The Competition between 4-Nitrophenol Reduction and BH₄^- Hydrolysis on Metal Nanoparticle Catalysts.

ABSTRACT: Assessing competitive environmental catalytic reduction processes via NaBH₄ is essential, as BH₄^- is both an energy carrier (as H₂) and a reducing agent. A comprehensive catalytic study of the competition between the borohydride hydrolysis reaction (BHR, releasing H₂) and 4-nitrophenol reduction via BH₄^- on M⁰- and M/M' (alloy)-nanoparticle catalysts is reported. The results reveal an inverse correlation between the catalytic efficiency for BH₄^- hydrolysis and 4-nitrophenol reduction, indicating that catalysts performing well in one process exhibit lower activity in the other. Plausible catalytic mechanisms are discussed, focusing on the impact of reaction products such as 4-aminop
