Special Issue Information

Dear Colleagues,

Green catalytic processes in chemical production, energy conversion, and environmental remediation have greatly promoted the sustainable development of the chemical industry and human society. For environmental catalysis, the development of powerful, efficient, and environmentally friendly catalysts and processes has always been in urgent need to completely remove toxic and hazardous substances from polluted air, soil, and wastewater. In addition, considerable efforts are still needed to conduct in-depth mechanistic studies on the relationship between material morphology, surface chemistry, and catalytic performance, which can not only provide meaningful guidance for rational material design but also realize potential applications in environmental science. Advanced oxidation processes have been proven to be one of the most effective environmental remediation technologies, which usually involve photocatalysis and activation of superoxides (such as ozone, hydrogen peroxide, peroxymonosulfate, and persulfate) to produce reactive species for the transition/decomposition of pollutants in polluted systems. 

This Special Issue aims to introduce the latest progress and advances in the design, synthesis, characterization, and evaluation of advanced metals, metal oxides, nanocarbons, and novel hybrids in photocatalysis, advanced oxidation processes, and other catalytic oxidation and environmental pollution prevention and control.

This paper systematically reviews the recent advances in catalytic systems and reaction mechanisms for the synthesis of crotonaldehyde via aldol condensation using acetaldehyde as the feedstock. Firstly, the structural characteristics, reactivity, and important applications of crotonaldehyde in fine chemicals are outlined, with particular emphasis on the limitations of traditional homogeneous base-catalyzed processes, such as difficulty in separation and environmental pollution caused by waste streams. On this basis, heterogeneous catalytic systems are discussed in detail, focusing on the progress of metal oxides, aluminosilicate zeolites, and heteroatom zeolites in regulating acid–base properties, active site structures, and reaction pathways. Furthermore, the typical carbanion mechanism and direct condensation mechanism in aldol condensation are summarized, and the catalyst deactivation and by-product formation mechanisms are analyzed. Finally, perspectives on the construction of efficient and green catalytic systems and future research directions are proposed, aiming to provide theoretical guidance for process optimization and catalyst design in crotonaldehyde synthesis from acetaldehyde.
