5-Hydroxymethylfurfural oxidation; 2,5-Furandicarboxylic acid; W-doped; Jahn-Teller distortion; NiOOH
ABSTRACT
In this work, W doping induces the structural distortion of the in situ formed NiOOH generated by reconstruction, effectively modulating its electronic states near the Fermi level, resulting in the broadening of the eg* band, which promotes electron transfer between the catalyst and HMF as well as the adsorption of HMF, significantly enhancing the activity of HMFOR. -

High-entropy alloy; Carbon dioxide reduction; Multi-carbon; Ethylene
ABSTRACT
The CuMoRuFeW HEA catalyst enhances CO2 activation and improves selectivity for C2 product formation by overcoming the limitations of linear scaling relationships, achieving a Faradaic efficiency (FE) of 69.9% for C2 products. The combination of active sites reduces the energy barrier, thereby enhancing CO2ER efficiency. -

ABSTRACT
Sulfur-fumigation harms Lycium barbarum and health. Current SF-Lb detection is complex. This manuscript uses a chemiresistor with Cu3(HHTP)2 thin film to quickly distinguish SF-Lb from Lb with an accuracy of ∼100% based on their differences in volatolomics. -
