Green and Sustainable Catalytic Process

Topic Information

Dear Colleagues,

Catalysis as a discipline plays a decisive role in chemical process industries as catalytic reactions are central to the production of fuels and chemicals. Environmentally friendly catalysts with higher activity, selectivity, efficiency, and durability are continuously being developed, making chemical processes greener and more sustainable.

This Topic, “Green and Sustainable Catalytic Process”, focuses not only on catalyst preparation, characterization, and fundamental studies in the field of catalysis but also covers innovations in the field and potential industrial implementations. This Topic pertains (but is not limited) to the following:

• Biomass valorization;
• Waste valorization (e.g., CO₂, municipal and industrial waste);
• Catalyst preparation and valorization;
• Catalyst recycling;
• Catalytic reactions in nonconventional solvents (e.g., ionic liquids, supercritical solvents);
• Heterogeneous, homogeneous, enzymatic, and organocatalysis;
• Photo- and electrocatalysis;
• One-pot and tandem reactions;
• Alternative solvents;
• Process intensification (e.g., ultrasound, microwaves, plasma);
• The chemical reaction engineering of sustainable and green processes;
• Kinetic modeling;
• Reactor design;
• Technological advancements;
• Catalysis for renewable energy
• Lifecycle assessment and techno-economic analysis;
• Sustainable chemical products and fuels.

Fungal laccases are promising oxidative enzymes for bioremediation applications, particularly in the degradation of synthetic dyes present in industrial effluents. Here, we evaluated the inhibitory effects of sodium chloride (NaCl) and sodium sulfate (Na₂SO₄) on the activity of Trametes versicolor laccase and its ability to decolorize Congo Red (CR), Malachite Green (MG), and Remazol Brilliant Blue R (RBBR). Enzyme assays revealed concentration-dependent inhibition, with IC₅₀ values of 0.22 ± 0.04 M for NaCl and 1.00 ± 0.09 M for Na₂SO₄, indicating stronger inhibition by chloride. Kinetic modeling showed mixed-type inhibition for both salts. Despite this effect, the enzyme maintained significant activity: after 12 h, decolorization efficiencies reached 95 ± 4.0% for MG, 88 ± 3.0% for RBBR, and 75 ± 3.0% for CR, even in the presence of 0.5 M salts. When applied to a mixture of the three dyes, decolorization decreased only slightly in saline medium (94.04 ± 4.0% to 83.43 ± 5.1%). FTIR spectra revealed minor structural changes, but toxicity assays confirmed marked detoxification, with radicle length in lettuce seeds increasing from 20–38 mm (untreated dyes) to 41–48 mm after enzymatic treatment. Fungal growth assays corroborated reduced toxicity of treated dyes. These findings demonstrate that T. versicolor laccase retains functional robustness under ionic stress, supporting its potential application in saline textile wastewater remediation. Full article
