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

open access: yesRare 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.

碳毡修饰立体化电极及电氧化脱硫性能的研究 [PDF]

open access: yes, 2014
低浓度SO2脱除是防治SO2污染的技术难题,电氧化脱硫过程传质问题严重,需要实现电极的立体化;且过程中多使用恒定电位氧化。本论文开展了立体化脱硫电极的制备及其脱硫性能的研究,选题具有重要的理论意义和实际应用价值。Pt/C催化剂通过超声、陈化、浸渍等过程修饰到碳毡立体骨架上,实现电极的立体化,使电氧化脱硫空间得以拓展;催化剂负载到碳毡上可以提高稳定性。 高低电位振荡脱硫模式比单一恒电位模式脱硫效果好,所用时间短;其脱硫效果与电位转换频率和高低电位作用时间比有关。恒电位 ...

MoS2‐Modified Bamboo‐Like Nitrogen‐Doped Carbon Nanotubes Encapsulating Ni Nanoparticles Enabling Synergistic Adsorption–Catalysis for High‐Performance Lithium–Sulfur Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

超级电容器高倍率多孔碳电极材料的研究 [PDF]

open access: yes, 2014
活性碳是目前商品化超级电容器普遍采用的电极材料,研究与开发高倍率碳基电极材料对提升超级电容器的输出性能,拓展其应用领域具有十分重要的意义。本论文针对商品化活性炭中孔率低、电子导电性低、倍率性能差的问题,通过制备具有不同孔径分布、不同石墨化程度和含有不同表面官能团的多孔碳材料,系统研究了多孔碳微观结构、相组成、表面官能团和电容性能之间的关系。首先,采用催化石墨化的方法制备了高比表面积的部分石墨化活性炭。研究结果表明,活性炭的石墨化程度越高,其倍率性能越好,但过高的石墨化程度会造成活性炭比电容的显著下降 ...

Defect Engineering of Carbon Frameworks Driven All‐Slope Hard Carbon Anodes for Fast‐Charging Sodium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Fast‐charging capability is one of the crucial factors determining the application prospects of sodium‐ion batteries (SIBs). Nevertheless, the mismatched sodium storage kinetics and Coulombic efficiency (CE) in hard carbon anodes are bottlenecks in the implementation of fast‐charging SIBs. Herein, we propose a facile pre‐carbonization strategy
