Boosted oxidative dehydrogenation of lactic acid into pyruvic acid on polyvinylpyrrolidone modified Fe₂O₃

Abstract

Polyvinylpyrrolidone can regulate the growth of crystal faces and formation of oxygen vacancies, in which a synergy of the facet and vacancies boosted the oxidative dehydrogenation of lactic acid into pyruvic acid.

Nanostructured nickel–cobalt alloy/rGO-SWCNT thin film as an efficient electrocatalyst for hydrogen evolution reactions

“…Long-term durability is an important factor for any electrocatalyst. 36,37,[54][55][56] Here, the time-dependent chronopotentiometric tests at a constant applied current density of 10 mA cm À2 and 100 mA cm À2 for CoNi21 were performed respectively, and the results are shown in Fig. 7a.…”

Highly efficient production of 2,3-pentanedione from condensation of bio-derived lactic acid over polymorphic ZrO2

“…7 Overall, bio-derived lactic acid (LA) is particularly appealing due to its simple synthesis via biomass fermentation, as well as the expected increased availability and lower cost. 10,11 Several studies have been conducted to convert LA to chemicals such as acrylic acid, pyruvic acid, 12,13 propionic acid, 14 acetaldehyde, poly(lactic acid), and 2,3-pentanedione. 15 However, the raw lactic acid must be further purified to technical or analytical grade before being used in this described process.…”
