“…Sulfonated carbon catalysts are considered promising alternatives to conventional homogeneous acid catalysts because they are inexpensive, less corrosive, and have a low environmental impact [ 50 , 51 ]. They can be obtained by the sulfonation of a variety of carbon-based materials, including carbon nanotubes [ 52 ], graphene [ 53 ], mesoporous carbons [ 54 ], and polyaromatic molecules [ 55 ].…”

In this work, a novel sustainable approach was proposed for the integral valorisation of Arctium lappa (burdock) seeds and roots. Firstly, a preliminary recovery of bioactive compounds, including unsaturated fatty acids, was performed. Then, simple sugars (i.e., fructose and sucrose) and phenolic compounds were extracted by using compressed fluids (supercritical CO2 and propane). Consequently, a complete characterisation of raw biomass and extraction residues was carried out to determine the starting chemical composition in terms of residual lipids, proteins, hemicellulose, cellulose, lignin, and ash content. Subsequently, three alternative ways to utilise extraction residues were proposed and successfully tested: (i) enzymatic hydrolysis operated by Cellulases (Thricoderma resei) of raw and residual biomass to glucose, (ii) direct ethanolysis to produce ethyl levulinate; and (iii) pyrolysis to obtain biochar to be used as supports for the synthesis of sulfonated magnetic iron-carbon catalysts (Fe-SMCC) to be applied in the dehydration of fructose for the synthesis of 5-hydroxymethylfurfural (5-HMF). The development of these advanced approaches enabled the full utilisation of this resource through the production of fine chemicals and value-added compounds in line with the principles of the circular economy.

Biomass‐derived materials can help develop efficient, environmentally friendly and cost‐effective catalysts, thereby improving the sustainability of hydrogen production. Herein, we propose a simple method to produce nickel and molybdenum composites decorated spent coffee grounds (SCG) as an efficient catalyst, SCG(200)@NiMo, for electrocatalytic hydrogen production. The porous carbon supporter derived form SCG provided a larger surface, prevented aggregation during the high temperature pyrolysis, optimized the electronic structure by N and provided a reducing atmosphere for the oxides reduction to form heterojunctions. The sieved SCG showed obvious improvement of HER performance and enhanced conductivity and long‐term durability. The obtained SCG(200)@NiMo exhibits the highest electrochemical performance for the hydrogen evolution reaction process, as evidenced by the overpotential of only 127 mV at a current density of ɳ10 and 97.7% catalytic activity retention even after 12 h of operation. This work may stimulate further exploration of efficient electrocatalysts derived from biomass.

Electrical double-layer capacitance can be enhanced through the development of carbon materials possessing elevated specific surface area, porosity, and electrical conductivity. In this study, we demonstrate a facile approach to synthesizing carbon materials with a meticulously controlled pore structure of ZIF-67 by precise manipulation of the precursor solution quantities.The concentration of the precursor affects the crystal sizes of ZIF-67 due to the different nucleation rates. After the carbonization of the crystals, smaller cobalt nanoparticles formed within the carbon materials derived from the ZIF-67 crystal with larger dimensions. Removal of the nanoparticles by acid treatment induced the formation of porous carbon, resulting in the enhanced performance of electrical double-layer capacitors. The nanoporous carbon, derived from the largest-sized ZIF-67 template, exhibited a remarkable specific capacitance of 157 F/g at a current density of 1 A/g, retaining an impressive 85% of this value after 30,000 charging/discharging cycles at 16 A/g.
