Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. for the publication of high quality, agenda-setting research related to materials for energy harvesting, conversion, storage, and transport as well as cleaner environment. EEM publishes research work of significant general interest with high impact on society-relevant technological advances. The journal scope is intentionally broad and the journal recognizes the complexity of issues and challenges related to energy and environmental materials, and therefore, particularly welcomes experimental and theoretical work of interdisciplinary nature across basic science and engineering disciplines. The areas include but are not limited to materials and composites for: • Photovoltaics & photoelectrochemistry • Thermoelectricity, piezoelectricity, and triboelectricity • Batteries, fuel cells, and supercapacitors • Bioprocessing • Environmental remediation • Clean air • Carbon capture, storage, and utilization • Clean water, waste water treatment, and desalination • Devices with multifunctionality
