Special Issue Information

Dear Colleagues,

Heterogeneous catalysis is significant for the selective conversion of small molecules to valuable compounds in the industry. Different types of energy (e.g., thermal, solar, electrical and mechanical energy) can be transformed into useful chemical energy (e.g., desired chemical compounds) via nanocatalysts. For instance, the reduction in CO2, H2O splitting, fixation of N2, activation of CH4 and organic synthesis are hot spots in the field of heterogeneous catalysis.     

The design and construction of nanocatalysts with symmetrically or asymmetrically electronic/geometric structures play vital roles in obtaining satisfactory catalytic performance with high selectivity, activity and stability. Moreover, the creative and effective heterogeneous catalytic protocols can lead to the synthesis of symmetrical or asymmetrical organic compounds with controlled stereoselectivity. Thus, it requires sustained and long-term efforts from researchers to realize important chemical reactions in a sustainable, green, energy-saving and efficient way by establishing robust heterogeneous catalytic systems.

This Special Issue of Symmetry is dedicated to the theme “Symmetry/Asymmetry in Heterogeneous Catalysis for the Activation of Small Molecules.” The issue is open to submissions (research or review articles) involving any aspects of heterogeneous catalysis. The research of interest will cover asymmetry/symmetry in the design of catalyst materials or synthesis methods of organic compounds, (but not limited to) in the fields of the reduction in CO2, H2O splitting, fixation of N2, activation of CH4 and organic synthesis.

Photocatalytic technology has been considered as an efficient protocol to drive chemical reactions in a sustainable and green way. With the assistance of semiconductor-based materials, heterogeneous photocatalysis converts solar energy directly into chemical energy that can be readily stored. It has been employed in several fields including CO2 reduction, H2O splitting, and organic synthesis. Given that near-infrared (NIR) light occupies 47% of sunlight, photocatalytic systems with a NIR response are gaining more and more attention. To enhance the solar-to-chemical conversion efficiency, precise regulation of the symmetric/asymmetric nanostructures and band structures of NIR-response photocatalysts is indispensable. Under the irradiation of NIR light, the symmetric nano-morphologies (e.g., rod-like core-shell shape), asymmetric electronic structures (e.g., defect levels in band gap) and asymmetric heterojunctions (e.g., PN junctions, semiconductor-metal or semiconductor-dye composites) of designed photocatalytic systems play key roles in promoting the light absorption, the separation of electron/hole pairs, the transport of charge carriers to the surface, or the rate of surface photocatalytic reactions. This review will comprehensively analyze the four main synthesis protocols for the fabrication of NIR-response photocatalysts with improved reaction performance. The design methods involve bandgap engineering for the direct utilization of NIR photoenergy, the up-conversion of NIR light into ultraviolet/visible light, and the photothermal effect by converting NIR photons into local heat. Additionally, challenges and perspectives for the further development of heterogeneous photocatalysts with NIR response are also discussed based on their potential applications. Full article
