Abstract

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 ΔG_H* 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).

改性石墨烯负载钌作为碱性介质中析氢反应的高效电催化剂

随着化石能源的大量消耗，人们开始花心思和精力寻找和发掘可再生能源，而电解水制氢就是一个理想的方案。电解水制氢的关键在于找到合适的催化剂。当电流密度为 10 mA cm-2 时，相应的过电位和 Tafel 斜率分别为 40.2 mV 和 89.68 mV dec-1，其稳定性非常好。通过理论计算发现，ΔGH*较低，揭示了孔结构和氧气引入对催化剂的影响。它为制备氢进化反应（HER）的新型催化剂提供了一种可行的方案。

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.
