Abstract: The invention relates to the method of preparing catalyst based on platinum (Pt), with a low Pt content, dispersed on carrier containing graphene quantum dots (Pt/GQDs or Pt/GO-GQDs) used for fuel cell with excellent activity in the electrochemical oxidation reaction of alcohol (for example, methanol, ethanol), applied as an anode catalyst for direct alcohol fuel cell (DAFC). At the same time, the invention also refers to the catalyst obtained by this method as an anode catalyst for DAFC.

Abstract: The present invention relates to the additive for solid fuel combustion processes (coal, biomass) that both improves fuel efficiency, reduces fuel consumption, and has the ability to prevent sludge formation in combustion chamber and reduce pollutant emission, ensuring stable and highly efficient furnace operation even when using bad-quality fuel. The additive includes the activator component with high polarity; the active component capable of generating active sites; the auxiliary component capable of promoting the generation of active centers; the stabilizing component able to regulate the physicochemical properties and helping to create a stable additive according to the ratio of components (% mass) as follows: Activator component: 20-30 Active component: 50-60 Auxiliary component: 5-9 Stabilizing component: 1-5, and Solvent: suitable In addition, the invention also relates to the production process for this additive.

Abstract: The present invention relates to a process for the production of basic biosolvents derived from inedible vegetable oil or animal fat or waste fatty acid composition by one-pot reaction between inedible vegetable oil or animal fat or waste fatty acid, and at least one ester of short-chain organic acid having 2, 3 or 5 carbon atoms, derived from biomass, in the presence of heterogeneous catalysts. In addition, the invention also relates to basic biosolvents, comprising alkyl esters of fatty acid, trieste of glycerin, esters of short-chain organic acids having 2, 3 or 5 carbon atoms, suitable for preparing many types of biosolvents, depending on application requirements.
