High‐Entropy Engineering Enables Highly Exposed Mn3+ Active Sites and Stable Mn–O Coordination in α‐MnO2 for Efficient Bifunctional Oxygen Electrocatalysis

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Anchoring Polyoxometalate (PMo11Fe) on ZnO Nanosheet for Construction of a Novel S‐Scheme Heterojunction Toward Efficient Photodegradation of Levofloxacin Antibiotics

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Rational Design of Bimetallic MOF‐Derived Cu/Co@N‐C Nanocubes for Ultrasensitive Electrochemical Nitrite Detection

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.

Dual‐Functional Carbon Dots as Electrolyte Additives for Enhancing Cathode Catalysis and Anode Stability in Li–O2 Batteries

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...

煤气废水好氧—缺氧—好氧生物处理研究

Gongye shui chuli, 2006
煤气废水生物处理目前遇到的主要问题是系统运行不稳定及氨氮去除率低，针对这些问题开发出好氧—缺氧—好氧生物处理工艺。实验表明，新工艺在入水COD较高的条件下可以稳定运行，系统中一级好氧白土-活性污泥单元作用较大。系统在平均入水COD为2204 mg/L、氨氮为244mg/L的条件下，COD和氨氮去除率分别可达87.6%和80%，HRT的降低对系统COD去除率影响不大，但使氨氮去除率降低到67%，主要是由于一级好氧单元硝化作用减弱所致。该工艺提高了煤气废水生物处理的功效，特别是在去除氨氮方面具有很大的优势 ...
