Supercritical thermal stability of endothermic hydrocarbon fuel(超临界条件下吸热型碳氢燃料氧化安定性研究)
Zhejiang Daxue xuebao. Lixue ban, 2007 采用超临界反应装置测定了吸热型碳氢燃料HDF-1的氧化安定性能.结合吸光度分析结果、红外谱图以及氧化沉积量的测定结果，考察了2，6-二叔丁基对甲酚（BHT）对燃料氧化安定性能的影响.结果表明，如果反应时间为3 h，BHT能够将燃料的氧化沉积量降低64%，有效地提高燃料的氧化安定性能，但BHT对缓解燃料颜色变化并无明显效果.

Cu‐Based Catalysts Design Toward Electrochemical CO2 Reduction to Valuable Multi‐Carbons Products
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Electrochemical reduction of CO2 to multi‐carbon products (e.g., C2+, ethene, ethanol, etc.) not only effectively decreases the CO2 concentration in atmosphere but also shows great potential economic benefits due to these exploitable value‐added products. The Cu‐based catalysts have caught much attention in CO2 electroreduction due to the good

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Biomass‐derived quinones are promising green and sustainable cathode materials for sodium‐ion batteries (SIBs), yet their practical application is hindered by poor cycling stability due to dissolution in conventional electrolytes. Herein, we demonstrate that sodiumation is an effective strategy to enhance both rate capability and cycling ...

Zhejiang Daxue xuebao. Lixue ban, 2008 在流化床中评价了用于甲烷二氧化碳氧化重整制合成气反应的Ni-Al2O3/SiO2催化剂体系（NixAlSi，x代表Al的质量分数，Ni的质量分数为4%）的催化性能.利用XRD，CO2(O2)-TPD，积炭量测定等手段对催化剂进行了表征.结果表明，Al2O3的添加促进了Ni金属的分散；增强了对CO2和O2的吸附能力，使催化剂的抗积炭性能得到很大的提高，延缓了催化剂的失活.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Jianzhu Gangjiegou Jinzhan, 2011 本文考虑将干冰放置于空心钢管混凝土构件的内部空心中,干冰将逐步气化,变为二氧化碳气体,通过设计一定的试验设备来控制其压力,使得该高压气体能在较短时间内有效地渗透进混凝土中,与混凝土中的Ca（OH）2发生碳化反应。试验研究表明,该试验装置安全可靠,能使空心钢管混凝土内表面发生一定深度的碳化,为二氧化碳在改良混凝土性能的应用方面提供了一种新思路。本试验的研究内容,目前国内外还没有相关报道,属国内外首创。
