Abstract
Water splitting enables efficient conversion of renewable energy storage with great potential for performance improvement. Therefore, the development of economic and high-performance electrocatalysts is crucial. This work proposed a strategy that the tightly packed CoS2/MoS2 heterostructure was synthesized on carbon paper as a bimetallic electrocatalyst for water splitting applications. Electrochemical test results present that CoS2@MoS2/CP has excellent catalytic activity and hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) overpotentials of 135 mV and 348 mV were achieved in 1 M KOH. Two-electrode water splitting device anode and cathode were fabricated using CoS2@MoS2/CP. When the current density is 10 mA·cm−2, the cell voltage is only 1.51 V. The 10-h long-term durability test exhibited that its stability is better than most reported non-precious metal electrocatalysts. This work provides a new research route for preparing efficient and stable electrocatalysts for better applications in water splitting.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
