Modified Graphene Supported Ruthenium as an Efficient Electrocatalyst for Hydrogen Evolution Reaction in Alkaline Media
With the large consumption of fossil energy, people began spend attention and energy to find and unearth renewable energy, and electrolytic water hydrogen evolution is an ideal scheme. The key to hydrogen production from electrolytic water is to find an appropriate catalyst. Here, we have developed an efficient and durable catalyst by introducing Ruthenium into porous graphene oxide (Ru@PGO), When the current density is 10 mA cm−2, the the corresponding overpotential and Tafel slope are 40.2 mV and 89.68 mV dec−1 respectively, and its stability is very excellent. Through theoretical calculation, it is found that ΔGH* is low, and reveals the effect of pore structure and oxygen introduction on the catalyst. It provides a feasible scheme for the preparation of new catalyst for hydrogen evolution reaction (HER).
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
