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 ...

Shuitu Baochi Xuebao, 2019 以法国梧桐叶片和枝条为原料在500℃下通过限氧裂解法制成生物质炭，进而采用批量吸附法探究了不同溶液初始pH、吸附时间、溶液初始Pb2+浓度对生物质炭吸附效果的影响，并通过拟合吸附动力学曲线和吸附等温线方法初步研究吸附机理。结果表明，与法国梧桐枝条炭相比，叶片炭矿质元素组成相对较为复杂，官能团种类较丰富。2种生物质炭均在吸附时间为24 h时、初始pH为5时达到最大吸附量，叶片炭的最大吸附量比法国梧桐枝条炭高25.6%。2种生物质炭的动力学吸附过程均符合准二级动力学方程，表明吸附速率主要受化学因素控制 ...

Shuitu Baochi Xuebao, 2020 土壤吸附可溶性有机碳（DOC）对土壤有机碳的循环转化有重要影响。为进一步明确田间实际情况下盐碱水田土壤对DOC的吸附规律，选取吉林西部不同盐碱程度的5块水田土壤（P1、P2、P3、P4和P5），采用室内模拟试验，在静止条件下培养70天，模拟研究了土壤在自然状态下对不同浓度DOC的吸附特征，分析了理化性质对DOC最大累积吸附量的影响。结果表明：土壤对DOC的吸附速率在试验初期较快，然后逐渐减弱并达到平衡，Elovich方程可描述土壤对DOC的动力学吸附特征，且适用于土壤对不同浓度DOC的吸附 ...

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−
