The Synthesis of PtFe/C and Its Application in Non-Enzymatic Glucose Sensor

Ding Yu,Li Yibin,Wu Huimin,Wang Shengfu,Xia Qinghua

20 wt% PtFe/C catalysts were prepared by a chemical reduction method at high temperature. The catalysts were characterized by X-ray diffraction, transmission electron microscopy, and electrochemical testing. The sensor based on PtFe/C showed a detection limit of 0.03 mM and high sensitivity with linear range from 0.1 mM to 13.5 mM. The sensor still had high selection for glucose in the presence of commonly interfering species, such as ascorbic acid, acetamidophenol, and uric acid. The as-prepared glucose sensor has good anti-interference performance.

Selective hydrodeoxygenation of 5-hydromethylfurfural to 2,5-dimethylfuran over PtFe/C catalyst

Zhijiao Huang,Yong Liu,Lungang Chen,Xinghua Zhang,Jianguo Liu,Chenguang Wang,Qi Zhang,Longlong Ma

2,5-dimethylfuran (DMF), a promising biomass-derived fuel, is synthesized via the hydrodeoxygenation of 5-hydroxymethylfurfural (HMF). This study focuses on the inherent activity of a 5Pt5Fe/C catalyst for HMF hydrodeoxygenation to DMF. The catalyst exhibited exceptional performance, achieving a remarkable DMF yield of 99.6 %. It displayed specific selectivity for C = O bond hydrogenation and C O bond cleavage in diverse substrates, producing high yield of 2-methylfuran from furfural and furfury alcohol, and high yield of toluene from benzaldehyde, benzyl alcohol. In-depth characterizations unveiled valuable insights into the 5Pt5Fe/C catalyst's properties, emphasizing a harmonious balance between metal and acid sites due to the interactive synergy between Pt and Fe species, enhancing hydrodeoxygenation activity. Additionally, the catalyst demonstrated satisfactory stability, maintaining a commendable DMF yield over five reaction cycles despite observed changes.
