The development of green and sustainable energy is of great significance to maintain a clean and livable environment in modern society. For instance, H2 possesses high energy density and zero carbon emission, which potentially alleviate the energy crisis and environmental pollution caused by fossil fuels. Converting CO2 into fuels again potentially provides a sustainable energy supply and mitigates the excessive emission of greenhouse gas CO2. The photocatalysis and electrocatalysis are promising techniques to achieve these clean and renewable energy. Highly active and cheap photo- and electro- catalytic materials are the key to the widespread application of photocatalysis and electrocatalysis. Although various catalysts such as semiconductors, polymers, metals, compounds and composites have been developed, catalysts are still not effective and cheap enough for commercial applications.

Catalytic materials with high efficiency and inexpensive price have broad application prospects in the fields of photocatalysis and electrocatalysis. Up to now, novel photocatalytic and electrocatalytic materials have been extensively studied. For example, the transition metal-based oxides, hydroxides, carbides, phosphate, nitride, sulfides are extensively studied for water splitting (e. g. hydrogen evolution reaction and oxidation evolution reaction) and CO2 reductions. Moreover, some carbon-based materials show proper bandgaps, conductivity, and activity for various photocatalytic and electrocatalytic reactions. In this Research Topic, the recent advances in photocatalytic and electrocatalytic materials for producing renewable fuels are addressed. This topic is aimed at collecting the most novel progress in designing, fabrication, characterization, and mechanism of photocatalysts and electrocatalysts for water splitting, H2 evolution, CO2 reduction, N2 fixation, and other related properties.

This Research Topic particularly focuses on the photocatalytic and electrocatalytic materials for reactions of hydrogen evolution, oxygen evolution, CO2 reductions, and so on. Photocatalytic and electrocatalytic materials for fixation of nitrogen, environment remediation, ammonia synthesis, urea synthesis, nitrate reduction are also welcomed. We welcome the submission of Original Research, Reviews, Mini-Reviews, and Perspectives on related topics, including but not limited to the following topics:

• Photocatalytic and electrocatalytic materials water splitting to produce H2 and O2;
• Photocatalysts and electrocatalysts for CO2 reduction reactions;
• Materials for photocatalytic and electrocatalytic oxygen reductions, organic synthesis, fuel cell, and environment remediation.

Keywords: Photocatalyst, Electrocatalyst, Water Splitting, CO2 Reduction, Hydrogen Energy


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
