Gongye shui chuli, 2021 随着世界人口的增加及工业的快速发展，水资源利用面临越来越大的挑战。为缓解水资源短缺问题，各行各业广泛应用循环冷却水系统。伴随着冷却水使用过程的不断循环与浓缩，水中的矿物质含量不断增加，从而引起设备管道结垢。垢的存在不仅降低了传热效率与水流速度，还会产生垢下腐蚀，严重影响设备的性能和使用寿命，导致生产成本极大增加。添加阻垢剂是普遍认为的防止结垢最直接和有效的方法。传统的阻垢剂会造成二次污染，因此无毒、高效且降解性良好的绿色阻垢剂引起研究者的关注。对近年来绿色阻垢剂在国内外的研发应用现状进行了综述 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Water electrolysis is a promising method for green hydrogen production, but slow hydrogen evolution reaction (HER) kinetics require efficient catalysts. In this study, we develop a Ni3S2/MoS2 heterostructure electrocatalyst using a work‐function‐driven electronic modulation strategy combined with a self‐sacrificial template approach.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Ni3S2 has emerged as a promising catalyst for the electrochemical oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA), driven by its distinctive physicochemical properties. However, its practical catalytic efficiency is severely hindered by abundant electrochemically inactive surface sites and poor ...
