Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Formic acid (FA) is considered to be a safe and convenient hydrogen source; however, achieving controlled and efficient FA dehydrogenation under mild conditions using stable solid catalysts remains a significant challenge. Pd‐based catalysts have been extensively studied due to their superior catalytic activity to other metal catalysts.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Gongye shui chuli, 2013 制备了天然斜发沸石负载TiO2光催化剂,以染料活性黑溶液为降解目标物,紫外光为光源,在超声波协同作用下光催化降解染料废水,对催化剂的合成条件、催化活性及其重复使用性进行了研究。结果表明,在200℃焙烧温度下,由钛酸四丁酯与斜发沸石复合制备的催化剂具有最大的光催化活性,且其催化活性与纯TiO2相近。制备的催化剂质量稳定,可重复使用。超声波-光催化协同作用对染料的脱色率好于单一的光催化降解作用。

Gongye shui chuli, 2021 TiO2光催化剂因其耐用性、低成本、低毒性、超亲水性以及出色的化学稳定性，广泛应用于水中有机污染物的降解。但TiO2的带隙（3.2 eV）较宽，导致TiO2的光生电子-空穴对易复合，无法充分利用可见光，限制了其实际应用。染料敏化可将TiO2的光响应范围扩展到可见光区域，提高其光催化活性。综述了染料敏化TiO2光催化剂的原理、染料敏化剂的分类、不同染料敏化剂的应用现状及效果，以期为染料敏化在TiO2光催化剂中的应用提供参考。
