Nanomaterial-Mediated Green Catalysis

Dear Colleagues,

Human ingenuity has driven exploration beyond borders in the pursuit of innovations for survival, comfort, and entertainment. The 18th century marked a pivotal shift towards large-scale production during the Industrial Revolution, bringing both progress and significant environmental challenges. For an extended period, the consequences were overlooked, but contemporary society now faces pressing challenges. Global leaders collaborate in pivotal events such as the signing of the Paris Agreement in 2015, representing a collective endeavor towards a sustainable future. The UN's Agenda 2030, conceived during the Paris Agreement, outlines 17 goals and 169 targets as a robust plan guiding the world towards a more sustainable trajectory by 2030.

In this context, the scientific community encounters innovative challenges in developing materials and processes that are more sustainable. This involves minimizing waste, enhancing catalyst performance through materials engineering, and, critically, substituting toxic solvents with more sustainable alternatives. Additionally, the priority is to seek a reduction in or minimization of effluents, with a focus on efficient water reuse and the utilization of residual biomass to obtain new products with added value, aligning with the fundamental principles of a circular economy.

In the energy sector, the transition to cleaner sources takes precedence, with the replacement of fossil fuel-based matrices. In this context, renewable sources play an essential role, with green hydrogen and water-splitting processes highlighted as promising alternatives aligned with the pursuit of a more sustainable and clean energy future.

This Special Issue, titled "Nanomaterial-Mediated Green Catalysis", aims to cover recent advances in the synthesis of new materials and processes aligned with the concept of green catalysis. Topics of interest for this Special Issue include the following:

• Catalysis in Sustainable Hydrogen Production: Exploration of innovative catalytic methods for efficient and sustainable hydrogen production as a clean energy source.
• Degradation of Emerging Contaminants through Catalysis: Investigation of catalytic approaches for the effective degradation of emerging contaminants, contributing to environmental remediation and the preservation of water and soil quality.
• Catalytic Synthesis for Obtaining Value-Added Molecules: Development of innovative catalytic processes to obtain new molecules, emphasizing the creation of products with added value, promoting a circular and sustainable economy.
• Carbon Dioxide (CO₂) Capture: Exploration of advanced strategies for efficient carbon dioxide capture, aiming to reduce emissions and mitigate environmental impact.
• Use of Biochar in Catalysis: Exploring Sustainable Alternatives: This topic explores the application of biochar in catalytic processes, highlighting its unique properties and contributions to a more environmentally friendly approach in catalysis.
