Special Issue Information

Dear Colleagues,

Energy is an indispensable and important resource in modern society, which directly affects the world's economy, environment, and sustainable development. However, many countries still rely on fossil fuels. The exploitation and use of these fuels has led to serious environmental problems and resource depletion. Therefore, we need to find a sustainable form of energy to replace traditional fuels. Electrocatalysis technology, as an efficient and environmentally friendly energy conversion tool, is attracting increasing attention from scientists and engineers. Electrocatalysis technology is a technology that uses electric energy to promote reaction activity and adjust active site. Because of its advantages of simple operation, rapid reaction, and strong controllability, it has broad application prospects in energy conversion, chemical synthesis, environmental protection and other fields.

This Special Issue, ‘’New Insights into Electrocatalysis for Energy Storage and Conversion’’, focuses on the synthesis, application, and mechanism analysis of electrocatalysts in energy conversion, storage, and environmental applications. All studies (experimental and theoretical) within the scope of this Special Issue, including original research and review articles, short communications, and perspective articles, are invited for submission.

The electrochemical advanced oxidation process is a promising technology for tackling wastewater pollution, but it suffers from poor pH adaptability and slow catalytic kinetics in a neutral and alkaline environment in a homogeneous system, as well as fast release of metal ions in a heterogeneous system. Herein, a boron- and nitrogen-codoped carbon nanotube-encapsulated transition metal (M@BN-C, M–Co, Cu) cathode with a similar structure was synthesized to explore activity trends and mechanisms. Characteristics of Co@BN-C and Cu@BN-C cathodes were examined and compared with the previously synthesized Fe@BN-C bifunctional cathode. The activity of sulfamethazine (SMT) degradation by the Co@BN-C cathode was higher than both Fe@BN-C and Cu@BN-C at pH = 3 and pH = 7, respectively. However, the activity of Co@BN-C was also higher than that of Cu@BN-C and lower than that of Fe@BN-C at pH = 9. It was observed that OH and 1O2 were the main reactive oxygen species (ROS) using Co@BN-C and Cu@BN-C cathodes. The Co@BN-C generated the highest OH for efficient SMT degradation through abundant H2O2 generation, exhibiting the highest catalytic activity compared with the Cu@BN-C cathode. Overall, SMT degradation on the Co@BN-C cathode demonstrated better catalytic performance in real wastewater. This study provided insights into the fundamental catalytic trends and mechanisms of ROS production via the M@BN-C cathode, thus contributing to the development of the M@BN-C cathode for catalytic organic pollutant degradation.
