Special Issue Information

Dear Colleagues,

The depletion of fossil resources has intensified the need for sustainable alternatives, particularly in converting renewable biomass into high-value chemicals. This Special Issue aims to explore advanced methodologies and catalyst systems for the selective conversion of biomass into valuable chemicals, such as ethylene glycol, 1,2-propanediol, and isosorbide, as well as innovations in direct seawater electrolysis for hydrogen production.

Historically, the production of ethylene glycol and 1,2-propanediol relied heavily on petrochemical processes, which are unsustainable and environmentally taxing. Early research into biomass conversion showed mixed results due to low selectivity and efficiency. Recent advancements have highlighted the potential of using catalysts containing alkali metals, tungsten, tin, and other transition metals to optimize the conversion process, improving both yield and selectivity. For isosorbide production, research has focused on optimizing catalysts and reaction conditions to improve the overall efficiency and sustainability of cellulose conversion.

In addition, direct seawater electrolysis has emerged as a promising technology for hydrogen production within the carbon-neutral energy framework. This method does not compete with the increasing demand for pure water and utilizes renewable resources such as solar, tidal, and wind energy. However, the development of high-selectivity, high-efficiency, and corrosion-resistant multifunctional electrocatalysts remains a significant challenge.

This Special Issue aims to provide a comprehensive review of these topics, including the selective regulation of ethylene glycol and 1,2-propanediol production using glycerol and cellulose, and the conversion of cellulose to isosorbide. It also covers advancements in direct seawater electrolysis for hydrogen production, focusing on electrocatalyst development and process optimization. This Special Issue aims to offer valuable insights and guidance for future research in sustainable biomass conversion and hydrogen production, contributing to the development of eco-friendly and efficient processes.

This study explores a sustainable method for synthesizing quinazoline derivatives through visible light-driven photocatalysis using curcumin-sensitized titanium dioxide (TiO2) nanoparticles. A one-pot, three-component reaction involving aldehydes, urea/thiourea, and dimedone was utilized to efficiently produce quinazoline compounds. The photocatalytic performance of curcumin-sensitized TiO2 (Cur-TiO2) was compared to pure TiO2 (P-TiO2), with Cur-TiO2 showing significantly enhanced activity. Under optimized conditions—light intensity of 100 mW/cm2, catalyst concentration of 1 mg/mL, and a reaction time of 40 min—a 97% product yield was achieved. The Cur-TiO2 catalyst demonstrated excellent reusability, maintaining high efficiency over four consecutive cycles with minimal performance loss. This work underscores the potential of natural dye sensitization to extend light absorption of TiO2 into the visible spectrum, providing an eco-friendly and cost-effective approach to sustainable organic synthesis.

Direct seawater electrolysis is a promising technology within the carbon-neutral energy framework, leveraging renewable resources such as solar, tidal, and wind energy to generate hydrogen and oxygen without competing with the demand for pure water. High-selectivity, high-efficiency, and corrosion-resistant multifunctional electrocatalysts are essential for practical applications, yet producing stable and efficient catalysts under harsh conditions remains a significant challenge. This review systematically summarizes recent advancements in advanced electrocatalysts for seawater splitting, focusing on their multifunctional designs for selectivity and chlorine corrosion resistance. We analyze the fundamental principles and mechanisms of seawater electrocatalytic reactions, discuss the challenges, and provide a detailed overview of the progress in nanostructures, alloys, multi-metallic systems, atomic dispersion, interface engineering, and functional modifications. Continuous research and innovation aim to develop efficient, eco-friendly seawater electrolysis systems, promoting hydrogen energy application, addressing efficiency and stability challenges, reducing costs, and achieving commercial viability.
