Biomass processing wastes (humins) are anticipated to become a large-tonnage solid waste in the near future, owing to the accelerated development of renewable technologies based on utilization of carbohydrates. In this work, the utility of humins as a feedstock for the production of activated carbon by various methods (pyrolysis, physical and chemical activation, or combined approaches) was evaluated. The obtained activated carbons were tested as potential electrode materials for supercapacitor applications and demonstrated combined micro- and mesoporous structures with a good capacitance of 370 F g (at a current density of 0.5 A g ) and good cycling stability with a capacitance retention of 92 % after 10 000 charge/discharge cycles (at 10 A g in 6 m aqueous KOH electrolyte). The applicability of the developed activated carbon for practical usage as a supercapacitor electrode material was demonstrated by its successful utilization in symmetric two-electrode cells and by powering electric devices. These findings provide a new approach to deal with the problem of sustainable wastes utilization and to advance challenging energy storage applications.

“…g-valerolactone employed in the production of biofuels and biopolymers, 1,4-pentanediol, which is an intermediate for biopolymers preparation, 2-methyltetrahydrofuran for biofuels and for the pharmaceutical industry as an alternative green solvent, and N-substituted pyrrolidones, are just some examples of the possible high value-compounds derived from levulinic acid. [74,[78][79][80][81][82] Moreover, biomass-derived 2,5-dimethylfuran (DMF) and 5hydroxymethylfurfural (HMF) have gained, as well, increased attention in the past years due to their potential for the preparation of valuable chemicals ( Figure 6B-D). [83,84] Among the wide range of examples that can be given, it is worth to mention the synthesis of p-Xylene (PX), which is an important commodity compound in the petrochemical industry and is employed as comonomer, together with monoethylene glycol (MEG) for the preparation of polyethylene terephthalate (PET).…”

Environmental catalysis plays a crucial role in sustainable development by the design of novel catalytic materials and technologies. Several environmental issues are addressed by catalytic processes such as decomposition of pollutants for air, water and soil remediation, hydrogen production, CO2 reduction and biomass valorization, just to name a few. This contribution aims to provide a general overview of the main concepts and current advances in the environmental catalysis field. Special attention has been paid to photocatalysis and electrocatalysis, as sub‐areas of catalysis with tremendous potential in sustainable applications, in particular with regard to the promotion of sustainable energies. In this contribution, the partnership between Catalysis and Green Chemistry is presented, in a comprehensive way, as an open research line which is imperative and decisive for a more sustainable future.

Homogeneous (HCl) and heterogeneous catalysts (various zeolites) were combined to enhance the upgrading of glucose into two different platform molecules: 5‐hydroxymethylfurfural (HMF) and levulinic acid (LA). β‐Zeolite was the most active material for the glucose isomerization to fructose, improving also the activity of HCl for the subsequent steps. Reaction time, temperature, and pH were then modified, identifying 140 °C, 200 ppm of HCl, and 5 h as the optimum conditions for HMF formation (41 % selectivity; 0.06 mol L−1) and 140 °C, 400 ppm of HCl, and 24 h for LA formation (34 % selectivity; 0.12 mol L−1). This new approach is also relevant because of significant changes to the mechanism for humins formation. All results are successfully fitted to a kinetic model simultaneously considering both catalytic mechanisms.
