Special Issue Information

Dear Colleagues,

With the rapid development of urbanization and industrialization, the problems of environmental pollution and energy shortages are becoming increasingly prominent, which seriously threaten the survival and development of mankind. Some advanced electrochemical technologies (such as fuel cells, metal–air batteries, water electrolysis, carbon dioxide capture, nitrogen fixation, etc.) based on catalytic reactions have been considered as promising solutions to solve these problems. Electrocatalytic materials (electrocatalysts) play a critical role in the above advanced electrochemistry technologies. In recent years, great progress has been made in the design, synthesis, application and catalytic mechanism of nano/microstructure electrocatalytic materials (electrocatalysts), which strongly promoted the development of the above key technologies in environmental and energy catalysis.

This Special Issue aims to highlight recent progress and trends in novel electrocatalytic materials for various electrochemical technologies and reactions. We cordially invite investigators to contribute reviews, original articles, short communications, and perspectives that focus on topics including, but not limited to, the following:

  • Novel electrocatalytic materials for fuel cells, metal–air batteries, water splitting, batteries, etc.;
  • Novel electrocatalytic materials for reduction reactions, including ORR, HER, CO2RR, nitrogen reduction reaction, nitrate reduction reaction, etc.;
  • Novel electrocatalytic materials for oxidation reactions, including OER, urea oxidation reaction, hydrazine hydrate oxidation reaction, the oxidation of small organic molecules and biomass, etc.;
  • The design, synthesis and modification of novel electrocatalytic materials and their applications in the field of energy, environment and biomedical science, etc.

Environmental pollution caused by the use of fossil fuels is becoming increasingly serious, necessitating the adoption of clean energy solutions. Lithium-ion batteries (LIBs) have attracted great attention due to their high energy density and currently occupy a dominant commercial position. Metal oxide materials have emerged as promising anode materials for the next generation of LIBs, thanks to their high theoretical capacity. However, the practical application of these materials is hindered by their substantial volume expansion during lithium storage and poor electrical conductivity. In this work, a zinc/iron bimetallic hybrid oxide composite, ZnO/ZnFe2O4/NC, is prepared using ZIF-8 as a precursor (ZIF-8, one of the metal organic frameworks). The N-doped porous carbon composite improves the volume change and optimizes the lithium-ion and electron transport. Meanwhile, the ZnFe2O4 and ZnO synergistically enhance the electrochemical activity of the anode through the built-in heterojunction to promote the reaction kinetics at the interface. As a result, the material delivers an excellent cycling performance of 604.7 mAh g−1 even after 300 cycles of 1000 mA g−1. This study may provide a rational design for the heterostructure and doping engineering of anodes for high-performance lithium-ion batteries. Full article
