Rhenium disulfide (ReS 2 ) as a catalyst is promising in water splitting for hydrogen evolution reaction (HER) owing to its unique structure and physiochemical property. Chemical vapor deposition (CVD) is one of effective means for the fabrication of high-crystallinity ReS 2 . At present, conductivities of typical substrates used for the CVD growth are mostly poor. The transfer to a conductive support or other engineering for improving the conductivity is necessarily required for the application of HER electrode. However, the damage to original structure and the introduction of impurities are highly possible in the process. The cost of time and material is also increased. In this work, we propose that a wood-derived carbon framework is used as a working electrode supporting CVD-grown ReS 2 nanosheets in electrocatalytic HER. The optimal HER electrode with unique pore-through structure exhibits effective electrochemical surface area of 521 cm ECSA 2 and outstanding stability over 11 h. Such a carbon framework derived from natural wood is earth-abundant, ecofriendly and renewable, which can be potentially applied in the green energy industry.

支持 CVD 生长的 ReS2 的木材衍生电极可高效稳定地生产氢气

二硫化铼（ReS 2 ）作为一种催化剂，由于其独特的结构和理化性质，在析氢反应（HER）的水分解中很有前景。化学气相沉积 (CVD) 是制造高结晶度 ReS 2 的有效手段之一。目前，用于CVD生长的典型基板的导电性大多较差。HER电极的应用必须需要转移到导电载体或其他工程以提高电导率。然而，在此过程中极有可能破坏原始结构和引入杂质。时间和材料成本也增加了。在这项工作中，我们建议使用木材衍生的碳框架作为工作电极，在电催化 HER 中支持 CVD 生长的 ReS 2 纳米片。具有独特通孔结构的最佳 HER 电极表现出 521 cm ECSA 2 的有效电化学表面积和超过 11 小时的出色稳定性。这种源自天然木材的碳框架资源丰富​​、环境友好且可再生，可潜在应用于绿色能源行业。
