About this Research Topic
Chemical and energy conversion is a major problem for human well-being and ecosystem health in the context of global change and human population growth. Catalysis, via either heterogeneous catalysis, photocatalysis or electrocatalysis, is an efficient and economic strategy to covert chemicals and energy into diverse and value-added forms of chemicals and energy. Heterogeneous catalysts allow the direct conversion between different chemicals with minimized energy consumption. While artificial photocatalysts and electrocatalysts convert solar energy and electric energy into chemical energy respectively. Through electrocatalysis, chemical reactions (e.g., CO2 reduction reaction, water splitting, N2 fixation, etc.) can occur by the reduction of flow electrons. Similarly, chemical reactions can also take place gently under the light irradiation. On the other side, these catalytic processes can be monitored by in-situ instruments, such as UV-vis spectroscopy, dark-field scattering, surface-enhanced Raman scattering, Raman, X-ray absorption spectroscopy.
The goal of this Research Topic is to collect the latest discoveries in electrocatalytic and photocatalytic systems utilizing artificial electrocatalysts and photocatalysts to efficiently convert electric energy and solar energy into chemical bonds. The induced hot charges/electromagnetic field, light scattering and plasmon resonance, which are affected by the interaction of light with nanomaterials (plasmonic metals or semiconductors), can promote the catalytic reaction. Besides, the electric energy can provide the flow electrons to decrease the chemical reaction energy. However, there are several critical issues that need to be addressed, including the catalytic efficiency, selectivity, economy, and reaction mechanisms. Rational design and synthesis of electrocatalysts and photocatalysts of nanomaterials are the main methods to solve those challenges.
