Developing more efficient and greener catalytic strategies for upgrading biomass to value-added chemicals fuels is crucial a sustainable future. Recently, single-atom catalysts have played an important role in this mission.
Abstract There is a misconception that sustainability only related to greenhouse gas emissions into the atmosphere, and this risk which planet exposed. Sustainability multidimensional concept must advance simoutaneously on several fronts, such as urgent need increase energy, clean water, air, food, mobility, health, poverty reduction. All problems of these multi‐dimensions are aggravated by continuous growth world population, mainly in economic socio‐environmental issues. However, biggest...
Furfural is a platform molecule that can be catalytically converted using cascade series of reactions into levulinic esters, essential compounds used as fuel additives. Bifunctional catalysts containing Lewis and Brønsted acid sites such zeolites are commonly for these conversions. However, microporous often present diffusional restriction due to the size similarity furfural other molecules zeolites’ micropores. Thus, incorporating mesopores in materials through post-synthetic protocols...
In this study, two materials based on reduced graphene oxide (rGOH or rGOE) were synthesized through the Hummers methodology and a more sustainable electrochemical method. These extensively characterized tested as catalysts in solketal production. Both rGOH rGOE demonstrated significant catalytic activity, achieving 66.18% 63.97% conversion rates, respectively. The activity of was 30 times efficient than homogeneous catalyst p-Toluenesulfonic acid. Pseudo-homogeneous heterogeneous kinetic...
A BRIEF OVERVIEW ON SINGLE-ATOM CATALYSIS: CONCEPTS AND APPLICATIONS. Catalytic processes became extremely important for the development of our society, especially after second industrial revolution. Thus, research more efficient catalysts is an obstacle to overcome achieve cheaper processes, higher yields, and selectivity desired products. In this context, single-atom catalysis emerges as a promising alternative unite advantages traditional homogeneous heterogeneous catalysis. Catalysis by...
In a context where society has strong dependence on fossil fuels, research in biofuels is necessary to offer more sustainable future.In this perspective, biodiesel attracted much attention due its high applicability.As byproduct of synthesis, glycerol one the main concerns field because demand lower than supply, and also accumulation industry may transform it into waste.To overcome issue, several studies have proposed investing chemical conversion.These reactions allow many industrial...
