Abstract[English]
The invention relates to a method for the selective electro-oxidative fragmentation of lignin using an electrochemical system, comprising the following steps: (i) synthesis of a nickel-cobalt electrocatalyst; (ii) obtaining an anode coated with the electrocatalyst; and (iii) selective fragmentation and oxidation of solubilised lignin in an electrochemical reactor comprising said anode, in which vanillic acid and syringic acid are obtained as preferred products.[Spanish]
La presente invención hace referencia a un método para la fragmentación electro-oxidativa selectiva de lignina por medio de un sistema electroquímico, que comprende las siguientes etapas: (i) síntesis de un electrocatalizador de níquel y cobalto (ii) obtención de un ánodo recubierto con el electrocatalizador y (iii) fragmentación y oxidación selectiva de lignina solubilizada en un reactor electroquímico que comprende dicho ánodo, en el que se obtienen como productos preferentes ácido vanílico y ácido siríngico.[French]
