Electrochemical hydrogen production from biomass

Electrocatalytic transformation of biosourced organic molecules

“…Moreover, the catalyst formulation, electrode potential, electrolyte composition, reactant concentrations and flow rate are levers allowing precisely tuning activity and selectivity towards a given product [2]. Organic electrosynthesis has received paramount attention at both laboratory and industrial scales for different applications such as pollutant treatment [3], synthesis of chemicals [4], and energy/hydrogen production [5]. Table 1 gives some examples of organic electrosynthesis processes developed at the industrial scale [1].…”

Producing green hydrogen in an efficient way using a nexus of a waste-biomass derived catalyst and a cost-effective & scalable electrode platform

“…Different protocols have been used for the production of hydrogen, namely the thermochemical process, 8 biological process, 9 direct solar water splitting process, 10 and electrochemical process. 11 In comparison with other methods described, an electrochemical method for hydrogen production is among the most admired technologies for energy. 12 Hydrogen produced by the electrochemical process demonstrates high efficiency and it is an ecologically clean method because no greenhouse gases are formed.…”

Electroreforming of Glucose/Xylose Mixtures On PdAu Based Nanocatalysts

“…The electro-conversion of oxygenated compounds from biomass is now considered as an interesting mean for the simultaneous production of both value-added compounds at the anode and hydrogen at the cathode of an electrolysis cell. [1,2] Lignocellulosic biomass is a very abundant non-edible raw material that has attracted huge interest in bio-refineries for production of fuels and chemicals. [3] According to the feedstock, lignocellulosic biomass contains 30-45 % cellulose, 20-50 % hemicellulose and around 20 % lignin.…”

“…[4] Lignin is composed of an amorphous heteropolymer network of phenyl propane units held together by different linkages and has interest for second generation biofuel production. Cellulose is a linear crystalline polymer composed of glucose units [4] linked via ß- (1,4) glycosidic bonds, whereas hemicelluloses are branched polymers of mainly pentoses (xylose, arabinose) and hexoses (mannose, glucose, galactose). [5] In fact, glucose and xylose are the main sugars in hydrolysates after lignocellulosic biomass pretreatments to separate lignin from carbohydrates, and it has been proposed that the economically feasible production of valuable chemicals from lignocellulosic biomass should also lean on the conversion of both xylose and glucose.…”
