摘要

二维ReSe2作为析氢反应（HER）催化剂，由于其独特的1T′结构和在基面上的各向异性物理性质而备受关注。本工作采用水热合成技术在碳布（CC）基底上直接制备了ReSe2纳米片。使用高铼铵（NH4ReO4）、硼氢化钠（NaBH4）、硒（Se）粉末和去离子水制备反应溶液。研究了反应物浓度和反应时间对ReSe2/CC催化HER性能的影响。当NH4ReO4、Se和NaBH4的浓度分别为0.05M、0.065M和0.200M时，ReSe2/CC表现出最佳的HER催化性能，在10mAcm-2的电流密度下过电位为197mV，Tafel斜率为142mVdec-1，ECSA为325cm2。讨论了ReSe2/CC HER过程的形成机理和工作机理。

Synthesis and electrocatalytic performance for hydrogen evolution reaction of ReSe2 nanosheets

Two-dimensional ReSe2 as catalyst for hydrogen evolution reaction (HER) has attracted attention due to its unique 1T′ structure and anisotropic physical properties in base planes. In this work, ReSe2 nanosheets were directly prepared on a carbon cloth (CC) substrate by hydrothermal synthesis technology. The reaction solution was prepared using ammonium perrhenium (NH4ReO4), sodium borohydride (NaBH4), selenium (Se) powder and deionized water. The effects of reactant concentrations and reaction time on the catalytic properties of the ReSe2 /CC for HER were researched. When the concentration of NH4ReO4, Se and NaBH4 is 0.05 M, 0.065 M and 0.200 M, ReSe2/CC shows the optimal HER catalytic properties with overpotential of 197 mV at current density of 10mAcm-2 , Tafel slope of 142 mVdec-1 and ECSA of 325cm2 . The formation mechanism and working mechanism in the HER process of ReSe2/CC are discussed.
