31Br10. This work provides insight into the effect of positions of single atoms on photocatalytic behavior and offers a strategy to load other low-coordinated surface metal single atoms.
