Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Graphitic carbon nitride (g‐C3N4) doped with 3d transition metals (3d‐TM@g‐C3N4) has gained attention as a noble metal‐free alternative for oxygen evolution and reduction reactions (OER/ORR). Yet the key mechanisms driving its performance remain debated, especially across different charge states.

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

Gongye shui chuli, 2010 分别采用兼氧/好氧工艺和好氧工艺对苯酚丙酮废水进行生物处理研究。该废水具有高盐分、高有机物浓度、低pH的特点，进水CODCr约1 187 mg/L。监测结果表明，使用兼氧/好氧工艺处理，兼氧槽出水平CODCr为1 021 mg/L，CODCr降低20.9%，而BOD5则升高11.9%，B/C升高了41.5%。这说明经过兼氧槽处理后，废水的可生化性进一步提高。再经过好氧槽处理，最终出水平均CODCr为63.0 mg/L。但仅采用好氧工艺的好氧槽出水平均CODCr为75.2 mg/L ...

Gongye shui chuli, 2003 采用生物膜法缺氧-好氧工艺处理磺胺生产废水,当进水COD为2357mg/L时,出水COD可达到284.3mg/L,去除率达87.92%。试验研究结果表明:温度对工艺运行效果影响很大,当系统温度满足25℃时,缺氧段和好氧段HRT分别为8.1h和21.3h,工艺运行即可达到如上效果;当缺氧段温度降至15℃时,缺氧段和好氧段HRT分别延长至12.7h和33.1h,才可达到同样的效果,但好氧段温度必须满足25℃,才能使出水COD达到300mg/L以下的目标。

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 ...
